The aim of this book is to present the current state of the art of extracting natural products with near-critical solvents and to view the possibilities of further extensions of the technique. Relevant background theory is given but does not dominate the book. Carbon dioxide is the near-critical solvent used in most recent applications and inevitably receives prominence. In addition to general descriptions and reviews, the book contains three chapters by indus trial practitioners who describe in detail the operation of their processes and discuss the market for their products. Sections on the design of the pressure vessels and pumps required in these processes and on the acquisition of the data required for design are included. The costing of the processes is also discussed. There is good scope for combining a near-critical extraction step with other process steps in which the properties of near-critical solvents are utilised, for example as a reaction or crystallisation medium and a chapter is devoted to these important aspects. It is hoped that the work will be found to contain a great deal of specific information of use to those already familiar with this field. However the style of presentation and content is such that it will also be useful as an introduction. In particular it will be helpful to those wondering if this form of separation method has anything to offer for them, whether they are engineers, chemists or managers in industry, or in academic or research institutions.

Natural products are sought after by the food, pharmaceutical and cosmetics industries, and research continues into their potential for new applications. Extraction of natural products in an economic and environmentally-friendly way is of high importance to all industries involved. This book presents a holistic and in-depth view of the techniques available for extracting natural products, with modern and more environmentally-benign methods, such as ultrasound and supercritical fluids discussed alongside conventional methods. Examples and case studies are presented, along with the decision-making process needed to determine the most appropriate method. Where appropriate, scale-up and process integration is discussed. Relevant to researchers in academia and industry, and students aiming for either career path, Natural Product Extraction presents a handy digest of the current trends and latest developments in the field with concepts of Green Chemistry in mind.

The term “natural products” spans an extremely large and diverse range of chemical compounds derived and isolated from biological sources. Our interest in natural products can be traced back thousands of years for their usefulness to humankind, and this continues to the present day. Compounds and extracts derived from the biosphere have found uses in medicine, agriculture, cosmetics, and food in ancient and modern societies around the world. Therefore, the ability to access natural products, understand their usefulness, and derive applications has been a major driving force in the field of natural product research. The first edition of Natural Products Isolation provided readers for the first time with some practical guidance in the process of extraction and isolation of natural products and was the result of Richard Cannell’s unique vision and tireless efforts. Unfortunately, Richard Cannell died in 1999 soon after completing the first edition. We are indebted to him and hope this new edition pays adequate tribute to his excellent work. The first edition laid down the “ground rules” and established the techniques available at the time. Since its publication in 1998, there have been significant developments in some areas in natural product isolation. To capture these developments, publication of a second edition is long overdue, and we believe it brings the work up to date while still covering many basic techniques known to save time and effort, and capable of results equivalent to those from more recent and expensive techniques.

This 4th edition of Handbook of Solvents, Volume 2, contains the most comprehensive information ever published on solvents as well as an extensive analysis of the principles of solvent selection and use. The book begins with a discussion of solvents used in over 30 industries which are the main consumers of solvents. The analysis is conducted based on the available data and contains information on the types (and frequently amounts) of solvents used and potential problems and solutions. Picking up where Handbook of Solvents, Volume 1 leaves off, Handbook of Solvents Volume 2 provides information on the methods of analysis of solvents and materials containing solvents, with 2 sections containing standard and special methods of solvent analysis, followed by a discussion of residual solvents left in the final products. The environmental impact of solvents, such as their fate and movement in the water, soil, and air, fate-based management of solvent-containing wastes, and ecotoxicological effects are discussed as are solvents’ impact on tropospheric air pollution. The next 2 chapters are devoted to the toxicology of solvents and regulations aiming to keep solvent toxicity under control. The analysis of the concentration of solvents in more than 15 industries, specific issues related to the paint industry, and characteristics of the environment in automotive collision repair shops are followed by a thorough discussion of regulations in the USA and Europe. Following chapters show examples of solvent substitution by safer materials, with an emphasis on supercritical solvents, ionic liquids, deep eutectic solvents, and agriculture-based products, such as ethyl lactate. Discussion of solvent recycling, removal, and degradation includes absorptive solvent recovery, comparison of results of recovery and incineration, and application of solar photocatalytic oxidation. The book concludes with an evaluation of methods of natural attenuation of various solvents in soils and modern methods of cleaning contaminated soils. Assists in solvent selection by providing key information and insight on environmental and safety issues Provides essential best practice guidance for human health consideration Discusses the latest advances and trends in solvent technology, including modern methods of cleaning contaminated soils, selection of gloves, suits, and respirators
