tially complete. O n the whole this volume is a good start
to the new series. It can be strongly recommended to
all those who wish to gain a detailed understanding of
the hydrido complexes of the transition metals.

Chemical Analysis of Additives in Plastics. By T. R. Crompton. Pergamon Press, Oxford-New York 1971. 1st ed.,
xi, 162 pp., numerous figures, bound L 7.-.
Few plastics are used at present without additives such
as plasticizers or stabilizers. The identification and determination of such substances is frequently necessary for
a wide variety of reasons, but is very difficult and expensive
in some cases. The very extensive literature in this field
is widely scattered and often applicable only to very special
cases, so that there is a clear need for a good survey
that would be of use to the practical worker.
The present book deals with the analysis of additives,
not according to their chemical structure or fields of use,
but mainly from the standpoint of methods. The qualitative
analysis of known additives (phenolic and amine antioxidants, plasticizers, UV absorbers, peroxides, and various
monomers) by spectroscopic methods and by thin layer
and column chromatography is discussed in the first two
chapters. The chromatographic methods, partly in combination with spectroscopy, for the identification and quantitative determination of unknown additives are then considered; the final chapter contains examples of the applications of gas chromatography, and the determination of
monomers and volatile impurities is also discussed.
In comparison with the existing literatuke, the total of
330 references is rather small, but they cover the principal
topics, though sometimes in a very arbitrary selection.
The experimental data in the book are too concise in
most cases, so that they cannot be followed directly in
practice. One major disadvantage is that practical procedures and descriptive passages follow one another with
little rhyme or reason, so that it is often very difficult
to obtain a general picture. Little help is offered in this
respect by the very brief list of contents and the index,
which includes only about 170 keywords.
Apart from these limitations, the book will undoubtedly
be a useful aid to the experienced plastics analyst, and
should have a place in every reference library in this field.
In a second edition, we would like to see a better arrangement and the inclusion of a greater number of more critically selected practical procedures.

Oxidation-Reduction Potentials of Inorganic Substances in
Aqueous Solution. IUPAC-Selected Constants. By G.
Charlot, A. Collumeau, and M . J . C. Marchon. Butterworths, London 1971. 1st ed., 13 pp., bound E 3.50.
With the support of employees from the Laboratoire de
Chimie Analytique, Paris, and from the Centre National
de la Recherche Scientifique, G. Charlot et a!. in the Electrochemical Commission of the Analytical chemistry Division
of the IUPAC have compiled a collection of data that
should be useful to any inorganic chemist. The data refer
mainly to complexes with oxide, hydroxide, halide, azide,
cyanide, and thiocyanate as ligands. Complex redox pairs
with organic ligands are unfortunately not tabulated. It
is left to the reader to calculate these for himself from
the data given and from constants tabulated elsewhere
for complex equilibria.

Standard potentials (based on the activity a = 1) and formal
potentials (based on the concentration c = 1) are listed
separately: this takes into account the requirements of
thermodynamically correct terminology. Though the
majority of the potentials given are for 25"C, the corresponding temperature is given in every case. An important
advantage for comparison purposes is that the method
used for the determination of the literature value is also
This tabulation covers the literature from 1900 up to
December 31, 1967. The arrangement in alphabetic order
of the elements is based on practical requirements, though
it makes comparisons within individual chemical groups
more difficult. About a dozen half-cell reactions contain
errors of stoichiometry, and should be corrected with respect to the balance of particles and charges. Moreover,
the symbols Es (instead of En) for einsteinium and Md
(instead of Mv) for mendelevium should have been used.
To sum up, it may be said that this tabulation of about
100 redox potentials in a small volume should be a useful
addition to the existing collections of data.

The Identification of Organic Compounds. By S. Veibel,
G. E. C. Gad Publisher, Copenhagen 1971. 7th ed.,
xvi, 471 pp., numerous figures, bound Dk 1 15.-.
Six years after its last edition, this well-established book
is now available in its 5th English edition. The book contains the chemical methods for the detection and determination of organic compounds. The first section deals
with the testing of purity, and includes chromatographic
methods as one of its new features. The second section
contains the methods for the detection and determination
of the elements, while general methods for the examination
of organic substances are given in the third section. The
last and by far the largest chapter contains the methods
for the detection and determination of functional groups.
In comparison with the last edition, methods that have
proved less useful have been eliminated and new methods
have been introduced. The latter include in particular the
methods of titration in non-aqueous media. The book
ends with a table of a wide range of reagents in the required
concentrations and a large author and subject index.
It is undoubtedly difficult to bring B,. book that first
appeared in 1927 up to date by 'constant additions and
revisions. Nevertheless, this book is certainly useful and
can be recommended, as long as one is interested only
in chemical methods. However, the claim that can be
inferred from the title cannot be upheld when one considers
that spectroscopic methods, which are dominant today,
are practically ignored.

Organosilicon Derivatives of Phosphorus and Sulfur. Monographs in Inorganic Chemistry. By s. N . Borisov, M .
G. Voronkoo, and E. Ya. Lukevits. Plenum Press, New
1971. 1st ed., xiv, 343 pp., numerous

An element whose first organo derivatives were prepared to disprove Mendeleev's system, whose second
encounter with organic chemistry was motivated by the
idea of using organosilicon compounds for the study of
optical activity (which did not work either, at least not in
this way), and which only at the third attempt found a
