The purpose of this book is to help chemists, biochemists and other scientists to purify the chemical reagents which they use in their work. Despite the fact that commercially available chemicals are often of a very high quality and quite satisfactory for some applications within science and technology, it is becoming almost as important to know what impurities are present and to make allowance for them as to remove them completely. This book aims to show how. The main chapters describe processes, taken from the literature, for purifying over 4000 organic and 750 inorganic or organometallic commercially available chemicals. Further chapters describe the methods and techniques used for purification in laboratories and prescribed in the text. Methods for purifying classes of chemicals where specific compounds are not treated individually in the text are dealt with in a separate chapter. This expanded and revised fourth edition includes new material dealing with modern reagents for natural products chemistry, protein biochemistry and molecular biology. It also includes many individual compounds not previously covered, and more information is given on most entries, including melting and boiling points, molecular weights, refractive indexes, densities and CAS registry numbers, as well as likely contaminants and storage conditions in appropriate cases.

"This monograph remains the bible for practising chemists... (It) will be the most commonly used reference book in any chemical or biochemical laboratory."--MDPIFrom the Back Cover:
Purification of Laboratory Chemicals
Wilfred L.F. Armarego, John Curtin School of Medical Research, Australian National University, Canberra
Christina L.L. Chai, Department of Chemistry, Australian National University, Canberra
·The only complete source that covers the purification of laboratory chemicals that are commercially available in such an easy-to-use format
·Provides purification procedures for commercially available chemicals and biochemicals
·Includes an extremely useful compilation of ionisation constants
Now in its fifth edition, Purification of Laboratory Chemicals continues to provide laboratory scientists with a manual for purifying and increasing the purity of modern commercially available chemical substances.
The authors have written and revised six chapters that describe the aspects of purification and properties of chemical substances. In addition to detailing physical methods and procedures such as crystallization, distillation, chromatography, etc., the authors also address chemical methods and procedures used in purification including conversion to specific derivatives or complexes and regeneration of the original material in a much-purified form.
The book also outlines recent developments in synthesis (e.g. combinatorial chemistry, solid support chemistry, fluorous chemistry) and the corresponding purification procedures that will provide many of the commercially supplied chemical substances in years to come. Additionally, interesting perspective about the future of purification is provided by the authors, based on their years of experience.
The bulk of the book contains purification procedures (taken from the literature) of individual entries for commercially available organic compounds, inorganic and metal-organic compounds, and biochemical and related compounds respectively. The entries are accessible in alphabetical order, and in most cases synonymous names and/or abbreviations are included as well as the CAS (Chemical Abstracts Service) Registry Numbers. The physical properties have been entered, such as the molecular weight, melting and boiling points, and specific rotations if substances are optically active. Rapid purification procedures for common solvents have also been included after the respective extensive procedures.
New to this edition, the ionisation constants in the form of pK have been entered for ionisable compounds. These are followed by procedures, used to purify the substances, in most cases to analytical purity. An index of CAS Registry Numbers with the respective page numbers of the entries has been added as well, making it easy to locate any substance irrespective of which chapter it is in, and also rapidly telling the reader whether there is a purification procedure for that substance in this book.
