Abstract
ESSENTIALLY a summary of a good deal of information hitherto available only in a dispersed form in recent chemical literature, this book provides a comprehensive list of organic reagents which may be used in identification work for the preparation of crystalline derivatives of various organic types. To illustrate its scope, we may note that under the alcohol type are given eight 'selected reagents' and eleven 'other reagents', the former being as a rule more satisfactory and easier of access than the latter, for details of which the reader is referred to the original literature. Choosing 3: 5-dinitrobenzoyl chloride as a typical 'selected reagent', we find a description including its structural formula, molecular weight and significant properties, with experimental details for its use in preparing derivatives of alcohols and phenols, together with notes on other applications, a bibliography, and references to tables of melting-points given at the end of the volume. To name a less familiar example, xanthydrol is described, on a similar plan, as a reagent for amides, urethanes, sulphonamides and substituted barbituric acids. There is a good index.
