liquid phases’‘ in Germany. Moreover, the content of the
book is placed in the proper perspective only when it is
considered that it is part of the ‘‘Series on Chemical Engineering”, for it deals cJmpiehensively and i n detail with
everything that seems to be of importance from the point
of view of the U.S. chemical engineer, but contains little or
nothing about the c h e m i c a l fundamentals of distribution.
For example, the chapters on “Prediction of Distribution”
and “Choice of Solvent” d o not discuss the question which
solvents may be particularly suitable for separating a mixture
of substances for chemical reasons, but contain graphic
and mathematical aids for estimating the separatory effect
to be expected for a given system of materials when the
equilibrium data are only incompletely known.
The book is the accepted standard work on this topic in the
U.S. American literature. The terminology coined therein -not always the best - has found acceptance in mineral oil
technology even beyond the U.S.A., so that study of the book
is the best introduction to literature on this theme. A few
chapters (physico-chemical fundamentals, determination of
the separatory effect - mostly via graphs or diagrams) are
recommendable as an educational text on account of the
clarity of the diction; others are hard to read, because far
some chapters up to two pages are required solely for the key
to the symbols used, because despite this other symbols occur
the meaning of which is unclear, and because some definitions
are insufficiently precise or even incorrect ( e . g . the quantity
A on p. 244). The book seems therefore rather inconvenient
for the purpose of rapidly finding answers to isolated questions.
The new edition is some 50 larger than the first edition of
1951; recent literature has been evaluated, and a short
chapter on laboratory methods has been inserted. New
examples from various fields - including inorganic chemistry
- have been added, even though the book is presented from
the viewpoint of the petroleum engineer (as shown, for
example, by the frequently inapt use of the terms “raffinate”
and “extract”). However, the problems discussed, including
mass transfer and fundemental questions related to apparatus
in particular, are presented i n such great detail that anyone
working o n separations by distribution - even inorganic
chemists - can read this book with profit.

Progress in Reaction Kinetics, Vol. 2. Edited by G . Portpr, in
cooperation with K . R. Jennings and B. Stevens. Pergamon
Press, Oxford-London-Edinburgh-New York-Paris-Frankfurt 1964. 1st Edit., V11 + 391 pp., numerous illustrs. and
tables, linen 6 4.4.0 (about $ 11.60).
Once again G. Porter has succeeded i n securing prominent
specialists to present excellent treatises on some important
aspects of kinetics research.
G. C . Fettis and J. H . Knox give a review (36 pp., 64 references) o n the rate constants of the reactions between halogen
atoms on the one hand and molecules of hydrogen, hydrocarbons, and chlorocarbons on the other. The results are
also discussed from the point of view of the methods involved. The fact that the reaction of hydrogen iodide is not a
prototype of a bimolecular reaction deserves mention even i n
a book review.
R . J. Cvetanotiic gives a comprehensive discourse (86 pp.,
147 refs.) on energy transfer via excited mercury atoms. His
formulation of the electron-deficient transition state involved
(p. 127) is interesting.
H . M . Frey deals with the quantitative aspect of carbene
chemistry (27 pp., 126 refs.). Insertion and addition reactions
of carbene and substituted carbenes are described.
In the “Kinetics of cis-trans-isomerizations” of olefinic systems, R. B. CunduN deals with a field that has been studied
with particular intensity within recent years (44 pp., I8 1 refs.).
The same remark applies to the “Kinetics of Anionic Polymerization and Copolymerization” by M. Swtrrc and J . Sn7id
454
(61 pp., 180 refs.). Both articles are characterized by their
complete coverage of important publications o n these sub,jects.
A review o n the “Rate Constants of Protolytic Reactions i n
Aqueous Solution” by M . Eigen, W. Kruse, G. Mnrirs, and
L . De Mnyer is necessarily a summary of Eigen’s publications.
This is preceded by a discussion of the maximum reaction rate
in solution. Regarding relaxation methods the reader is
referred to specialized publications.
Thechapter on “Reaction Rates of Some Haem Compounds”
by Q. H . Gibsori (12 pp., 67 refs.) gives an exemplary review
of the status of kinetic investigations on biochemical systems.
I n conclusion, a non-review article by R . M . h’oyes describes
the formal kinetic treatment of secondary reactions in a
general form. H e defines and discusses the limits of validity
of approximate solutions.
The final “Reaction Index” gives a list of more than 1000
reactions whose rate constants are discussed in the text. The
book is an indispensible part of the libraries of chemical and
physico-chemical laboratories. Its purchase for private use
can be recommended even to individuals who are working in
only one of the fields discussed.

The chemistry of the elements Si, Ga, and Sn has developed
enormously during the last decade, and silicon compounds
are in the forefront of this development. Here the author has
disregarded silicates, silicones, silicon methylenes, and complicated carbon compounds containing silicon as a hetero
atom in favor of simple compounds of silicon with other elements. This selection is particularly fortunate, since there is
n o comparable recent survey of this type, and since reliable
statements about the nature of the bonding involved can best
be made here. An introduction is followed by two chapters on
the Si-H bond (simple compounds and their reactions). The
third chapter deals with silicon halides. The fourth chapter
deals with the Si-C and Si-Si group of compounds, the fifth
chapter with those of Si and the elements N, P, and As, and
the sixth chapter with the compounds of Si and elements of
Group VI of the periodic table. Each chapter deals with the
preparation of characteristic compounds and their physical
and chemical properties, due regard being given to the results
of spectroscopic investigations. The seventh chapter summarizes the data on compounds which d o not fit well into the
simple scheme selected. The literature has been covered up to
1961. A valuable feature of the book is the inclusion of much
numerical data, e.6. energies of formation and bond lengths.
This book will prove a valuable companion to every chemist

Zone Electrophoresis in Blocks and Columns. By H . Bloemendol. Elsevier Monographs. Elsevier Publishing Co., Amsterdam-London-New York 1963. 1st edit., viii + 219 pp., 75
figs., 13 tables, linen DM 22.50 (about $5.65).
Analytical and preparative zone electrophoresis is an inseparable part of protein chemistry nowadays. Separations of
mixtures of similar proteins can be achieved on starch gels i n
an electrical field with a n accuracy that is equalled by practically no otker physical method. Bloemendal is therefore to be
congratulated for this description of conventional apparatus
for carrying out block, gel, and column electrophoresis (including continuous procedures), together with procedures for
applying them i n work with biological materials. The author
has intentionally disregarded electrophoresis o n paper or
agar-agar and also electrophoresis without a solid support,
since monographs on these topics hace already been published,
but he has included electrophoresis on columns with concenAngew. Chem. internut. Edit.
