NEW BOOKS Textbook of Practical Organic Chemis try, Including Qualitative Organic Analysis. Arthur I. Vogel. Third edition, xxvii + 1188 pages. Long mans, Green and Co., Inc., 55 Fifth Ave., New York 3, Ν. Υ., 1956. $12. The third edition of Vogel's book has been completely revised and consider ably enlarged in the light of the numer ous developments that have taken place since the book was first written in 1945-46. The net result has been an increase in the length of the volume by some 150 pages. The book, which is now a complete up-to-date textbook of practical organic chemistry (excluding quantitative analysis), should meet the requirements of students of organic chemistry at all levels. It should also continue to be of value as a one-volume reference work in the laboratory, since it comprises at least three books under one cover—namely, experimental technique, preparations, and quantitative organic analysis. The preparation of about 900 com pounds is described, as well as most of the modern techniques. Also included are numerous new preparations thor oughly tested in the laboratory. Some of these more important new prepara
tions are contained in chapters on Ali phatic Compounds; Aromatic Com pounds; Heterocyclic and Alicyclic Compounds; Miscellaneous Reactions; Organic Reagents in Inorganic and Organic Chemistry; Dyestuffs, Indi cators, and Related Compounds; and Some Physiologically Active Com pounds. A new feature is the account of the electronic mechanisms (in outline form) of the numerous reactions described in the text. Of particular interest to the analytical chemist are the chapters on qualitative organic analysis and semimicro technique. In the latter, a few examples of small scale preparations are included, together with a suggested list of experiments for an elementary course. The size of the volume makes litera ture references impossible and a selected bibliography is included to compensate in part for the omission. Of consider able help is the addition of section numbers, which are now included in the headings of the pages. This edition, like the others, should be a valuable reference to the research worker as well as to the student.
N e w Methods in Analytical
Chemistry.
Ronald Belcher and Cecil L. Wilson, xii + 287 pages. Chapman & Hall, Ltd., 37 Essex St.. London 1955. 30s. Reviewed by H. FREISER, University
of Pittsburgh. Belcher and Wilson have compiled "some of the more promising of the newer analytical methods based on clas sical techniques" in this brief though useful volume. Gravimetric and titrimetric methods for determination of inorganic constituents form the major portion of the book. The use of organic reagents is prominently featured. The authors have performed a distinct serv ice in drawing attention to methods which deserve more notice than they seem to have received. For example, 8hydroxyquinaldine was introduced by Merritt and Walker in 1944 for the de termination of metals in the presence of aluminum but, surprisingly, has not been widely applied for this purpose. The description of the 8-hydroxyquinaldine methods in this volume may well serve to "resurrect" this useful reagent. Of course, with this and other organic reagents, much depends upon the com mercial availability of the compound. In addition to general descriptive ma terial concerning each of the methods, a detailed procedure is included, making this text a handy work and reference book that all analysts will wish to have close by on their book shelves.
