Enantiomer Separation: Fundamentals and Practical Methods

Enantiomer Separation is written by several experts working in modern enantiomer separation chemistry who understand the needs of the many scientific and engineering chemists who need a cost-efficient supply of optically active materials of high quality. This book contains the following modern practical methods of enantiomer separation: Inclusion complexation of a racemic compound with a chiral host compound, which gives chiral host-chiral guest inclusion compounds, from which the chiral guest can be obtained. When this separation is combined with distillation technique, for example, enantiomer separation can be accomplished by fractional distillation in the presence of a chiral host compound. This is a modern and "green" procedure of enantiomer separation. These separation methods are described in several chapters of the book. Biological separation methods and "green" methods are covered in two chapters. Enantiomer separation by chromatography on a column containing chiral solid phase is one of the most up-to-date and well known "green" methods of enantiomer separation. Two experts in chromatography have contributed to provide two very important chapters on this method of separation. Practical methods of enantiomer separation are important both in the research laboratory and in industry, especially in the pharmaceutical, fine chemical and electronic industries. Chemists and engineers, as well as students who are working in the field of chiral compounds in universities, institute and industry, will find this book an invaluable resource.
