Bimetallic Catalyst Catalyzed Carbonylation of Methanol to Acetic Acid

The interaction between the metals of the bimetallic catalyst and the structure of the bridged dimer can effectively reduce the steric hindrance effect and help speed up the reaction rate while ensuring the stability of the catalyst. X-ray photoelectron spectroscopy (XPS) results show that rhodium accepts electrons from chlorine, thereby increasing the electron-rich nature of rhodium and improving the catalytic activity. This promotes the nucleophilic reaction of the catalyst with methyl iodide and reduces the reaction energy barrier. The methanol carbonylation performance of the Rh/Ru catalyst was evaluated, and the results show that the conversion rate of methyl acetate and the yield of acetic acid are 96.0% under certain conditions. Furthermore, during the catalysis, no precipitate is formed and the amount of water is greatly reduced. -

Production of Malonic Acid through the Fermentation of Glucose Abstract The overall process to produce malonic acid has not drastically changed in the past 50 years. The current process is damaging to the environment and costly, requiring high market prices. Lygos, Inc., a lab in Berkeley, California, has published a patent describing a way to produce malonic acid through the biological fermentation of genetically modified easty cells. This proposed technology is appealing as it is both better for the environment and economically friendly. For the process discussed in this report, genetically modified Pichia Kudriavzevii yeast cells will be purchased from the Lygos lab along with the negotiation of exclusive licensing rights to the technology. The cells will be grown in fermentation vessels, while being constantly fed oxygen, glucose and fermentation media. The cells will excrete malonic acid in the 101 hour fermentation process. -
Chapter -1 Introduction, Review of Literature And
CHAPTER -1 INTRODUCTION, REVIEW OF LITERATURE AND SCOPE OF THE PRESENT WORK 1 INTRODUCTION The heterocycles play an important part in the metabolism of all living cells and find important applications in industry.1 Among these important substances, such vitamins and coenzymes precursors as thiamine, riboflavin, nicotinic acid, adenine, biotin, vitamin Bi2, vitamin E, photosynthesizing pigment chlorophyll, the oxygen-transporting pigment haemoglobin, the purine and pyrimidine which are the components of the nucleic acids, and their metabolic products such as uric acid, allantoin, and alloxan to the amino-acids like histidine, tryptophan, proline, and the harmones such as kinetin, zeatin, heteroauxin and histamine contain heterocyclic ring system in them. Many of the drugs, natural as well as synthetic, which are in regular use are heterocyclic compounds. The several natural drugs such as alkaloids, the cardiac glycosides and antibiotics such as penicillin contain heterocyclic ring in them. Some other synthetic heterocyclic compounds are numerous and include barbiturates, thiouracil, carbimazole, 9-aminoacridine, 8-hydroxyquinoline, and vasoprassor modifiers. Polyvinylpyrrolidone are used as a replacement for serum lost in haemorrhage and shock. Many pesticides and weed killers such as paraquat, diquat and simazine; insecticides such as rotenone, diazinon, menazon; anthelminitics such as phenothiazine, thiabendazoles; rodenticides such as warfarin are heterocyclic compounds. The heterocycles are acting as the antidotes for poisoning due to the phosphorus insecticides, such as pyridine-2-aldoxime methiodide. The current use of the heterocycles in drugs and pesticides is due to the high resistance of heterocyclic substances to biological degradation. In addition to the drug value the synthetic heterocyclic compounds acts as chemotherapeutic agents, dyestuffs and co-polymers. -
Author's Response
We thank the referees for their additional comments. We have revised the manuscript following the referees’ suggestions. You can find answers to the referee comments (in italics) below with additions to the manuscript and supplement text (in bold). Referee #1 The authors have provided responses to the questions, comments and issues pointed out by both referees. They have carried out 5 additional calculations and have modified the manuscript to account for suggested changes, where applicable. For this second round of reviews of this technical note, I will focus on the replies and manuscript sections with changes. Most of the issues raised in the first round have been addressed well. I have found a few issues to be further addressed before this manuscript is finalized for publication. The line numbers used in the following comments are those from the revised manuscript (ms version 3). 10 line 300: Regarding the acid dissociation reaction (R2) notation for oxalic acid, it is a bit odd that you write the reaction − + using HA for the acid, given that oxalic acid is a diacid. It would be better to write the reaction as H2A+H2O = HA +H3O and perhaps also list the second dissociation reaction involving HA− (even if not considered by COSMO-RS-DARE). Further along these lines, from the main text alone it remains unclear whether both acid dissociation reactions were considered in the 15 model or not; should be clarified. Author’s response: Thank you for this suggestion. We have added the second deprotonation reaction to the equilibrium reaction (R2). We also mention in the text why only the first deprotonation was considered. -
Surface Characterization and Reactivity of Methylammionium Lead Iodide
Surface Characterization and Reactivity of Methylammionium Lead Iodide by Kenneth Zielinski A Thesis Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Master of Science Degree in Chemistry October 2018 APPROVED: Assistant Professor Ronald L. Grimm, Advisor Associate Professor N. Aaron Deskins, Committee Member Associate Teaching Professor Christopher Lambert, Committee Member Associate Professor Shawn Burdette, Committee Member Professor Arne Gericke, Department Head 1 Abstract We quantify the chemical species present at and reactivity of the tetragonal (100) face of single-crystal methylammonium lead iodide, MAPbI3(100). MAPbI3 is an ABX3 perovskite, experiments utilized the orthogonal reactivity of the A+-site cation, the B2+-site – cation, and the X -site halide anion. Ambient-pressure exposure to BF3 solutions probe the reactivity of interfacial halides. Reactions with p-trifluoromethylanilinium chloride probe the exchange reactivity of the A+-site cation. The ligand 4,4’-bis(trifluoromethyl)- 2,2’-bipyridine probe for interfacial B2+-site cations. Fluorine features in x-ray photoelectron spectroscopy (XPS) quantify reaction extents with each solution-phase species. XP spectra reveals adsorption of BF3 indicating surface-available halide anions on tetragonal MAPbI3(100) and preliminary examinations on the (112), (110), and thin- film surfaces. Temperature-programmed desorption (TPD) established a ~200 kJ mol–1 desorption activation energy from tetragonal MAPbI3(100). Adsorption of the fluorinated anilinium cation includes no concomitant adsorption of chlorine as revealed by the absence of Cl 2p features within the limits of XPS detection on the tetragonal (100) and (112) faces with no discernable exchange in preliminary experiments on tetragonal (110). -

Chemical Compatibility Guide - Polyethylene for Ultratech Spill Containment Products
Chemical Compatibility Guide - Polyethylene For UltraTech Spill Containment Products This listing was prepared to provide guidance to the chemical compatibility When considering an UltraTech polyethylene product for use in secondary of UltraTech Spill Containment Products which are manufactured and containment applications, it is important to note that most secondary constructed of a molded polyethylene. containment products are designed to hold leaked chemicals for only hours, Polyethylene is susceptible to attack by some chemicals which may cause a day, at most a week. stress cracking, swelling, oxidation or may permeate the polyethylene. These secondary containment units would then be cleaned of any chemical. These reactions may reduce the physical properties of polyethylene. In these short term applications, a greater variety of chemicals may be used with the polyethylene since the exposure time of the chemical to the polyethylene is limited. A = Suitable for long term storage at 100 degrees Fahrenheit or less. B = Suitable for short term storage less than one year. C = Do NOT store these chemicals in UltraTech containment products. User testing may prove some of these chemicals are suitable for secondary containment applications with an exposure time of one week or less.
