Powering green chemistry with microspheres and microcapsules
n green chemistry processes, there is a need for administering actives in well- Idefined forms as well as using processes and materials in a recoverable and sustainable manner. For these needs, it is mandatory to discuss shape, size and form of dosage, carriers and recovery methods. Microspheres and microcapsules manufactured with the BRACE Microsphere processes offer the unique possibility Thorsten Brandau to combine encapsulation with low energy production process as well as recovering of carriers with resource saving means. The monomodal size and extremely tight BRACE GmbH, Germany size distribution of the particles produced with such processes, allow the precise dosage or the handling of catalysts in a most advantageous manner. Particles co-author: Christian Augustin produced with the patented BRACE-microsphere processes can be used for BRACE GmbH, Germany producing catalysts and catalyst carriers in a size range from about 50 micrometers up to 8 mm, or the encapsulation of an extremely wide range of materials for release on definable triggers such as mechanical force, temperature, pH, solubility, and many others. The processes can be used to reform materials from sub-zero to 1500°C, while most materials can be easily processed at room temperature to form perfectly round spheres. Such spheres show extremely well definable release properties and can be tailored to almost any application. Applications so far realized range from catalysts and catalyst carriers easily recoverable and reusable, over bioreactors, cell encapsulation for biochemical processes, agricultural applications such as reducing the pesticide and fertilizer needs, to energy processing for sustainable construction materials, recovering oil and gas, solar cells, energy storage and many more applications. In the field of alternative fuel production or the thermal conversion of biomass, there are several applications already that make use of those properties. As the scalability of the processes is easy, straight forward and unlimited, also large and very large scale productions can easily be covered, at both, a low energy and resource use that scales less than the production output.

Cyclodextrins as versatile tools for the preparation of UV-and visible-light responsive mesoporous photocatalysts he development of sustainable chemical processes is becoming a major Tfeature of research for the protection of human health and the environment. In this context, the heterogeneous photocatalysis, using semiconductor-liquid interfaces as catalytic sites for solar light-stimulated redox reactions, has emerged as a promising technology for environmental clean-up applications. Among the
various metal oxide semiconductors, titanium dioxide (TiO2) has become one of the most important photocatalysts because of its chemical stability and unique ability in catalyzing water splitting, air purification and water decontamination.
For effective solar energy utilization, modification of TiO2 surface with noble metal nanoparticles provides an alternative approach for extending the absorption wavelength from the ultraviolet (UV) to the visible region. In this
Rudina Bleta context, Au/TiO2 composites have attracted much interest as efficient plasmonic photocatalysts owing to the ability of Au nanoparticles to absorb light in the visible University of Artois, France region and TiO2 to efficiently separate the photogenerated electrons and holes at the metal-semiconductor interface. In this work, we describe a simple colloidal self-assembly approach towards highly active UV- and visible-light photocatalysts that takes advantage of the ability of cyclodextrins to direct the self-assembly of
TiO2 colloids in a porous network over which Au nanoparticles can be uniformly dispersed. The performance of these nanocomposites is evaluated in the visible light photocatalytic degradation of the phenoxyacetic acid (PAA), a widely utilized herbicide, frequently detected in natural water. The CD-driven approach is simple and provides a versatile route towards a broad range of nanostructured composites with promising properties for environmental clean-up applications. Biography Rudina Bleta has completed her PhD from Nancy University and Post-doctoral studies from University Paul Sabatier at the CIRIMAT-Carnot Institute in Toulouse. In 2012, she joined the Professor Monflier’s team at the UCCS-Artois as a Lecturer. Her research expertise are in developing new synthesis approaches, especially from soft chemistry routes, to design novel nanostructured porous materials, with a specific focus on the development of heterogeneous catalysts for environmental and sustainable energy applications.

