Book Review Solid Acids and Bases. By K. Tanabe

код для вставкиСкачать
held in such high esteem by Emil Fischer that he suggested
an agreement regarding research programs. The missing
information can be obtained from an obituary by John
Read in J. Chem. SOC.1954,476. However, it is even difficult to gain a true picture of Iruine’s personality since the
authoress tends to idealize her husband in a rather uncritical manner, which disqualifies the book as source
material for future historical studies.
The book cannot therefore really be recommended to the
chemist who is interested in the history of his subject unless
he would enjoy reading a biographical report described
by the authoress as “an old-fashioned chronicle of an era
that is past.”

Solid Acids and Bases. By K. Tanabe.Academic Press, New
York-London 1970. 1st Edit., viii, 175 pp., numerous
tables and figures, bound $ 11.50.
The author of the present work is not content to “put new
wine in old vessels” since the topicality of his subject can
readily be assessed even from a glance at the bibliography
which contains mainly references from the last ten years
(up to 1970).Why is it that acid-base catalysis, well known
for a long time in the homogeneous phase, should again
arouse such great interest?
The main reason lies in the discovery of numerous refined
methods (color indicators, spectroscopic measurements,
adsorption from the gas phase or from solution, titrations
with substances showing acidic or basic reactions, etc.) for
determination of acidity and basicity (Hammett function)
and the concentration of functional groups on solid surfaces. Two chapters are concerned with these methods and
the important question of distinguishing between Bronsted
and Lewis acids is also discussed.
In two other chapters the author undertakes a characterization and systematic treatment of solids. At the beginning of his book he divides a large number of solids into
solid acids and bases and uses the largest chapter (chapter 4) for a treatment of the structure and the acid and basic
properties of the sites present on the surfaces of solids
(metal oxides and sulfides, mixtures of metal oxides, zeolites, metal sulfates and phosphates). The connection between catalytic activity and selectivity and the nature of
the surface is shown for reactions of widely differing kinds
(decomposition reactions, cracking, isomerization, polymerization, etc.) on catalysts having acidic, basic, or
bifunctional character.
good it is. The above text by Heyns has been thoroughly
prepared and betrays many years of lecturing experience.
Its information content and size approach those of a textbook. The many references to experiments in the text are no
doubt intended as suggestions for experiments during a
practical course rather than as a replacement for experimental demonstration.
The present study text is intended for students of chemistry, medicine, pharmacy, and biology from the second
semester onwards. The amount of material included is
probably rather overpowering for biologists and medical
students. For such an audience it would certainly have
been better to emphasize the more important points by use
of different types. For students of pharmacy and chemistry,
on the other hand, this text is highly recommended as
supplementary material to lectures and as an aid in preparation for examinations.

Chemical Analysis in Extractive Metallurgy. By R . Young.
Charles Griffin and Co., London 1971. 1st Edit., vii,
427 pp., bound f. 7.--.
The book deals primarily with the analysis of 42 technically significant elements, primarily metals, and is intended
mainly as a list of procedures for analysts working in the
field of nonferrous metals. According to the concept of the
author it should be “less comprehensive and more selective
than the excellent multi-volume treatises on analytical
chemistry, be more attuned to the routine industrial tempo
than is desirable in a university textbook, and to contain
more discussion of theory and interferences than is found
in the valuable analytical manuals of companies and trade
associations.”
The individual chapters usually open with rather general
statements about separation procedures, which are followed by more or less detailed instructions for gravimetric,
titrimetric, and, in some cases, also photometric methods.
Instrumental methods dominating the present industrial
scene are dismissed with brief comments that frequently
are devoid of real information content.
Overall the book fails to fulfil the stated aim of the author.
Only a few analytical procedures are described so precisely
that successful repitition is assured ; essential details are
frequently missing. Trivial and elementary analytical information also occupy considerable space. A general preference for time-consuming gravimetric methods grossly
contradicts the author’s intention to consider mainly fast
methods.
Both the scarcity of literature on this scientifically and industrially important subject and the presentation of the
book with its clear tables and illustrations make the work
a valuable aid for all who are concerned with heterogeneous
catalysis or wish to enter the field.
The book which contains 1200 references, exclusively to
English-language literature, can therefore only be regarded
as a relatively comprehensive survey but not as a really
useful tool for the analyst working in this field.

Practical Catalytic Hydrogenation.Techniques and Applications. By M . Freifelder. John Wiley and Sons Ltd., New
York 1971. 1st Edit., xxii, 663 pp., numerous figures,
bound f. 11.75.
The series of study texts including the present work presents
lecture manuscripts of proven value in somewhat modified
form. An experimental presentation which relies heavily on
the illustrative power of the experiments themselves can
only be incompletely replaced by a manuscript, however
Angew. Chem. internat. Edit. 1 Vol. I I (1972) / No. 7
Catalytic hydrogenation can certainly be regarded as a
particularly effective and reliable method throughout the
whole field of organic chemistry whose successful application to particular problems nevertheless requires adherence
