Kinetics of Precipitations. By A. E. Nielsen

код для вставкиСкачать
The literature has been completely cited until about 1960/61;
Russian and Japanese publications are notably well covered.
The subject matter is divided into three main sections, as in
the first edition: fundamentals, practical aspects, and applications. Mainly ion exchange resins are dealt with. In the
discussion of their applications, in contrast to the treatment
in the first edition, the author has now restricted his discourse to inorganic chemistry. This chapter makes up about
half of the book and describes the determination of the total
salt concentration, removal of interfering ions of opposing
charge, inorganic colloids and highly polymeric electrolytes,
isolation of trace components, separations of metals, chromatographic separation of anions, and inorganic qualitative
Since in many of the separations described, recourse must
still be taken to original publications, the reviewer thinks
it would be better in future editions to introduce tabulated
surveys for individual elements or groups of elements. This
wquld leave more room for standard practical procedures,
some of which might still have to be developed.
Nonetheless, the nature of the presentation in the text, figures,
and tables reveals that the author has full command of the
topic of his book. The work can therefore be recommended
to all who are occupied in any way with the analytical
applications of ion exchangers.

Kinetics of Precipitation. By A . E. Nielsen. International Series
of Monographs on Analytical Chemistry. Chief editors :
R. Belcher and L. Gordon. Vol. 18. Pergamon Press, Oxford-London-Edinburgh-NewYork-Paris-Frankfurt
153 pp., numerous illustrs., several tables,
1st edit., X
linen f2.0.0 (about S 5.50).
This monograph deals with the kinetics of crystal growth in
the situation where numerous crystallization nuclei are
formed simultaneously, as in most analytical and technical
crystallizations. The author has succeeded in covering the
whole of this complex field very comprehensively in 12 well
arranged chapters. This he achieves by neglecting to give a
detailed discourse o n the confusingly large variety of experimental reports o n this topic and by placing the theoretical
aspects in the forefront instead. Experimental results appear
only when compared with the results of theory or when
used for making premiscs. The relationships between the
formulae are developed lucidly and the most important
quantities are often expressed explicitly in various forms.
Aspects considered in detail include work of nucleation,
frequency of nucleation, diffusion-controlled growth, nucleation-controlled growth, and growth influenced by dislocations, combination of growth mechanisms, homogeneous
and heterogeneous nucleation, Ostwald ripening, growth
forms, .and adsorption. The reviewer considers the last
two chapters to be rather weak. Here the relation between
equilibrium form and growth form is not quite clear, and
that between surface energy and nucleation energy is unfortunately not described correctly. Nevertheless, this condensed and clear presentation of the subject will be of great
value to all aqsociated with the kinetics of crystal growth.

for it centers o n the erroneous idea that I-aminoalkenes are
more strongly basic than aminoalkanes. In their well presented review of “Synthetic Methods in the Carotenoid and
Vitamin A Fields” (109 pp., 335 refs.), 0. Jsler and P . Scltudel first describe chain-extension methods and syntheses of
symmetrical c8 to C30 intermediates, then the synthesis of

reductions o n the carotinoid skeleton. A table lists information o n total syntheses of C40 all-tuans-carotinoids. I n
the final article, “Coupling of Acetylenic Compounds”, G.
Eglinton and W. McCrae review methods for linking two
acetylenic compounds t o give 1,3-diynes. In addition to the
classical symmetrical coupling of acetylenes in the presence
of copper salts, much attention is given t o the unsymmetrical
coupling of one acetylene unit with a bromoacetylene in the
presence of CuzC12, a technique discovered in 1957. The
terse and well arranged presentation is supplemented by
extensive tables, 232 references (unfortunately not in alphabetical order), and descriptions of practical preparations.
The literature has been reviewed up to 1961. Addenda indicate the rapid developments in these fields, but also the
length of time that has elapsed between submission of the
manuscripts and the appearance of the book.’This is another
successful volume of highest quality and appearance in this
admirable series.

The Ring Index, which appeared in second edition in 1960,
is now extended with two supplementary volumes, in which
new ring systems described in the literature between January
Ist, 1957 and December 31st, 1961 are recorded. As emphasized in the foreword, the two volumes make a claim to
absolute completion, thanks to close cooperation with the
indexing staff of the Chemical Abstracts Service, and thus
not only give reliable information on the all-too-frequently
intricate nomenclature, but also indicate whether a ring
system is alieady known or not. Together with the basic
volume, the work has thus now catalogued 11524 ring
systems. It is therefore hardly necessary to point out its value.
Supplement I1 contains the first index of rings with heteroelements (with the exception of rings having only N, 0,
and/or S in addition to carbon). It also contains the complete
subject index for all three volumes, in which errata are also
Chemists have become accustomed to expect exceptionally
high standards from the Chemical Abstracts Service, and the
Ring Index completely fulfils these expectations.

Techniques for the Use of Radioisotopes in Analysis. A
Laboratory Manual. By D . A . Lambie. General and
Industrial Chemistry Series. Edited by H. M . Bunbury.
E. and F. N. Spon Ltd., London 1964. 1st edit. VI + 135
pp., numerous figs., linen E2.0.0 (about $ 5.50).
It is the aim of this book to acquaint its readers with the
applications of radioactive materials in analytical chemistry
and to give some indication of special practical procedures
and measuring techniques. The author begins with descriptions of radiometric procedures. Here the accent lies o n
isotope dilution analysis, the use of radioactive reagents,
and activation analysis, less attention being paid, for example,
t o Hevesy-Paneth analysis, which is so important in biochemistry, pharmacology, and agronomy.