Systems approach to identify sustainable chemical innovations that encompass life-cycle impacts
oo often we cherry-pick sustainability topics: there is a focus on green Tchemistry, climate change, on circular economy, or types of poverty. Rarely do we look at the many faceted challenges of sustainability as deeply interconnected, The root causes of these challenges lie in the fundamental unsustainability of the way we organize our businesses and societies. Based on the laws of thermodynamics and sociological research on the healthy functioning of socio-ecological systems, the Framework for Strategic Sustainable Development (FSSD) identifies four root causes of unsustainability. Together, they constitute the boundary conditions or design principles for humanities to sustain within the limits of planet earth. In this way, the conditions constitute a science- Elze C. van Hamelen based definition of success for sustainable design, selection and management of chemicals, materials and products. The Natural Step, Germany The Strategic Life Cycle Assessment (SLCA) applies the sustainability principles in each phase of the product life cycle – creating a ‘heat map’, merging perspectives on chemicals, circular economy and SDGs, and providing direction for effective sustainability innovation. By applying these sustainability principles rigorously and strategically, the systems perspective that underlies it assures holistic and integrated solutions, avoiding solutions that only combat symptoms, or solutions that cause complications in other domains. The Natural Step has been helping organisations apply these principles since the early 1990’s. Here we focus on application and insights around circular / sustainable product innovation. Biography Elze is an Advisor at The Natural Step Germany, and Associate Partner at the Sustainable Growth Associates network. Elze holds an MBA in Sustainable Management and an MA degree in Organisational Sociology, combining different perspectives within an organisation, such as policy, strategy, change, culture, cooperation, behaviour and communication. She is passionate about the strategic implementation of sustainability using The Natural Step framework, and she’s convinced that innovations in chemistry and materials management are key to accelerating the transition to sustainability

3+ Effect of Al /clay ratio on C3H6-SCR over iron catalysts supported on aluminum pillared montmorillonite (FE-AL-PILC) ron based catalysts supported on aluminum pillared montmorillonite (Fe-Al- PILC) were prepared. The methods including XRD, H -TPR, Py-FTIR, Uv-Vis I 2 spectroscopy, ICP, N2 adsorption-desorption, etc. were used to characterize the basic physical and chemical properties of the catalysts. The characteristics of selective catalytic reduction of NO by propylene on the catalyst surface were studied experimentally in a fixed-bed reactor, and the effect of the Al3+/clay ratios on the
physicochemical properties of the catalyst and the SCR-C3H6 was investigated. The
results show that 9Fe/Al-PILC has higher SCR-C3H6 denitrification performance, 3+ e.g., 100% of NO conversion to N2 was tested over 400°C. The Al /clay ratio plays more important role on NO conversion than the calcination temperature of the carrier. According to the Al3+/clay ratios, the order of catalytic activity is 9Fe/ Yaxin Su Al-PILC-10>9Fe/Al-PILC-20>9Fe/Al-PILC-5>9Fe/clay>9Fe/Al-PILC-40. Al3+ increased the specific surface area of the montmorillonite dramatically, and the Donghua University, China catalyst had micropores and mesoporous structures. When the Al3+/clay ratio was 10 mmol/g of the pillared montmorillonite had the best physicochemical property. co-authors: Wenyan Qian and Wenyi Deng In the Fe/Al-PILC catalysts, the iron oxides are highly dispersed on the surface Donghua University, China of the support. H2-TPR shows that the reduction of Fe2O3 phase determines the SCR activity of the catalyst. With the increase of Al3+/clay ratio, the reducing
temperature of the reducing process Fe3O4→Fe gradually increases. UV-Vis results showed that Al3+ increased the oligomer FexOy, and the activity of the catalyst was positively correlated with the oligomer FexOy. Py-IR results showed that both Lewis acid and Bronsted acid were favorable for the selective catalytic reduction of NO. The 9Fe/Al-PILC-10 catalyst had the best activity, which was related to its higher Brønsted acid content.

