Book Description
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.

Book Description
MDI and TDI are polymer building blocks with a wide range of applications in industry. Both are used in large quantities and can be found in a wide variety of industries and applications. As their use will often involve large numbers of workers they are also subject to stringent health and safety regulations. This book covers all the important topics concerning MDI and TDI and provides comprehensive coverage on the health and environmental science associated with these. Considering the risk management of both substances this is the first book to offer comprehensive discussion of health and environmental issues and includes * insights from academic, regulatory, and industrial experts * numerous photographs, spectra, tables, and graphs * additional information on physical properties and analysis * Considers the risk management of these two diisocyanates Addressing their use throughout industry this title presents an essential source of information for occupational physicians, industrial hygiene professionals, polyurethane producers, environmental scientists, chemical analysts and regulators.

Book Description
Comprehensive knowledge on the preparation, characterization, and applications of polymer nanocomposites Chemical Physics of Polymer Nanocomposites examines the state of the art in preparation, processing, characterizing, and applying a wide range of polymer nanocomposites, elucidating nanofiller/polymer interactions, nanofiller dispersion, distribution, filler-filler interactions, and interface properties, with a particular focus on the rheology of this important class of materials. The dependence of the rheological properties on the preparation techniques is discussed in detail, complemented by an overview of the processing approaches using conventional and micro injection molding, extrusion, compression molding, film blowing, pultrusion, and resin transfer molding. The book covers the latest understanding and accomplishments on polymer composites and presents the huge variety of this materials class. Practice-oriented with industry relevance, it also reviews preparation, characterization, morphology, properties, applications, sustainability, and recyclability. The topics covered in Chemical Physics of Polymer Nanocomposites include: Classification of nano fillers, nano-objects, nanomaterials, and polymer nanocomposites based on chemical nature and identity, and synthesis and characterization of nanoparticles General manufacturing methods and processes, including melt and shear mixing manufacturing of polymer nanocomposites 1D nano fillers and polymer nanocomposites, including polymer nanocomposites based on graphite nanoplatelets (GNP) and amphiphilic graphene platelets Polymer nanocomposites based on nano chitin, starch, and lignin, gold nanowires, titanium dioxide, and graphene and graphene oxide Chemical Physics of Polymer Nanocomposites is an essential resource for materials scientists, polymer chemists, chemical engineers, and engineering scientists in industry.

Book Description
A practical handbook rather than merely a chemistry reference, Szycher's Handbook of Polyurethanes, Second Edition offers an easy-to-follow compilation of crucial new information on polyurethane technology, which is irreplaceable in a wide range of applications. This new edition of a bestseller is an invaluable reference for technologists, marketers, suppliers, and academicians who require cutting-edge, commercially valuable data on the most advanced uses for polyurethane, one of the most important and complex specialty polymers. internationally recognized expert Dr. Michael Szycher updates his bestselling industry "bible" With seven entirely new chapters and five that are revised and updated, this book summarizes vital contents from U.S. patent literature—one of the most comprehensive sources of up-to-date technical information. These patents illustrate the most useful technology discovered by corporations, universities, and independent inventors. Because of the wealth of information they contain, this handbook features many full-text patents, which are carefully selected to best illustrate the complex principles involved in polyurethane chemistry and technology. Features of this landmark reference include: Hundreds of practical formulations Discussion of the polyurethane history, key terms, and commercial importance An in-depth survey of patent literature Useful stoichiometric calculations The latest "green" chemistry applications A complete assessment of medical-grade polyurethane technology Not biased toward any one supplier’s expertise, this special reference uses a simplified language and layout and provides extensive study questions after each chapter. It presents rich technical and historical descriptions of all major polyurethanes and updated sections on medical and biological applications. These features help readers better understand developmental, chemical, application, and commercial aspects of the subject.
