the Flyleaf Technique of Organic Chemistry. Vol. II.

Catalytic, Photochemical, and Elec­trolytic Reactions. ARNOLD WEISSBER-GER, editor, xi -f- 219 pages. Inter-science Publishers, Inc., 215 Fourth Ave., New York, Ν . Υ., 1948. $5.00.

1 HIS book, which is Vol. II of the series "Technique of Organic Chemistry," contains three reviews: ''Catalytic Reac­tions" by V. I. Komarcwsky and C. H. Riesz; "Photochemical Reactions" by W. A. Noyes, Jr., and V . Boekelheide; and "Electrolytic Reactions' ' by Sherlock Swann, Jr. Vol. I, "Physical Methods of Organic Chemistry/ ' appeared in two parts (CHEM. E N G . N E W S 24, 100 [1946] and 24, 2108 [1946]).

The title of the article on catalytic reac­tions is somewhat of a misnomer. It might better have been "Catalysts and Catalytic Apparatus." About 12 pages are devoted to a good summary of the gen­eral methods of preparing catalysts. Most of the remainder is an excellent descriptive and profusely illustrated review of the physical apparatus and equipment used in carrying out catalytic reactions at at­mospheric, subatmospheric, and superat-mospheric pressures, both in batch (the familiar and very useful Parr hydrogéna­tion apparatus is not mentioned) and con­tinuous flow systems. T o this reviewer's knowledge, such information has not been published previously in one place and will be valuable t o chemists contemplating the use of catalytic procedures. On the other hand, since space was apparently limited, it would probably have been preferable to have omitted many of the i l­lustrations (particularly those taken from readily available primary references) and to have used the space (at least 15 pages would have been made available) for a n outline of the types of catalytic reactions and the techniques used in carrying them out in the laboratory. For example, fig­ures showing the cross sections of high-pressure valves are not as helpful to the practicing organic chemist as would be a discussion of the technique of carrying out reactions in t h e presence of liquid anhy­drous hydrogen fluoride. More examples of the applications of the various types of equipment as well as a comparative evalua­tion would have been desirable.

The chapter on photochemical reactions is a very well-written and balanced dis­cussion of the types of photochemical reac­tions and of the apparatus and techniques. The value of this chapter lies not only i n that i t shows what can be done with photo­

chemical reactions, but in that it stresses limitations of the method.

The discussion of electrolytic reactions follows an outline similar to that used in the article on photochemical reactions. A perhaps unique feature of this article is that constant reference is made to three review articles on electro-organic chemical preparations which were published by Prof. Swann in the Transactions of the Electrochemical Society. These reprints, available (at a nominal price) from the University of Illinois, should be obtained and used in conjunction with the article in order to have a very comprehensive review of electrolytic reactions. Furthermore, some statements in the article are incom­plete without the aid of these reprints.

Except for the omissions mentioned above, the book serves as very satisfac­tory review of the techniques of catalytic, photochemical, and electrolytic reactions. I t will be consulted frequently by organic chemists, particularly those interested in synthesis. Lou i s SCHMERLING

164 pages. Macmillan C o . , 60 Fifth Ave., N e w York 11, Ν. Υ., 1948. $1.75.

U N F O R T U N A T E L Y , comparative bio­chemistry, unlike comparative anatomy or physiology, has been a subject much neglected by both research workers and teachers. It is therefore gratifying that Dr. Baldwin's book has found enough readers t o warrant a third, enlarged and revised, edition.

The book itself gives an interesting sur­vey of the scope of comparative biochem­istry, and it should prove v e r y helpful t o students and others interested, but not specializing, in this field. I t i s well writ­ten, and the general bibliography which has been provided will assist traose readers who become sufficiently interested i n the subject t o follow it up. The various chap­ters give concise summaries of the bio­chemical relations which have been most studied, such as blood electrolytes, metabo­lism of nitrogenous compounds, respira­tion, and nutrition. It is to b e regretted that the chapter on animal pigmentation had to b e confined to an enumeration of more or less unrelated facts.

The development of biochemical reac­tions in the course of evolution neces­sarily had a decisive influence o n the reactions of biochemical systems as w e orb-serve them today. I t is to b e hoped that

Dr. Baldwin's book will continue to stimulate intensified study of comparative biochemistry. With the aid of the tools of modern science this branch of biology will certainly further our understanding of all living matter. H. S. ANKER

Elements of Coal Chemistry. D. J. W. KREULEN. 204 pages. Nijgh & Van Ditmar N. V., Rotterdam-'s-Graven-hage, 1948. Fl. 18.25.

