Book Description
Concerns about environmental pollution, global climate change and hazards to human health have increased dramatically. This has led to a call for change in chemical processes including those that are part of chemical analysis. The development of analytical chemistry continues and every new discovery in chemistry, physics, molecular biology, and materials science brings new opportunities and challenges. Yet, contemporary analytical chemistry does not consume resources optimally. Indeed, the usage of toxic chemical compounds is at the highest rate ever. All this makes the emerging field of green chemistry a “hot topic” in industrial, governmental laboratories as well as in academia. This book starts by introducing the twelve principles of green chemistry. It then goes on to discuss how the principles of green chemistry can be used to assess the ‘greenness’ of analytical methodologies. The ‘green profile’ proposed by the ACS Green Chemistry Institute is also presented. A chapter on “Greening” sample preparation describes approaches to minimizing toxic solvent use, using non-toxic alternatives, and saving energy. The chapter on instrumental methods describes existing analytical approaches that are inherently green and making non-green methods greener. The final chapter on signal acquisition describes how quantitative structure-property relationship (QSPR) ideas could reduce experimental work thus making analysis greener. The book concludes with a discussion of how green chemistry is both possible and necessary. Green Analytical Chemistry is aimed at managers of analytical laboratories but will also interest teachers of analytical chemistry and green public policy makers.

Book Description
High-precision cleaning is required across many sectors, including aerospace, defense, medical device manufacturing, pharmaceutical processing, semiconductor/electronics, and more. In this comprehensive reference work, solvent cleaning equipment is thoroughly covered with a focus on the engineering details of its operation and selection. Key data is provided alongside practical guidance, giving scientists and engineers in multiple sectors the information they need not only to choose the correct machine in the first place, but also how to operate it effectively and efficiently. Low emission open-top vapor degreasers, enclosed machines of the vacuum and pressurized type, cosolvent machines, and adsorption of "tailpipe emissions" are covered in detail and fully illustrated in color. This unique book covers material known by designers and manufacturers of solvent cleaning machines, but not collected and organized for the benefit of users. The comprehensive coverage provided by John Durkee makes this book relevant and timely not only for readers who wish to know more about how solvent cleaning equipment works but also those who are under pressure from environmental regulators or corporate management to find effective alternatives and those engaged in non-solvent cleaning operations who are unsatisfied with their cleaning results. - Clear, straightforward explanations of how various types of cleaning solvents should be managed to clean parts - Full-color, hand-drawn illustrations and photographs of the important internal sections of solvent cleaning machines - Design calculations of operating parameters in solvent cleaning machines

Book Description
Everyone is becoming more environmentally conscious and therefore, chemical processes are being developed with their environmental burden in mind. This also means that more traditional chemical methods are being replaced with new innovations and this includes new solvents. Solvents are everywhere, but how necessary are they? They are used in most areas including synthetic chemistry, analytical chemistry, pharmaceutical production and processing, the food and flavour industry and the materials and coatings sectors. However, the principles of green chemistry guide us to use less of them, or to use safer, more environmentally friendly solvents if they are essential. Therefore, we should always ask ourselves, do we really need a solvent? Green chemistry, as a relatively new sub-discipline, is a rapidly growing field of research. Alternative solvents - including supercritical fluids and room temperature ionic liquids - form a significant portion of research in green chemistry. This is in part due to the hazards of many conventional solvents (e.g. toxicity and flammability) and the significant contribution that solvents make to the waste generated in many chemical processes. Solvents are important in analytical chemistry, product purification, extraction and separation technologies, and also in the modification of materials. Therefore, in order to make chemistry more sustainable in these fields, a knowledge of alternative, greener solvents is important. This book, which is part of a green chemistry series, uses examples that tie in with the 12 principles of green chemistry e.g. atom efficient reactions in benign solvents and processing of renewable chemicals/materials in green solvents. Readers get an overview of the many different kinds of solvents, written in such a way to make the book appropriate to newcomers to the field and prepare them for the 'green choices' available. The book also removes some of the mystique associated with 'alternative solvent' choices and includes information on solvents in different fields of chemistry such as analytical and materials chemistry in addition to catalysis and synthesis. The latest research developments, not covered elsewhere, are included such as switchable solvents and biosolvents. Also, some important areas that are often overlooked are described such as naturally sourced solvents (including ethanol and ethyl lactate) and liquid polymers (including poly(ethyleneglycol) and poly(dimethylsiloxane)). As well as these additional alternative solvents being included, the book takes a more general approach to solvents, not just focusing on the use of solvents in synthetic chemistry. Applications of solvents in areas such as analysis are overviewed in addition to the more widely recognised uses of alternative solvents in organic synthesis. Unfortunately, as the book shows, there is no universal green solvent and readers must ascertain their best options based on prior chemistry, cost, environmental benefits and other factors. It is important to try and minimize the number of solvent changes in a chemical process and therefore, the importance of solvents in product purification, extraction and separation technologies are highlighted. The book is aimed at newcomers to the field whether research students beginning investigations towards their thesis or industrial researchers curious to find out if an alternative solvent would be suitable in their work.
