Allen's Commercial Organic Analysis

Abstract

A PERIOD of fourteen years has elapsed since the publication of the equivalent volume in the last edition of Allen's “Commercial Organic Analysis.” The reputation of this standard text-book is definitely upheld in the new volume. A comparison of the old and new shows that a thorough revision of data from the analytical investigation of fixed oils, fats, and waxes has been made, resulting in a considerable increase in the size of the book. A part of the increase is due to the fact that, while giving the latest and best methods, the older methods have in many cases been also intentionally retained. The section on the special characters and modes of examination of fats, oils, and waxes has been doubled in size and now covers nearly half the book, while some of the smaller sections show a fourfold expansion. Many subjects practically unknown in commercial analysis when the previous issue appeared (e.g. fermentation glycerin, vitamins, montan wax, etc.) have now their place in the new edition. In the refined glycerin section, a reference is to the excellent “Ardeer Analytical Methods” book, but, so far as the reviewer is aware, this analytical process book is only available for private use in the Nobel Laboratories.
