Book Reviews AROMATIC AMINE OXIDES, by Eiji Ochiai. Elsevier Publishing Com- pany, Ne•vYork, 1967. 456pages, in- dexed. Price $30.00. Aromatic amine oxide chemistry has experienced a dramatic growth in the last twenty to thirty years. This book presents a comprehensive review of a subject in which the cosmetic chemist has become increasingly in- volved. The author states his purpose is to review and communicate efficiently. This goal has been readily achieved by using excellent structuring of sub- ject matter and several organizational techniques. Each chapter is pro- vided with its own list of references (through 196(4) and a footnote on each page denoting the location of these references. Comprehensive Author and Subject Indexes are included. By using a detailed outline form for the Table of Contents, the author per- •nits the reader to peruse the contents rapidly and pick out specific areas of interest. Professor Ochiai has included a gen- erous supply of experimental proce- dures in many chapters thus allowing the reader to utilize the book without an extended literature search. As 211 the author notes, much of the cited experimental work has appeared in the Japanese literature which is not readily accessible or familiar to many industrial chemists. He is to be com- mended for bridging this gap. It would have been helpful, however, had there been provided the Chem- ical Abstract references to these Japanese articles. The book is divided into nine chap- ters. The first two chapters deal with introductory material such as definitions, classification and natural occurrences. The preparation of ar- omatic amine oxides is covered in Chapter 3 and physico-chemical prop- erties are dealt with in Chapter 4. The general chemistry of aromatic amino oxides is covered in Chapters 5 through 8. This includes chemis- try of the N-oxide group, electro- philic substitution reactions, nucleo- philic substitution reactions and the effect of the N-oxide group on various ring substituents. The biological ac- tivity of aromatic amine oxides, a sub- ject of current vital importance to the cosmetic and pharmaceutical indus- tries, is discussed in Chapter 9. The translation from the original Japanese text is excellent, thus allow-

This, coupled with good quality illustrations and appropriate placement and designation of struc- tures, affords a very readable text. The publisher is to be complimented for good book quality which is rela- tively free from typographical errors. Although obviously oriented to- wards the practicing organic and physical-organic chemist, cosmetic chemists of widely differing back- grounds will find this comprehensive review a useful ddition to their li- braries.---PmLL•P E.

The fourth volume in this series contains two sections devoted to specific topics in General Chroma- tography and Gas Chromatography. It is one of a series aiming to promote infornmtion flow from country to country as well as among the spe- cialists in the different branches of chromatography. Each specific topic review is fully supported by refer- ences to original papers and the true international character of this series is reflected in the authors from Ger- many, U.S.S.R., England, U.S.A. and Switzerland. The excellent overall format and style are identical to those of Volumes 1, 2 and 3. The General Chroma- tography section includes discussions of Rf values in thin-layer chroma- tography on Alumina and Silica Steroid Separation and Analysis and some fundamentals of Ion- Exchange-Cellulose design and usage in Biochemistry. The Gas Chroma- tography (G.C.) section includes a lengthy discussion on the influences of various adsorbents in G.C., packed capillary columns, the mass-spec- trometric analysis of G.C. eluents, and the influences of the polarity of stationary liquid phases in G.C. An effective author index at the end of the book cites all references used throughout the text and it also includes an abbreviated subject in- dex, something that should be im- proved upon in the next series. The contributors to this volume, as in the series, have excelled in report- ing major developments and trends in the various specialized fields of chromatography. This is a result of the editors encouragement to the authors of putting their own ideas and opinions in perspective. This book is highly recommended for researchers attempting to keep abreast of progress in the many di- verse areas of chromatography espe- cially those who must rely on more responsible literature surveys. The series as a whole comprises a rich source of information in basic knowl- edge in chromatography.--GEoR• B. ARNOLD, Gillette Research Insti- tute.
