The Analytical Chemistry of Synthetic Dyes. Edited by K .
Pknkataraman. John Wiley & Sons, New York-London
1977. xxiv, 591 pp., numerous figs. and tables, bound,
E 31.90.
This book, a collaborative effort of 23 authors, presents in 20
chapters the method used in dyestuff analysis. Thephysicochemical methods customarily used in the analysis of dyestuffs are
treated in the first ten chapters (thin-layer chromatography,
paper chromatography, paper electrophoresis, high-pressure
liquid chromatography, gas chromatography, colorimetry in
dyestuff solutions, IR, NMR, and mass spectrometry, as well
as X-ray diffraction), though in these descriptions fundamental
theoretical and practical knowledge is assumed. The standpoint of methodical application to dyestuff analysis is given
prominence, and the articles therefore correspond to the
readers’ expectations. Somewhat too little information is given
in the chapter on mass spectrometry: having 13 pages, it
is about the same length as the chapter on gas chromatography
(1 1 pages), which is relatively unimportant for dyestuff analysis.
The chapter on methods of chemical degradation is too
short, and in addition the references given are sometimes
difficultly accessible. Some procedures, e. g. pyrolysis and dry
distillation with alkali metal hydroxides, are described too
briefly, although in difficult cases these can provide decisive
evidence for the structure of a dye.
The identification of dyes and pigments on their substrates
is treated well and extensively. A chapter on quantitative
dyestuff analysis deals mainly with dyes fixed on textile fibers.
Special themes, such as analysis of hair dyes and of dyes
for foods, drugs, and cosmetics, are also treated. The conclusion
of the book is an opportune contribution to ecological and
toxicological problems.
By and large, Venkataraman’s new book provides a satisfactory presentation of the themes discussed. The 1200 references
help in delving deeper into specific questions. The book closes
a gap in the chemical literature; it will be welcomed not
only by the dyestuff analyst but will also prove of value
to the dyestuff chemist engaged in preparative work.

Energetic Materials. Vol. 1. Physics and Chemistry of the
Inorganic Azides. Edited by H . D. Fair and R. F. Walker.
Plenum Press, New York 1977. 1st edit., xv, 503 pp.,
numerous figs. and tables, bound, $ 59.40.
Although azides have been known since 1890 and a large
number of ionic and covalent inorganic azides have been
prepared, most of the detailed work on their physical properties
in particular was done only in the last two decades.
The present book opens with a brief introduction followed
by nine main chapters to which several authors contributed.
These deal mainly with the physical properties of azides and
with their decomposition reactions induced by physical means,
the literature up to about 1975 being considered. The first
chapter gives a review of the inorganic and organometallic
azides and of the general and special methods used in their
preparation. Next information is provided about crystal
growth and crystal structures, very many data being presented
in tables and important structures being illustrated. There
is an excellent and very extensive review of molecular and
lattice vibrations, of optical and electrical properties, and
of electron structure calculations. The last four chapters deal
very carefully with the stability of azides and with their slow
or rapid decomposition induced by heat, friction, impact,

electricity, or irradiation. The progressive development of
explosions is demonstrated by many photographs.
For all who work with azides this book can be strongly
recommended as a mine of information on the literature and
data available on the physicochemical behavior of this class
of compounds. The data are presented critically and from
diverse points of view, and open questions are faced honestly
and not simply buried.

Azides. Edited by H . D. Fair and R . F. Walker, Plenum
Press, New York 1977. 1st edit., xiv, 296 pp., numerous
figs. and tables, bound, $ 47.40.
The information collected in the last twenty years on the
technology of azides, in particular the technology of lead
and silver azides, is reported in this book in a set of seven
The first chapter contains a really detailed account of the
preparation, stabilization, and processing of lead and silver
azides. The plant used for their manufacture and the products
are illustrated by photographs. Many physical properties of
the products stabilized in a variety of ways are tabulated.
A further chapter deals with the analysis of, in particular,
industrial products for their azide content and traces of metals.
In line with the character of these compounds, the following
four chapters are devoted in particular detail to the handling,
storage, and destruction of these materials, to sensitivity tests,
and to their reactions and to impact, friction, heat, radiation,
and electricity. The physiological action of azides is also mentioned. The last chapter concerns the use of azides as detonators and as explosives.
The book as a whole contains an abundance of industrially
important data, plant, and technical drawings. If we except
the analytical chapter, the book will thus be of the greatest
value to readers with industrial interests. On the other hand,
it would be advantageous to all dealing with azides to learn
the many tests that permit statements to be made about
the behavior of this class of compounds toward external

Grundlagen der enzymatischen Analyse (Principles of Enzymatic Analysis). Edited by H . U . Bergmeyer in collaboration
with K . Gawehn. Verlag Chemie GmbH, Weinheim-New
York 1977. 1st edit., xii, 267 pp., 99 figs., 30 tables, bound,
D M 44.-.
The many new procedures of enzymatic analysis and the
increasing mechanization of modern clinical and biochemical
laboratories led to the decision to publish separately the
chapter on “Principles of Enzymatic Analysis” from Bergmeyer’s valued major workC*].
The book is divided into the following main sections: 1.
Introduction, 2. Theoretical Principles, 3. Handling of Biochemical Reagents and Sample Material, 4. Techniques of Measurement and Apparatus, and 5. Obtaining and Assessing
Results of Measurements.
Naturally, for methods for the determination of individual
enzymes, the reader must still turn to the larger work. The
“Principles” rather explain the quantitative procedures customary today and the experimental details of biochemical
analysis. The conclusion is a review of the numbering and
