spectrometric work.
The author’s great experience in mass spectrometric structural
analysis is evident from the many valuable and practical
directions. The book provides an excellent foundation for
chemists who have to deal with mass spectrometry of organic

Grundlagen der Synthese von Zwischenprodukten und Farbstoffen (Principles of the Synthesis of Intermediates and
Dyestuffs). By N . N . Woroshzow, Translated into German
by E. Baumann and F. Baht-. Akademie-Verlag, Berlin 1966,
1059 pp., 26 illustrations and 12 charts, D M 135.--.
After an interval of several decades a major work has
appeared in which the principles of the synthetic methods
of interest in dyestuff chemistry are discussed in detail. The
present book contains a wealth of material collected from the
literature and critically surveyed. An introductory chapter,
treating in particular the principles of aromatic electrophilic
and nucleophilic substitution, is foIIowed by 14 chapters
concerned with sulfonation, nitrosation, introduction of
halogen, introduction of amino groups, replacement of the
sulfo group by a hydroxyl group, replacement of halogen by
other substituents, interconversion of amino and hydroxy
compounds, diazotization, acylation, oxidation, and sulfuration, reduction of compounds containing nitrogen-free
functional groups, condensations, and rearrangements.
The individual chapters treat the synthetic principles in
general first, then the mechanistic principles, and finally the
preparative and sometimes the technical operations, as well
as special cases. Every chapter is characterized by an extraordinarily large number of references to the old and new
literature; the many references to Russian papers are sure
to be of particular importance to readers in the Western
hemisphere. One can point, for instance, to the discussion of
the kinetics of alkali melts (p. 351) where it is shown that the
experimental proof, usually attributed to J. F. Bunnett, for
the two-stage mechanism of nucleophilic aromatic substitution
by means of Bodenstein’s equation for the stationary state,
was given as early as 1938 by Woroshzow jun. for alkali melts
of aromatic sulfonic acids.
On the other hand, a remarkable feature of this book is that
sections presented in a very modern way are often placed
next to problems that are discussed in the manner of the
1920’s. In spite of this limitation, Woroshzow’s book is a
mine of knowledge, not only for the dyestuff chemist, but
also for all chemists who are interested in the principles of
aromatic chemistry. It shows agaiii how many interesting
basic problems advanced by the technical development of
dyes during the past hundred years still await detailed

Zuckerchemie. Eine Einfiihrung (Sugar Chemistry. An Introduction). By G . Henseke. Akademie-Verlag, Berlin 1966.
1st Edit., 267 pp., 3 tables, 3 charts, D M 25.-.
This little book follows a mainly conventional pattern. Thc
author has succeeded in collecting a very large amount of
the wide area of carbohydrate chemistry in a small space;
the book consequently bears some resemblance to a dictionary. Corresponding to their importance, the significant
classes of compound and the fundamental reactions are
discussed, their arrangement being easy to follow. In this
respect the book fulfils its purpose and provides a rapid
survey for all who are interested and particularly for readers
who are not chemists. The numerous formulas are clear
and have been prepared with great care; however, most of
them are drawn with the sugar chain vertical, whereas in
recent years presentation by means of ring formulas and,
whenever possible, by stereochemical formulas has been
preferred because these lead to a better understanding of the
Angew. Chem. internat. Edit. / Vol. 7 (1968) J No. 3
actual molecular shapes and the course of reactions. It is only
in the latter way that the reader can readily appreciate how
considerations of mechanisms developed in the past decade
and modern methods of measurement apply also to carbohydrate chemistry. The relation of reaction mechanism to
stereochemistry, questions of conformational analysis, and
the importance of N M R spectroscopy for determination of
structure could well have been more strongly emphasized.

Kunststofftechnisches Worterbuch (Plastics dictionary), Vol.
111, French-German. By A . M . Wittfoht. Carl Hanser Verlag, Miinchen 1966. 1st Edit., xvi, 768 pp., plastic cover,
D M 124.-.
The previously published Volume 4 (German-French) has
been warmly recommended because of the very good compilation and excellent explanation of individual words, often
supported by most useful drawings and diagrams.
The same can be said about the present volume. As such, the
dictionary is exemplary in arrangement and typography, and
hence very lucid as well as convenient to use. The fields of
application of plastics dealt with in Volume 4 , e.g. adhesives,
reinforced plastics and foams, have been expanded to include the latest developments. Novel chemical processing and
processing machinery, e.g. winding techniques and heat
insulation by ablation, have been added. The inclusion of
units and standards employed in plastics testing is welcome,
A further feature is the inclusion of size-reduction machinery,
winding techniques, glass fibers, coating, dryers, welding and
a section on “plastic pipes” in the illustrated section previously comprising shaping, presses, molds, processing and
A very high standard has been achieved through the collaboration of numerous German and French specialists, particularly Max Windsor, whose name appears as co-editor.
The book has become the standard work in the plastics field
for technologists, businessmen, and translators alike, and can
be warmly recommended to all interested in this field.

Zur Viskosimetrie (Viscometry). By L. Ubbelohde. Completely
revised by G. H. Gottner and W . Weber. S . Hirzel Verlag,
Stuttgart 1965. 7th Edit., xii, 75 pp., 15 illustrations and
1 9 tables, DM 18.60.
The seventh edition of this standard work, which has been
thoroughly revised, differs from the previous editions in
introduction of the standard value 1.002 c P for the viscosity of water a t 20 “C.
The book is divided into three parts: a general part, a
theoretical part, and tables for conversions and calculations.
A pleasing feature is the concise and clear exposition, which
strives towards a general presentation of the problems of
viscometry and yet remains close to everyday practice.
The book has won for itself a wide readership among
research and industrial workers, although in this edition
specialization on the requirements of the petroleum industry
