This report presents a cost analysis of Ester-Grade Acrylic Acid (EAA) production from chemical grade (CG) propylene The process examined is a typical propylene oxidation. In this process, propylene passes through a two-stage vapor phase oxidation to generate an acrylic acid-containing gas, from which acrylic acid is recovered via absorption in water. The aqueous acrylic acid solution is purified via light solvent extraction to Ester-grade Acrylic Acid (EAA), which is used in the production of acrylic esters. This report was developed based essentially on the following reference(s): "Acrylic Acid", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Propene, Air Oxidation, Propenoic Acid, Nippon Shokubai, Rohm & Haas, Dow

This report presents a cost analysis of DL-Methionine production from methional and hydrogen cyanide (HCN). The process examined is a typical carbonate process. This process is a multi-step process including: hydantoin intermediate production; reaction of hydantoin with potassium carbonate to produce potassium methioninate; and methioninate conversion to DL-Methionine. This report was developed based essentially on the following reference(s): US Patent 20130231501, issued to Evonik in 2013 Keywords: DLM, 3-Methylmercapto Propionaldehyde, MMP, Methional, Essential Amino Acid, Degussa
This monograph consists of manuscripts submitted by invited speakers who participated in the symposium "Industrial Environmental Chemistry: Waste Minimization in Industrial Processes and Remediation of Hazardous Waste," held March 24-26, 1992, at Texas A&M University. This meeting was the tenth annual international symposium sponsored by the Texas A&M Industry-University Cooperative Chemistry Program (IUCCP). The program was developed by an academic-industrial steering committee consisting of the co-chairmen, Professors Donald T. Sawyer and Arthur E. Martell of the Texas A&M University Chemistry Department, and members appointed by the sponsoring companies: Bernie A. Allen, Jr., Dow Chemical USA; Kirk W. Brown, Texas A&M University; Abraham Clearfield, Texas A&M University; Greg Leyes, Monsanto Company; Jay Warner, Hoechst-Celanese Corporation; Paul M. Zakriski, BF Goodrich Company; and Emile A. Schweikert, Texas A&M University (IUCCP Coordinator). The subject of this conference reflects the interest that has developed in academic institutions and industry for technological solutions to environmental contamination by industrial wastes. Progress is most likely with strategies that minimize waste production from industrial processes. Clearly the key to the protection and preservation of the environment will be through R&D that optimizes chemical processes to minimize or eliminate waste streams. Eleven of the papers are directed to waste minimization. An additional ten papers discuss chemical and biological remediation strategies for hazardous wastes that contaminate soils, sludges, and water.
Chemical reaction engineering is concerned with the exploitation of chemical reactions on a commercial scale. It's goal is the successful design and operation of chemical reactors. This text emphasizes qualitative arguments, simple design methods, graphical procedures, and frequent comparison of capabilities of the major reactor types. Simple ideas are treated first, and are then extended to the more complex.
"Science tends to generalize, and generaliza tions mean simplifications . . . . And generaliza tions are also more satisfying to the mind than details. Of course, details and generalizations must be in proper balance: Generalizations can be reached only from details, while it is the generalization which gives value and interest to the detail:' . . . (A. Szent-Gyorgy, Science 1964) The first edition of this book, published in German as Tabak abhiingigkeit in 2001, was prompted by the fact that no single volume was available in Germany or elsewhere summarising the adverse repercussions of cigarette smoking on human health. As far as my own research was able to ascertain, the last comprehensive work dealing with this subject was writ ten in Germany by the Dresden internist, F. Lickint, whose Tabak und Organismus was published in 1939 by the Hip pokrates-Verlag. All subsequent monographs in this field have tended to focus on detailed aspects, and there has been no shortage of publications on subjects such as how smokers can quit smoking, healthy eating for smokers etc. Friends and colleagues abroad have urged me to prepare an English language version of Tabakabhiingigkeit. In gladly complying with this suggestion, I have intentionally prepared an up dated and slightly enlarged new edition, taking account of the rapidly proliferating literature on the subject up to the start of 2002. The harmful sequelae of smoking are played down by politicians in many industrialised countries, including Ger many.
The practice of biotechnology, though different in style, scale and substance in globalizing science for development involves all countries. Investment in biotechnology in the industrialised, the developing, and the least developed countries, is now amongst the widely accepted avenues being used for economie development. The simple utilization of kefir technology, the detoxification of injurious chemical pesticides e.g. parathion, the genetic tailoring of new crops, and the production of a first of a kind of biopharmaceuticals illustrate the global scope and content of biotechnology research endeavour and effort. In the developing and least developed nations, and in which the 9 most populous countries· are encountered, problems concerning management of the environment, food security, conservation of human health resources and capacity building are important factors that influence the path to sustainable development. Long-term use of biotechnology in the agricultural, food, energy and health sectors is expected to yield a windfall of economic, environmental and social benefits. Already the prototypes of new medicines and of prescription fruit vaccines are available. Gene based agriculture and medieine is increasingly being adopted and accepted. Emerging trends and practices are reflected in the designing of more efficient bioprocesses, and in new research in enzyme and fermentation technology, in the bioconversion of agro industrial residues into bio-utility products, in animal healthcare, and in the bioremediation and medical biotechnologies. Indeed, with each new day, new horizons in biotechnology beckon.
A useful guide to the fundamentals and applications of deep eutectic solvents Deep Eutectic Solvents contains a comprehensive review of the use of deep eutectic solvents (DESs) as an environmentally benign alternative reaction media for chemical transformations and processes. The contributors cover a range of topics including synthesis, structure, properties, toxicity and biodegradability of DESs. The book also explores myriad applications in various disciplines, such as organic synthesis and (bio)catalysis, electrochemistry, extraction, analytical chemistry, polymerizations, (nano)materials preparation, biomass processing, and gas adsorption. The book is aimed at organic chemists, catalytic chemists, pharmaceutical chemists, biochemists, electrochemists, and others involved in the design of eco-friendly reactions and processes. This important book: -Explores the promise of DESs as an environmentally benign alternative to hazardous organic solvents -Covers the synthesis, structure, properties (incl. toxicity) as well as a wide range of applications -Offers a springboard for stimulating critical discussion and encouraging further advances in the field Deep Eutectic Solvents is an interdisciplinary resource for researchers in academia and industry interested in the many uses of DESs as an environmentally benign alternative reaction media.
