  • Bio-Based Chemicals from Renewable Biomass for Integrated Biorefineries
    energies Review Bio-Based Chemicals from Renewable Biomass for Integrated Biorefineries Kirtika Kohli 1 , Ravindra Prajapati 2 and Brajendra K. Sharma 1,* 1 Prairie Research Institute—Illinois Sustainable Technology Center, University of Illinois, Urbana Champaign, IL 61820, USA; [email protected] 2 Conversions & Catalysis Division, CSIR-Indian Institute of Petroleum, Dehradun, Uttarakhand 248005, India; [email protected] * Correspondence: [email protected] Received: 10 December 2018; Accepted: 4 January 2019; Published: 13 January 2019 Abstract: The production of chemicals from biomass, a renewable feedstock, is highly desirable in replacing petrochemicals to make biorefineries more economical. The best approach to compete with fossil-based refineries is the upgradation of biomass in integrated biorefineries. The integrated biorefineries employed various biomass feedstocks and conversion technologies to produce biofuels and bio-based chemicals. Bio-based chemicals can help to replace a large fraction of industrial chemicals and materials from fossil resources. Biomass-derived chemicals, such as 5-hydroxymethylfurfural (5-HMF), levulinic acid, furfurals, sugar alcohols, lactic acid, succinic acid, and phenols, are considered platform chemicals. These platform chemicals can be further used for the production of a variety of important chemicals on an industrial scale. However, current industrial production relies on relatively old and inefficient strategies and low production yields, which have decreased their competitiveness with fossil-based alternatives. The aim of the presented review is to provide a survey of past and current strategies used to achieve a sustainable conversion of biomass to platform chemicals. This review provides an overview of the chemicals obtained, based on the major components of lignocellulosic biomass, sugars, and lignin.

  • Sugar Alcohols a Sugar Alcohol Is a Kind of Alcohol Prepared from Sugars
    Sweeteners, Good, Bad, or Something even Worse. (Part 8) These are Low calorie sweeteners - not non-calorie sweeteners Sugar Alcohols A sugar alcohol is a kind of alcohol prepared from sugars. These organic compounds are a class of polyols, also called polyhydric alcohol, polyalcohol, or glycitol. They are white, water-soluble solids that occur naturally and are used widely in the food industry as thickeners and sweeteners. In commercial foodstuffs, sugar alcohols are commonly used in place of table sugar (sucrose), often in combination with high intensity artificial sweeteners to counter the low sweetness of the sugar alcohols. Unlike sugars, sugar alcohols do not contribute to the formation of tooth cavities. Common Sugar Alcohols Arabitol, Erythritol, Ethylene glycol, Fucitol, Galactitol, Glycerol, Hydrogenated Starch – Hydrolysate (HSH), Iditol, Inositol, Isomalt, Lactitol, Maltitol, Maltotetraitol, Maltotriitol, Mannitol, Methanol, Polyglycitol, Polydextrose, Ribitol, Sorbitol, Threitol, Volemitol, Xylitol, Of these, xylitol is perhaps the most popular due to its similarity to sucrose in visual appearance and sweetness. Sugar alcohols do not contribute to tooth decay. However, consumption of sugar alcohols does affect blood sugar levels, although less than that of "regular" sugar (sucrose). Sugar alcohols may also cause bloating and diarrhea when consumed in excessive amounts. Erythritol Also labeled as: Sugar alcohol Zerose ZSweet Erythritol is a sugar alcohol (or polyol) that has been approved for use as a food additive in the United States and throughout much of the world. It was discovered in 1848 by British chemist John Stenhouse. It occurs naturally in some fruits and fermented foods. At the industrial level, it is produced from glucose by fermentation with a yeast, Moniliella pollinis.

Peter Abelard, Paris, 1122 Abstract This thesis concerns an investigation into the generation and reactivity of organozinc carbenoids, from both a practical and mechanistic standpoint, using the reductive deoxygenation of carbonyl compounds with zinc and a silicon electrophile. The first introductory chapter is a review of organozinc carbenoids in synthesis. The second chapter opens with an overview of the development of the reductive deoxygenation of carbonyl compounds with zinc and a silicon electrophile since its inception in 1973. The factors influencing the generation of the zinc carbenoid are then investigated using a control reaction, and discussed.

