Book Description
The organic molecules that are used, particularly in the areas of pharmacy and agrochemicals, are becoming more and more complex both in their chemical nature and spacial configuration. A complex molecular structure is inevitably fragile; it cannot be produced under severe conditions (in particular high pressure and temperature). In addition there is a problem of the scale-up of a product from the laboratory to the industrial scale. The control of the reactivity, selectivity, and yield and the use of sufficiently mild industrial conditions are all factors that must be taken into account by industrial chemists. Amongst the tools giving controllable reactivity, selectivity, and relatively mild reaction conditions is bromine. The organic chemistry of bromine sometimes gives surprising selectivities compared to those of chlorine.This volume which is based on Orgabrom '93, brings together the main contributions presented at this event.

Amongst the tools giving controllable reactivity, selectivity, and relatively mild reaction conditions is bromine. The organic chemistry of bromine sometimes gives surprising selectivities compared to those of chlorine. This volume is based on the first international symposium on the chemistry of organobromine compounds and their uses, Orgabrom '89, organized by the Alsace-Mulhouse Section of the Societe Francaise de Chimie in association with Rhone-Poulenc and Potasse et Produits Chimiques. It brings together the main contributions presented at this event.This was a highly successful international gathering for both industry and academia, affording chemists from over twenty different countries the opportunity to compare their experiments and results. The book will constitute a valuable reference document on the chemistry of bromine and its organic derivatives.

Book Description
The development of organic intermediates requires high performance and original technologies. This book reviews recent work on some fifteen basic technologies in intermediates development including; hydrogenation, fluorination, chlorination, nitration, enzymatic catalysis, hydroxylation, alkylation, carboxylation and the Friedel Crafts reaction. Problems and industrial constraints involved in industrial development are highlighted from a research viewpoint and new technologies with potential for use in industry, particularly catalyst-based technologies clean chemical processes, are described. A chapter dealing with reviews on sodium amidure and polymerisation inhibitors is included.

Book Description
Clear evidence of increasing demands in the processing industry prompted the editors and authors to publish a new book about High Pressure Process Technology: Fundamentals and Applications.This book presents the latest knowledge regarding the high pressure processing aspects combined with that about the modeling, the design and the operation of safe and reliable high pressure plants and equipment. This treatment and selection of the subjects is stimulating and unique. Consisting of nine chapters, each subdivided into several sections, the book addresses the high pressure aspects, providing well selected correlated information connected with a comprehensive overview together with a large number of references. The main body of the first eight chapters refers to subjects like high pressure in general, the thermodynamics and kinetics of the fluids involved, the design of high pressure equipment, the modeling and design of reactors, separation and fractionation units, the safety aspects, the control and economics.In the extended last chapter, examples of promising high pressure applications are explained, such as chemical and enzymatic reactions in supercritical solvents, hydrogenation under supercritical conditions, supercritical water oxidation, polymerization with metallocene catalysts, supercritical extraction, fractionation and precipitation, supercritical pharma processing, ultra-high pressure sterilization and supercritical dry-cleaning.

Book Description
Used Battery Collection and Recycling covers all aspects of spent battery collection and recycling. First of all, the legislative and regulatory updates are addressed and the main institutions and programs worldwide are mentioned. An overview of the existing battery systems, of the chemicals used in them and their hazardous properties is made, followed by a survey of the major industrial recycling processes. The safety and efficiency of such processes are stressed. Particular consideration is given to the released emissions, i.e. to the impact on human health and the environment. Methods for the evaluation of this impact are described. Several chapters deal with specific battery chemistries: lead-acid, nickel-cadmium and nickel-metal hydride, zinc (carbon and alkaline), lithium and lithium-ion. For each type of battery, details are provided on the collection/recycling process from the technical, economic and environmental viewpoint. The chemicals recoverable from each process and remarketable are mentioned. A chapter deals with recovering of the large batteries powering electric vehicles, e.g. lead-acid, nickel-metal hydride and lithium-ion. The final chapter is devoted to the important topic of collecting batteries from used electrical and electronic equipment. The uncontrolled disposal of these devices still containing their batteries contributes to environmental pollution.

Book Description
Brominated flame retardants are one of the last classes of halogenated compounds that are still being produced worldwide and used in large quantities in many applications. They are used in plastics, textiles, electronic circuitry, and other materials to prevent fires. This volume covers the state-of-the-art of the analysis, fate and behaviour of brominated flame retardants. Experts in the field provide an overview of the compounds’ physico-chemical properties and uses, their occurrence in the environment and biota, advanced chemical analytical methods, degradation studies, toxicological effects and human exposure. This book is a valuable and comprehensive source of information for environmental scientists interested in brominated flame retardant issues, and for authorities and producers.

Book Description
Persistent Organic Pollutants (POPs) are toxic, resistant to degradation, bioaccumulative, and display wide spatial distribution. They accumulate in humans and wildlife, and have been linked to cancer, as well as reproductive and immunological disorders. In 2001 a global treaty on POPs was agreed, to minimise and ultimately eliminate the release of POPs into the environment. The Stockholm Convention lists 12 groups of chemicals, and as of late 2008, a further 12 chemicals are under consideration for inclusion. This book addresses all of these chemicals, but focuses particularly on currently listed POPs that are still of major concern (e.g. polychlorinated biphenyls - PCBs), as well as new and emerging POPs that have been the subject of an explosion of scientific interest in the last decade, i.e. brominated flame retardants (BFRs) and perfluorinated chemicals (PFCs). Other chapters address the challenges posed by the presence of POPs in the developing world; how the properties of chiral POPs can provide unique insights into their environmental sources, fate and behaviour; and issues arising from the presence of POPs in urban and indoor environments. Persistent Organic Pollutants provides a much-anticipated reference source for a wide audience including academics, industrial scientists and regulators.
