Available in PDF, EPUB and Kindle. Book excerpt: Natural and Synthetic Waxes A compilation of all relevant information for the production and use of waxes in technical applications Waxes are among the oldest organic substances used by mankind. Before all others, beeswax is known to have played a role in human history for thousands of years. But over time, many other wax species have been detected and exploited, and prepared for different utilizations. Today, we possess knowledge of a great variety of different types of waxes. Unfortunately, there still is no broadly accepted definition of a wax: for the relatively few wax chemists, waxes are usually defined by their physico-chemical properties more than by their chemical constitution. Waxes are not uniform but oligomeric and polymeric substances, not simply describable with a chemical formula. The realm of waxes encompasses fully or partly natural, refined, partly or fully synthetic products, which can be extended by “wax-like” products which do not fulfil all definition criteria. Waxes are offered in different forms like pellets, granules, powders, or micropowders. Their number of technical applications runs into thousands. However, waxes in most cases are just adjuvants or additives, and with few exceptions like candles not known to a broader public. Only few publications over the last decades tried to present a more comprehensive overview of heir chemistry, chemical composition, their physical and analytical properties, their applications, and their sometimes astonishing history. Based on personal experience and expertise, the authors intend to present an overview on the main classes of waxes, their origin, history, future, and potential fate. Economical aspects like market size and development, ecological impacts and challenges, and regulatory issues are also addressed. Waxes are indispensable products in everyday life and in industry and technology, though mostly not even visible or distinguishable to experts. They deserve more than the role of a “poor cousin” in chemistry and technology.

Download or read book Handbook of Lubrication and Tribology written by Robert W. Bruce and published by CRC Press. This book was released on 2012-07-06 with total page 1173 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the best-selling first edition, the growing price and environmental cost of energy have increased the significance of tribology. Handbook of Lubrication and Tribology, Volume II: Theory and Design, Second Edition demonstrates how the principles of tribology can address cost savings, energy conservation, and environmental protection. This second edition provides a thorough treatment of established knowledge and practices, along with detailed references for further study. Written by the foremost experts in the field, the book is divided into four sections. The first reviews the basic principles of tribology, wear mechanisms, and modes of lubrication. The second section covers the full range of lubricants/coolants, including mineral oil, synthetic fluids, and water-based fluids. In the third section, the contributors describe many wear- and friction-reducing materials and treatments, which are currently the fastest growing areas of tribology, with announcements of new coatings, better performance, and new vendors being made every month. The final section presents components, equipment, and designs commonly found in tribological systems. It also examines specific industrial areas and their processes. Sponsored by the Society of Tribologists and Lubrication Engineers, this handbook incorporates up-to-date, peer-reviewed information for tackling tribological problems and improving lubricants and tribological systems. The book shows how the proper use of generally accepted tribological practices can save money, conserve energy, and protect the environment.

Download or read book Handbook of Chemical Risk Assessment written by Ronald Eisler and published by CRC Press. This book was released on 2000-04-12 with total page 792 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written over a period of 17 years, the Handbook of Chemical Risk Assessment exhaustively examines and analyzes the world literature on chemicals entering the environment from human activities. The three volumes cover chemicals recommended by environmental specialists of the U.S. Fish and Wildlife Service and other resource managers. The choices were based on the real or potential impact of each contaminant and on the knowledge available about their mitigation. The information for each chemical includes source and use; physical, chemical, and metabolic properties; concentrations in field collections of abiotic materials and living organisms; deficiency effects; lethal and sublethal effects; and proposed regulatory criteria for the protection of human health and sensitive natural resources. Each chapter selectively reviews and synthesizes the technical literature on a specific priority contaminant and its effects on the environment. Successful risk assessment relies heavily on extensive and well-documented databases. They often include too much - or too little - information about too many chemicals. Of the hundreds of thousands of chemicals discharged into the environment, only a small number have sufficient information to attempt preliminary risk assessment. Sold only as a three volume set, the Handbook of Chemical Risk Assessment provides you with the exact amount of information you need in a single resource.

Download or read book An Introduction to Industrial Chemistry written by C.A. Heaton and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: to the Third Edition Following the success of the first two editions of this book in which the core subject matter has been retained, we have taken the opportunity to add substantial new material, including an additional chapter on that most important activity of the chemical industry, research and development. Topical items such as quality, safety and environmental issues also receive enhanced coverage. The team of authors for this edition comprises both those revising and updating their chapters and some new ones. The latter's different approach to the subject matter is reflected in the new titles: Organisational Structures - A Story of Evolution (chapter 5) and Environmental Impact of the Chemical Industry (chapter 9). The chapter on Energy retains its original title but different approach of the new authors is evident. We have updated statistics and tables wherever possible and expanded the index. We hope readers find the brief 'pen pictures' of authors to be interesting. It is worth stressing again that this book is designed to be used with its companion volume - The Chemical Industry, 2nd Edition, ed. Alan Heaton (referred to as Volume 2) - for a complete introduction to the chemical industry. Thanks are due to all contributors and to my wife Joy for typing my contributions.

This book was released on 2007-08-08 with total page 987 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thousands of inorganic and organic chemicals and their metabolites enter the biosphere daily as a direct result of human activities. Many of these chemicals have serious consequences on sensitive species of natural resources, crops, livestock, and public health. The most hazardous of these were identified by a panel of environmental specialists from the U.S. Fish and Wildlife Service; these chemicals are the focus of this encyclopedia. For each priority group of chemicals, information is presented on sources, uses, physical and chemical properties, tissue concentrations in field collections and their significance, lethal and sublethal effects under controlled conditions. This includes effects on survival, growth, reproduction, metabolism, carcinogenicity, teratogenicity, and mutagenicity - and proposed regulatory criteria for the protection of sensitive natural resources, crops, livestock, and human health. Taxonomic groups of natural resources covered include terrestrial and aquatic plants and invertebrates, fishes, amphibians, reptiles, birds, and mammals. * The only product that centers on the most hazardous environmental chemicals to sensitive natural resources * The only single volume compendium on the subject, allowing ease in consulting * Written by a noted national and international authority on chemical risk assessment to living organisms