Ona,2 Yoshihiro Kojima3 and Hitoki Matsuda2 1 Mitsubishi Chemical Group Science and Technology Research Center, Toho-Cho 1, Yokkaichi, Mie 540-8530, Japan, [email protected] 2 Department of Chemical Engineering, Nagoya University, Furo-Cho, Chikusa, Aichi 464-8630, Japan 3 Research Center for Advanced Waste and Emission Management, Nagoya University, Furo-Cho, Chikusa, Aichi 464-8630, Japan ABSTRACT This study focused on polyalcohols as phase change material, which stores a large amount of latent heat at high temperature. D-Threitol, which is an isomer of meso-Erythritol, was studied to obtain its phase change characteristics by means of DSC analysis and a lab-scale heating and cooling apparatus. Usability of D-Threitol as phase change material was evaluated by comparison with other polyalocohols. It was found that D-Threitol started to melt at around 90 degrees C with a relatively large latent heat of 225 kJ/kg. On the other hand, D-Threitol started solidification when the temperature was cooled between at 40 degrees C and 46 degrees C, indicated by a rapid rise to 89 degrees C in a lab-scale heating and cooling apparatus. It was then considered that D-Threitol was applicable as an environmental-friendly PCM for a hot water supply. KEYWORDS Phase change materials, Polyalcohols, Threitol INTRODUCTION Latent heat storage by Phase Change Materials (PCMs) has the advantage to store and release a relatively large quantity of heat in a constant narrow temperature range during phase change.

For my Family Abstract A detailed understanding of the human immune system is crucial for developing novel pharmaceuticals to fight a range of diseases. The glycolipid α-galactosyl ceramide, α-GalCer, has been shown to stimulate the proliferation of murine spleen cells and activate the immune system. Stimulation occurs through binding of the glycolipid to the protein CD1d. Subsequent presentation of the CD1d−glycolipid complex to invariant Natural Killer T cells (iNKT cells) initiates the proliferation of a host of cytokines leading to an immune response. The therapeutic potential of α-GalCer is currently being explored; however the induction of both Th1 and Th2 cytokines by this agent is likely to limit its therapeutic application. The crystal structure of human CD1d in complex with α- GalCer reveals a key hydrogen bond between the N-H of the amide group of the glycolipid and the side-chain O-H of Thr 154 located on the α2 helix of the CD1d molecule; however, the carbonyl group of the amide is not directly involved in binding.

This sugar­ alcohol, a substance which has not been reported in hibernating insects, decreased rapidly when these insects ceased their hibernation. Introduction Since the first discovery of glycerol and so rbitol accumulated in diapause eggs of Bambyx mari (1), the prevalence of glycerol accumulated in hibernat­ ing insects has been proved (5). Concomitantly, accumulation of two other substances, trehalose (4) and threitol (2), were also discovered in some insects. H ere the occurrence of another sugar-alcohol, inositol, accumulated in hiber­ nating adults of some beetles is preliminarily reported, leaving detailed ac" counts. Before going further, I wish to express my sincere thanks to Prof. Sh6ichi F. Sakagami and Dr. Ichir6 Takehara for their reading through the manuscript. Cordial thanks are also due to Dr. Kimio S himada for his kind advice throughout this study.

  • Sugar Matrix
    Based on perfact’s database holding ingredients for over 250,000 products, we found that almost 300 names for sugar that appear on food labels aren’t covered by the “56 names of sugar” and SugarScience’s 61 names of sugar. The exact number depends on how one counts. This document aims to be a basis to help draw the lines between what should be considered “sugar” within the scope of those lists – and what shouldn’t.

Received: 25 November 2020; Accepted: 9 December 2020; Published: 12 December 2020 Abstract: Bio-based polyol polyesters are biodegradable elastomers having potential utility in soft tissue engineering. This class of polymers can serve a wide range of biomedical applications. Materials based on these polymers are inherently susceptible to degradation during the period of implantation. Factors that influence the physicochemical properties of polyol polyesters might be useful in achieving a balance between durability and biodegradability. The characterization of these polyol polyesters, together with recent comparative studies involving creative synthesis, mechanical testing, and degradation, have revealed many of their molecular-level differences. The impact of the polyol component on the properties of these bio-based polyesters and the optimal reaction conditions for their synthesis are only now beginning to be resolved.
