Book Review The Chemistry of Non-Aqueous Solvents. Vol. 1 Principles and Techniques. Edited by J. J. Lagowski

код для вставкиСкачать
The part containing the tables is divided into two major
groups. The first deals mainly with substances in which only
the protons are capable of nuclear resonance, or in which
only proton resonance was measured, and the second,
relatively small, group contains data relating to nuclei other
than H. Inorganic substances and polymers are not considered except for isotactic polystyrene. The tables contain
the nuclear resonance parameters (chemical shift and coupling constants) of the particular substance, with the solvent
used, its concentration, and the literature reference. Only
those substances are listed whose spectra had been accurately
evaluated. The literature has been included up to 1966.
The alphabetical division into 88 basic substances and their
derivatives is very easy to refer to but in some cases a little
confusing. The tables under the heading ‘anthracene’ or
‘naphthaIene’ d o not contain all the data on thesecompounds;
the reader still has t o refer to the voluminous chapter on
benzene, under the subheading of ‘condensed aromatics’.
Numerous benzo compounds are listed under ‘benzene’,
while others - like benzimidazole, benzofurazan, etc. - are
listed under their own names. However, all the substances
are easily found in the subject index.
This work has been printed o n good, strong paper - a
necessary precaution if frequent use is envisaged. I t will be
very useful to anyone engaged in the practice of nuclear
resonance spectroscopy, not least because he can rely o n the
author’s critical treatment of the literature.
This work should be brought up to date from time to time.
Perhaps the recently published data on polymers could then
also be taken into account.

The Chemistry pf Non-Aqueous Solvents. Vol. 1: Principles
and Techniques. Edited by J . J. Lugowski. Academic Press,
New York-London 1966. 1st Edit., xi, 403 pp., 18 figures,
6 tables, $ 16.50.
This book covers the more important aspects of reactions and
physical measurements in non-aqueous media - including
theoretical fundamentals - as well as the methods generally
used in investigations in low-boiling media and molten salts.
The following topics are treated: 1. Lewis acid-base exchange
in polar non-aqueous media (I). W. Meek); 2. Solvation of
electrolytes and solvent equilibria (E. Price); 3 . Acid functions in amphiprotic media ( R . G . Bates); Electrode potentials
in non-aqueous solvents ( H . Strehfow); 5. Solvent extraction
of inorganic substances (L. J. Kutzin); 6. Experimental techniques for low-boiling media (J. Nassler); 7. Experimental
techniques for the investigation of molten salts (R. A . Bailey
and G . J. Janz).
The first chapter is written in a fluent and easily understandable style. All essential aspects and modern points of view are
discussed. The reader is first familiarized with the out-ofdate concepts (e.g. SOClz as electrolyte in liquid SOz), which
are appropiately corrected in another part of the book. This
consideration of the historical course of the topic under
review is a n attractive and interesting feature of the work.
The reviewer would, however, have preferred the text to have
been based o n more modern and up-to-date knowledge and
the historical development to have been brought more into
the margin.
Section 2 contains a precise and clearly arranged treatment
of the influence of solvation on ionization equilibria. Modern
techniques of investigation are taken into consideration, e.g.
N M R measurements for the evaluation of interactions between cations and solvent molecules.
Section 3 is somewhat exacting and demands a great deal of
the reader. For example, the reviewer is of the opinion that
Zzmaifov’s ideas for the derivation of the solvation energy of
the proton is treated far too briefly. However, it must be
emphasized that the section as a whole is very clearly written.
Section 4 is written with remarkable didactic skill. Those who
are acquainted with the fundamentals of electrochemistry
and thermodynamics will have very little difficulty in under-
962
standing this contribution. The reader is given such a n excellent and impressive survey of the measurement and evaluation of electrode potentials in non-aqueous media that he
has no need to refer to the original literature.
The author of Section 5 has been confronted with the difficult
task of working through the extensive amount of original
literature concerning the separation of substances by distribution between two solvents. He has, however, succeeded in
compiling a representative review of the principles of the
many methods presently being used.
Section 6 is of immense value to all chemists who are concerned
with, or are likely to concern themselves with non-aqueous
solutions. The techniques used for preparation of solutions
are described mainly for lower-boiling media. Particular
interest attaches to solutions of solids o n which physical
measurements or chemical reactions are to be carried out.
All the physical methods that have become of importance in
the chemistry of non-aqueous solvents, e.g. polarography,
Raman spectroscopy, etc., are so treated that one can perform experiments as a rule without further ado, mainly
because of numerous and well illustrated figures of apparatus
and experimental set-ups that have been included.
The experimental side is also to the fore in Section 7; however, for a complete understanding of the fundamentals of
processes the necessary theoretical explanations are also
included. Methods for the determination of magnetic susceptibility, electrochemical and spectroscopic methods, and
methods for the investigation of transport phenomena are
treated, as are also and techniques such as calorimetry cryoscopy. Adsorption chromatography and chemical reactions
in molten salts are also dealt with.
All sections are supplemented with a fully comprehensive
bibliography. This work, which will appear in several
volumes, has closed a gap in the “secondary literature”. For
this reason, our thanks goes out to the editor, who has made
a name for himself particularly through his investigations o n
solutions in liquid ammonia. All chemists with a n interest, or
potential interest, in the field of non-aqueous solutions will
welcome the appearance of this work.

Halogen Chemistry. Edited by V. Gutmunn. Academic Press,
London-New York 1967. Volume 2: 1st Edit., xii, 481 pp.,
many figures and tables, 115 s; Volume 3: 1st Edit., xiv,
471 pp., many figures and tables, 115 s.
In this three-volume work on halogen chemistry the editor
gives a review of the present-day position of the subject. Unfortunately, the date of publication chosen is somewhat late,
for a number of the topics dealt with have recently been
treated in standard text books of fluorine chemistry and of
inorganic chemistry.
Volume 2 is concerned primarily with preparative chemistry
and with covalent halogen compounds; halogen oxides and
halogen acids have, however, been rather neglected.
Compounds of halogens with elements of the 3rd and 6th
main groups are likewise unconsidered.
This volume contains the following chapters: 1. SulfurNitrogen-Halogen Compounds (0.Glemser and M . Fild);
2. Fluorophosphoranes ( R . Schmutzler); 3 . Halides of Arsenic
and Antimony (L. Kolditz): 4. Inorganic Silicon Halides
(E. Hengge) ; 5 . Organoelement Halides of Germanium, Tin,
and Lead (J. Ruidich. H. Schmidbuuer, and H . Schumann);
6. Equilibria Involving Halide Complexes in Aqueous Solution (G. P . Haight jr.); 7. Halogenation and Halogen Exchange in Fused Salt Media ( N . R. Thompson and B. Tittfe);
and 8. Covalent Oxychlorides as Solvents (V.Gutmann).
The authors of the individual articles, who are undoubtedly
experts in their fields, have all contributed to the development of halogen chemistry by their own work.
In the first five chapters, structures, fluorine magnetic
resonance data, and a number of reaction mechanisms are
given, in addition to chemical properties and reactions. The