Design and use of an imidazolium ion-tagged fluorescent chemosensor for sensing metal ions in water
n present scenario for the accurate detection of a contaminant in unprocessed Ienvironmental samples, there is need to develop innovative chemosensors which provides excellent selectivity and sensitivity to heavy and transition metal ions. A major challenge of developing chemo sensors is the design of chelators possessing both high affinity and high selectivity. Most of the metal ions are carcinogens and lead to serious health concerns, hence, fast and accurate detection of metal ions has become a critical issue. We have developed a simple fluorescent chemosensor containing only imidazolium ionic tag along with Schiff base for the detection of metal ion contamination in water. Ionic tags are entirely composed of ions, are drawing extensive interest, since they can be tailored to satisfy the functional requirements for building organic materials by changing either the cation or Bharti Khungar anion species. Ionic tags have achieved great success in acting as luminescent materials, exhibit strong fluorescence with high quantum yields. Schiff bases also BITS Pilani, India are readily obtained by simple synthetic procedures and usually exhibit strong emission upon binding to specific foreign ions. For this work, 8-aminoquinoline co-author: Vaishali Saini was used as an amine source, which is a traditional fluorophore, which is widely BITS Pilani, India employed in the design of sensors due to its coordination function. Details of synthesis, characterization and sensing studies will be shown in presentation during the conference.

Laws to enhance green chemistry and protect humanity
ith the development, human beings have created a background of Wdestruction that necessitates incorporation of green chemistry in daily life. Adoption of this revolutionary and diverse discipline has led to significant environmental benefits, innovation and a strengthened economy. Laws have contributed significantly to enhance the concept of green chemistry in the United States. Toxic Substances Control Act (TSCA) of 1976 governs the majority of industrial chemicals; Pollution Prevention Act 1990 has helped foster new approaches for dealing with pollution by preventing environmental problems before they happen. In 2008, the State of California approved two laws aiming to encourage green chemistry, launching the California Green Chemistry Initiative. One of these statutes required California's Department of Toxic Substances Vandana Khungar Control (DTSC) to develop new regulations to prioritize chemicals of concern and promote the substitution of hazardous chemicals with safer alternatives. Such University of Rajasthan, India laws should also be implemented in India to combat accidents like Bhopal gas tragedy. Due to the leak of gas in the world's worst industrial disaster in 1984 at the Union Carbide India Limited (UCIL) pesticide plant, 500,000 people were killed due to methyl isocyanate and other gases. This was an incident of the past, but a good example of how mankind is still struggling with the use of pesticides in the present is cancer train. The train commences from Abohar and leaves from the Bathinda station to reach Rajasthan's Bikaner, where patients undergo treatment at the Acharya Tulsi Regional Cancer Treatment and Research Centre (RCC). In Malwa (Punjab), farmers use 15 different pesticide sprays and the unregulated and excessive use of chemical fertilizers and pesticides have resulted in farmers and their families living in a cesspool of toxicity. Presently, rise in cancer deaths (18/day) in Punjab can be attributed to indiscriminate use of Agro-chemicals after the green revolution. When developed nations like America can grow in the realm of green chemistry, then why not a developing nation likes India? The present study deals with recommendation of drafting and implementation of such laws in India and rest of the world, the details will be presented in the conference.

High value-added cellulose products prepared from low-grade cellulose resources
ellulose is the most abundant renewable organic material with a host of current Cand potential uses. Starting with dissolving pulp as a purified raw material, cellulose is converted industrially into regenerated materials (fibers, films, food casings, membranes, sponges, etc.) and cellulose derivatives (ethers and esters). However, until now, the main resource for commercial cellulose production are concentrating on the highly pure cellulose resources such as, cotton linters and dissolving wood pulp. This fact makes the cellulose resource expensive to obtain. In contrast, the low-grade lignocellulosic biomass has become attractive as a renewable resource because it is available in large quantities and routinely widely cultivated in the world. At present, development of new and effective methods to convert low-grade cellulose into high value-added products is critical. With this Jun Zhang aim, we developed two strategies: All-cellulose nanocomposites reinforced with in situ retained cellulose nanocrystals during selective dissolution of cellulose Chinese Academy of Sciences, China in an IL; and blending low degree of polymerization (DP) cellulose with a small amount of high-DP cellulose. With these two strategies, some low-grade cellulose resources, such as agricultural straw, waste newspapers, and waste cellulose- containing fabrics, were converted into high value-added cellulose-based films. In this talk, I would like to introduce our research progress in this field. Biography Jun Zhang is a Professor of Polymer Science and Materials at CAS Key Laboratory of Engineering Plastics, Institute of Chemistry, Chinese Academy of Sciences (ICCAS). He obtained his PhD degree from Dalian University of Technology of China, in 1999. He has published more than 150 research articles and three book chapters and holds 28 China patents.