I HE publication of this monograph in English makes available in convenient form a résumé of many investigations pre­viously described mostly in the Dutch journals by the author. D. J. W. Kreulen, lecturer on fuel chemistry and technologv at the University of Utrecht, recently was honored on the occasion of the twenty-fifth anniversary of his establishment of the Laboratorium Voor Brandstof-en Olieonderzoek in Rotterdam.

Treatment of the subjects covered in the 17 chapters is not comprehensive and in certain cases not critical in the sense that other significant work on the same subject is not considered. Subjects in which the author has not been actively en­gaged are treated quite inadequately in the chapters assigned to them—e.g., the hy­drogénation of coal. However, those in­

terested in the chemistry of coal will be re­paid by reading t h e descriptions of Kreulen's own work, particularly on humic acids, the mechanism of coal oxidation, the spontaneous combustion of coal, coal ex­traction, and the properties and origin of coal bitumens. It would be an interesting exercise to reinterpret much of the data presented in terms of coal being a natural, thermally unstable polymer instead of the micellar structure of a disperse and con­tinuous colloidal system postulated by Kreulen.

The book is well printed. It lacks an index. The bibliographies at the end of each chapter arc highly selective. The English is generally good, th.ough, as may be expected in a foreign language, choice of words, spelling, and abbreviations are sometimes unusual. H. 1-1. LOWRY

The book is recommended as the only available textbook dealing with the present trend toward orderly processes of chemical marketing. It is issued at an advantageous time when chemical companies are getting away from early marketing methods based on whim or guess and substituting well organized market studies by highly skilled personnel. The efforts of specific com­panies to systematize the introduction of new products is discussed and is especially useful· The bibliography of over 100 references will be helpful to those studying the subject. The authors in attempting to cover a field so broad have been forced to a coverage which in certain passages is en­tirely inadequate; in many cases the coverage is nothing more than an outline of the matter involved. The authors have relied on the authority of many references available in the literature of chemical marketing without a serious attempt at critical analysis or without an adequate description of the theories and practices involved. For this reason the subject matter is presented in a jumpy manner which at times is very difficult to follow. This approach has also led to some repeti­tion and even to some contradiction. The authors state in their preface that the present book is a preliminary version of one which will treat the broader aspects of chemical marketing and market research. More careful proofreading would eliminate many simple but confusing errors in the present edition. LAWRENCE FLETT

Industrial Hygiene and Toxicology FRANK A. PATTY, editor, xxvii -f- 531 pages. Interscience Publishers, Inc., 215 Fourth Ave., New York 3, Ν . Υ., 1948. $10.

L HE editor of "Industrial Hygiene and Toxicology" and his collaborators are to be congratulated on making available in concrete form the material which is com­prised under the general heading of indus­trial hygiene. The health of our industrial workers is a matter which has received a tremendous impetus during the past 25 years, and this increasing social conscious­ness is reflected in the extent t o which in­dustrial hygiene has grown. The scope of present volume is indicated by the follow­ing representative topics: industrial hy­giene—retrospect and prospect, records and reports, surveys and personnel, per­sonal and environmental factors in fatigue and competence, physiological effects of abnormal atmospheric pressure, action of toxic materials, sampling and analysis of atmospheric contaminants, radiant energy, ventilation, occupational dermatoses, fire and explosion hazards of gases, respiratory protective devices, and the role of dust in occupational disease.

The presentation of this material in a single volume will be of special value to the industrial hygienist who does not have an

Save needless wasie In one form or another acids, alkalis, salts, gases and atmospheric conditions cause corrosion damage. In every industry losses are prevalent — losses in time, materials and equipment, much of which could have been avoided. Minimize your risk — do these two things now —

1 — Check up on your costs;

2 — Provide adequate protection for danger points.

Experienced and competent Amercoat engineers are available to help you on both. They'll check up on your costs, which may be greater than you know because the effects of corrosion are often hidden. They'll report on conditions as they find them. They'll recommend steps to take if greater protection can be provided and money saved. Inquiries from interested executives will receive prompt attention. There's no
