xix This page intentionally left blank Preface
Fatty Acids, esterified to glycerol, are the main constituents of oils and fats. The oils and fats are the renewable resources for the chemical industry. The industrial exploitation of oils and fats, both for food and oleochemicals, is based on chemical modification of both the carboxyl group and unsaturation present in fatty acids. The oleochemicals could add value to existing crops and provide market for new crops, and research leads to novel fatty acids derivatives. The oleochemical production involves reaction at the carboxyl group, with the chain length, and at unsaturation of the fatty acid chain to give products of the desired structure and properties. Introducing functional- ity to the alkyl chain through known chemical reactions leads to novel com- pounds with commercial potential. The carboxyl groups and the unsaturated centers generally react independently, but when they are in proximity, they might react through neighboring group participation. In enzymatic reactions, the reactivity of the carboxyl group can be influenced by the presence of double bond in close proximity. The coverage in this book is selective, focusing on industrially important fatty acids, their chemistry and synthesis. Historical perspective of important developments in the chemistry of fatty acids in the last 100 years is pre- sented. The main emphasis of this book is on enzymatic and chemical syn- thesis of fatty acids and derivatives; naturally occurring fatty acids, their purification and preparation for various applications; presence of unusual cyclic fatty acids like epoxy fatty acids and carbocyclic fatty acids in seed oils and their chemical and biological properties; natural and synthetic acety- lenic epoxide and their industrial importance; microbial production of fatty acids; biosynthesis of vegetable oils and process improvement, new plant sources to meet future world needs of fatty acids; industrial importance of castor oil and derivatives; crystallization of fatty acids in edible oils and their structure; free fatty acid oils for biodiesel production; advancement in syn- thesis of sugar fatty acid esters and their applications; fatty acids based sur- factants; fatty acids in Cosmetic Technology; chemistry of long-chain α,β-unsaturated fatty acid and derivatives; synthesis of different types of estolides as next generation of high-performance synthetic lubricant; synthe- sis of dietary cis- and trans-octadecenoic (18:1) fatty acids present in par- tially hydrogenated vegetable oils; chromatographic and spectroscopic
xxi xxii Preface analyses of dietary fatty acids; mass spectrometry based methods for the analyses of fatty acids and derivatives. This book serves as reference manual to new generation of lipid scientists and researchers, useful for oleochemical industries, a valuable teaching resources for undergraduate and graduate students interested in the field of chemistry of oils, fats, and fatty acids, food chemistry, cosmetics and per- sonal care products, and pharmaceuticals. This book also serves as a valuable reference and resource for those interested moving in the field of chemistry and technology of fatty acids. The goal in writing this book is to gather writ- ing from many of the leaders in the field who had published one or several articles in various aspects of fatty acids chemistry. The authors have publica- tions in the field of oils, fats, and fatty acids and are imminently qualified to summarize their own work and related work in their field of expertise. It is hoped that the readers will find it valuable to read and this will help them to understand the field of oils, fats, and fatty acids, and their utilization in oleo- chemical industries. I would like to thank all contributors for their magnificent work in the collection of research publications and their devotion to presenting accurate and detailed scientific information. The assistance from Academic Press (Elsevier) and AOCS Press is greatly appreciated with special thanks to Billie Jean Fernandez and Janet Brown. Moghis U. Ahmad Chapter 1