Ionic liquid-based green process engineering for co-production of ethylene glycol and dimethyl carbonate
thylene glycol (EG) as one of bulk chemicals and dimethyl carbonate (DMC) as Eenvironmental friendly chemical materials have strategic significance for the basic industries and new industries. The development of green process engineering for coproduction of EG and DMC is highly required as the conventional routes involve either high energy consumption or toxic material. The successful industrial ionic liquid-based green process engineering has several advantages. First, the supported ionic liquid based on synergistic catalytic effect in a fixed bed avoids energy consumption and the loss of catalyst, compared with traditional processes in which the separation of ethylene carbonate and catalyst cost a lot of energy. Second, reactive distillation breaks the equilibrium of the transesterification reaction and converts all ethylene carbonate, thereby improving conversion. This Weiguo Cheng is more straightforward than using a series of fixed bed reactors and ethylene carbonate hydration reactor. Third, energy consumption is reduced (20%~30%) Institute of Process Engineering due to the heat integration system compared with traditional process of the

lternatives to fossil fuels as an energy source are necessary to reach a sustainable tomorrow. A green, renewable and Apromising energy carrier is formic acid that can be decomposed to hydrogen and carbon dioxide. With a hydrogen capacity of 4.3 wt%, formic acid delivers hydrogen that can be converted to electricity in fuel cells. The decomposition of the acid takes place at mild reaction conditions. With heterogeneous palladium catalysts, the dehydrogenation of aqueous formic acid happens at room temperature and ambient pressure with high selectivity of hydrogen and carbon dioxide. Because of the moderate reaction conditions, hydrogen is obtained on-demand and can be converted to energy. The source for sustainable, green and renewable formic acid is the conversion of biomass to aqueous formic acid. With the help of homogeneous catalysts, biological waste is converted to aqueous formic acid that can be used as green energy carrier. However, while decomposing aqueous formic acid to hydrogen and carbon dioxide, heterogeneous palladium catalysts deactivate within a short time scale. Within a few hours, the activity of the catalyst decreases dramatically so that it is necessary to regenerate the catalytic active material. Regenerating the poisoned heterogeneous palladium catalysts is possible so that the precious metal can be reused for the dehydrogenation of aqueous formic acid. By recycling the palladium catalysts, it is feasible to use formic acid as a renewable and green liquid hydrogen storage chemical.

Double-dip approach: Simultaneous acquisition of the dissolution curves of two active ingredients in a binary pharmaceutical dosage form exploiting the opportunities offered by ion selective electrodes Dina A Ahmed1, Mohamed K AbdelRahman2, Hayam Mahmoud Lotfy1 and Soheir Abdel Fattah Weshahy2 1Future University in Egypt, Egypt 2Cairo University, Egypt
cquisition of the dissolution profiles of more than single active ingredient in a multi-component pharmaceutical Aformulation is dominated by utilization of the off-line spectroscopic and chromatographic methods. In this approach, a double-dip green analytical chemistry (GAC) approach with the goal of advancing the in-line potentiometric sensors to their most effective use for simultaneous acquisition of the dissolution curves of two active ingredients in a binary pharmaceutical dosage form, Brufen Flu is adopted. For the proof of concept, two sensitive and selective sensors were developed for the simultaneous determination of the cationic pseudoephedrine (PSE) and the anionic ibuprofen (IBU) drugs to monitor their dissolution profiles without sample pretreatment or derivatization. For the determination of the cationic drug (PSE), sensor I was developed using potassium tetrakis (4-chlorophenyl) borate (KTCPB) as a cationic exchanger, while sensor II was developed for the determination of the anionic IBU using tridodecyl methyl ammonium chloride (TDC) as an anionic exchanger using 2-nitrophenyl octyl ether (2-NPOE) as a plasticizer for both used sensors. The use of these novel sensors not only provides a way for the determination of PSE and IBU in bulk powder, in laboratory mixtures and in combined dosage form but also, permits simultaneous in-line monitoring of their dissolution profiles. The advantages of the newly introduced double-dip approach are highlighted and the merits of these benign real-time analyzers (ISEs) that can deliver equivalent analytical results as HPLC and UV-spectrophotometry, while significantly reducing solvent consumption/waste generation in addition to the manipulation steps are described.

