Download or read book Phosgenations written by Livius Cotarca and published by John Wiley & Sons. This book was released on 2006-03-06 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this manual, the authors compare the range of applications for phosgene with that of the alternative compounds, dealing in detail with the possible uses of diphosgene, triphosgene, carbon dioxide, organic carbonates, oxalylchloride and many other alternative materials used in synthesis. However, they clearly point out those cases where phosgene continues to have the advantage. The result is a mine of information for synthetic chemists working in industry and academia faced with the question of where the toxic phosgene can be replaced by an unproblematic compound - including the safety phosgenation.
Download or read book Phosgene written by T.A. Ryan and published by Elsevier. This book was released on 1996-05-24 with total page 929 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosgene, COCl2 is a C1 chemical of major industrial importance. The annual production, worldwide, is more than 1 million tons; 90% of which is used in the manufacture of isocyanates and of polyurethane and polycarbonate resins. Phosgene is also extensively used as a synthetic reagent in organic chemistry, in particular in the preparation of acyl chlorides, chloroformate esters, organic carbonates and carbamoyl chlorides. Although more than 7000 papers have appeared on phosgene and some 1000 papers on its analogues, this is the first book on these interesting chemicals. It presents a critical treatise of phosgene, ranging from its discovery and subsequent use as a war gas to some potential applications of the material into the 21st century. It includes chapters on biological effects and industrial hygiene; on synthesis, formation and manufacture; analysis, uses, environmental effects, and physical and thermodynamic properties. Reactions with organic and inorganic materials are described. Four of the seventeen chapters are devoted to a description of the carbonyl halides (especially carbonyl difluoride) related to phosgene, and a special section deals collectively with the electronic structures of carbonyl halide molecules. Featuring the first-ever comprehensive discussion of the medical effects of phosgene poisoning and the most modern methods of treating exposure victims, the book will be of interest to historians and militarists and those working in the chemical industries (heavy chemicals, agricultural and pharmaceutical), university libraries, hospitals, medical research centres, museums, environmental research centres, poison units and health and safety institutions world-wide.
Download or read book The Use and Storage of Methyl Isocyanate MIC at Bayer CropScience written by National Research Council and published by National Academies Press. This book was released on 2012-07-31 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of hazardous chemicals such as methyl isocyanate can be a significant concern to the residents of communities adjacent to chemical facilities, but is often an integral part of the chemical manufacturing process. In order to ensure that chemical manufacturing takes place in a manner that is safe for workers, members of the local community, and the environment, the philosophy of inherently safer processing can be used to identify opportunities to eliminate or reduce the hazards associated with chemical processing. However, the concepts of inherently safer process analysis have not yet been adopted in all chemical manufacturing plants. The Use and Storage of Methyl Isocyanate (MIC) at Bayer CropScience presents a possible framework to help plant managers choose between alternative processing options-considering factors such as environmental impact and product yield as well as safety- to develop a chemical manufacturing system. In 2008, an explosion at the Bayer CropScience chemical production plant in Institute, West Virginia, resulted in the deaths of two employees, a fire within the production unit, and extensive damage to nearby structures. The accident drew renewed attention to the fact that the Bayer facility manufactured and stores methyl isocyanate, or MIC - a volatile, highly toxic chemical used in the production of carbamate pesticides and the agent responsible for thousands of death in Bhopal, India, in 1984. In the Institute accident, debris from the blast hit the shield surrounding a MIC storage tank, and although the container was not damaged, an investigation by the U.S. Chemical Safety and Hazard Investigation Board found that the debris could have struck a relief valve vent pipe and cause the release of MIC to the atmosphere. The Board's investigation also highlighted a number of weaknesses in the Bayer facility's emergency response systems. In light of these concerns, the Board requested the National Research Council convene a committee of independent experts to write a report that examines the use and storage of MIC at the Bayer facility. The Use and Storage of Methyl Isocyanate (MIC) at Bayer CropScience also evaluates the analyses on alternative production methods for MIC and carbamate pesticides preformed by Bayer and the previous owners of the facility.

Download or read book Industrial Arene Chemistry written by Jacques Mortier and published by John Wiley & Sons. This book was released on 2023-03-17 with total page 2751 pages. Available in PDF, EPUB and Kindle. Book excerpt: Industrial Arene Chemistry Explore the wide array of uses for aromatic hydrocarbons in this comprehensive reference Aromatics are a class of compounds—normally but not exclusively organic—which tend to be produced as by-products of various industrial processes. Their importance as petrochemical materials in themselves, along with the range of inter-relations between different aromatic chemicals, creates a complex and opportunity-filled market for aromatics. Industrial Arene Chemistry provides a thorough look at the conventional techniques required to use and produce these aromatic hydrocarbons. Beginning with an overview of the global aromatic market—including, but not limited to, manufacturers, markets of BTX, and downstream functional aromatics, aromatics derived from renewable sources, and economic forecasts—the book will also explore the impact shifting environmental factors will have on the future of aromatic chemistry. The text further explores BTX production processes differentiated according to the raw materials used. Importantly, this will establish the importance and growth of the biobased chemical industry. Industrial Arene Chemistry readers will also find: Case studies that describe major elements of specific technologies prototyped by contributors/companies as part of ongoing market development efforts Process chapters that include summaries of the conventional techniques and a more detailed discussion of recent high-impact studies Recent advances in conventional aromatic reactions, including alkylation, acylation and carboxylation, hydrogenation/reduction, oxidation, nitration/amination, sulfonation, and halogenation Industrial Arene Chemistry is a useful reference for chemists and chemical engineers who work with aromatics.

Download or read book Polyurethane Elastomers written by Cristina Prisacariu and published by Springer Science & Business Media. This book was released on 2011-07-03 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive account of the physical / mechanical behaviour of polyurethanes (PU ́s) elastomers, films and blends of variable crystallinity. Aspects covered include the elasticity and inelasticity of amorphous to crystalline PUs, in relation to their sensitivity to chemical and physical structure. A study is made of how aspects of the constitutive responses of PUs vary with composition: the polyaddition procedure, the hard segment, soft segment and chain extender (diols and diamines) are varied systematically in a large number of systems of model and novel crosslinked andthermoplastic PUs. Results will be related to: microstructural changes, on the basis of evidence from x-ray scattering (SAXS and WAXS), and also dynamic mechanical analyses (DMA), differential scanning calorimetry (DSC) and IR dichroism. Inelastic effects will be investigated also by including quantitative correlations between the magnitude of the Mullins effect and the fractional energy dissipation by hysteresis under cyclic straining, giving common relations approached by all the materials studied. A major structural feature explored is the relationship between the nature of the hard segment (crystallising or not) and that of the soft segments. Crystallinity has been sometimes observed in the commercial PUs hard phase but this is usually limited to only a few percent for most hard segment structures when solidified from the melt. One particular diisocyanate, 4,4’-dibenzyl diisocyanate (DBDI) that, in the presence of suitable chain extenders ( diols or diamines), gives rise to significant degrees of crystallinity [i-iii] and this is included in the present work. Understanding the reaction pathways involved, in resolving the subtle morphological evolution at the nanometre level, and capturing mathematically the complex, large-deformation nonlinear viscoelastic mechanical behaviour are assumed to bring new important insights in the world basic research in polyurethanes and towards applied industrial research in this area.