Preparation of activated carbon from olive waste, application as adsorbent for persistent organic pollutants in water Nadia El Ouahedy1, 3, Satu Ojala2, Laurence Pirault-Roy1 and Rachid Brahmi3 1University of Poitiers, France 2University of Oulu, Finland 3University of Chouaib Doukkali, Morocco
n the present study, we have investigated the adsorption, by activated carbon prepared from olive stones, of two pollutants, IBisphenol A, a substance causes a disruption of endocrine systems and ubiquity in the aquatic environment, and diuron, a pesticide detected in groundwater and may reach higher levels than health-based standards. The olive stones were chemically activated and then pyrolysed (thermal treatment under nitrogen). On the other hand, to optimize the preparation method, the effect of the main process parameters (such as activating agent used, impregnation ratio, temperature of pyrolysis step) on the performances of the obtained activated carbons (expressed in terms of adsorption capacity of BPA and diuron and
specific surface area) was studied. The physicochemical properties of the activated carbon prepared were characterized by N2 adsorption/desorption, FTIR, SEM, X-Ray diffraction, CHNS and TGA/DTA. To optimize the adsorption parameters of the activated carbon, preliminary experiments were achieved, such as the effects of solution initial pH and temperature, effect of initial concentration of the pollutants. Promising performances were pointed out as 70% of diuron and 92% of BPA can be removed from aqueous solution for an initial concentration respectively 35 mg/L and 20 mg/L, when the usual concentrations of BPA in environmental waters are in the range of 10 ng/L to 400 μg/L and diuron is around 1 to 600 ng/L. This innovative process is based on valorization of agricultural waste biomass, of which billions of kilograms are produced annually, to low cost but efficient adsorbent that can contribute to environmental remediation.
Biography Nadia El Ouahedy is pursuing her PhD from University of Chouaib Doukkali in Morocco and University of Poitiers in France working on depollution of water by hybrid system as a part of the project PHC Maghreb 2016. She is preparing adsorbents from olive waste from Morocco, such as the charcoal prepared by the hydrothermal carbonization process at Triers University in Germany and activated carbon at University of Poitiers in France and Oulu University in Finland, to apply them for the adsorption of Bisphenol A and Diuron followed by a catalytic oxidation of those pollutants.

Catalytic transformation of 2,5-dimetylfuran to functionalized 2-methyltetrahydrofuran derivatives Jialu Li1, Jonathan Lai2, Marc Pera-Titus2, Stéphane Streiff2, François Jérôme1 and Karine De Oliveira Vigier1 1Université de Poitiers, France 2SOLVAY, China
urans as well as its derivatives are platform chemicals, subsequently transformed to value-added products such as Fpharmaceutical intermediates, fuel additives, bio-based surfactant and solvents. 2,5-dimetylfuran (DMF), a prominent platform molecule, can be obtained via the selective hydrogenation of 5-hydroxymethylfurfural. Despite its outstanding properties, nearly ideal boiling point, high energy density, high research octane number and being immiscible with water, it can also be further valorised. Nonetheless, the amount of furanic derivatives synthesized from DMF is limited due to the complexity of the functionalization of the methyl group. Here, for the first time, we described a convenient catalytic pathway to functionalize methyl group of DMF by using hydrolyzation product 2,5-hexanedione as key an intermediate. A three-step strategy is employed (Figure). Starting from: 2,5-dimethylfuran, hydrolyzation of DMF to hexane-2,5-dione is performed in presence of an acid catalyst; then hexane-2,5-dione reacts with and aldehyde in the presence of a basic catalyst; followed by; a hydrogenation/cyclization by metal support catalyst to obtain methyltetrahydrofuran derivatives. The screening of acid catalysts for the first step and basic-catalysts for the second step was investigated leading to interesting yields to the desired products. Based on these results, the feasibility of one-pot reaction starting directly from 2,5-DMF and aldehydes was demonstrated. The third step (hydrogenation/cyclization) was studied and 80% of the final target product was achieved. A theoretical approach combined with an experimental approach revealed that the reaction temperature is a key parameter in this step. The recyclability of the catalysts in all the three steps was also studied.
