Book Review Practical Manual of Gas Chromatography. Ed. by J. Tranchant

код для вставкиСкачать
volume one finds many differences from the earlier conception of Gmelin’s Handbook. The most important, in the
reviewer’s opinion, appears to be the successful abandonment
of the historical but long outdated division into an inorganic
and a n organic section. A considerable part of the book is
devoted to the organoruthenium compounds. If the same
procedure is followed in future volumes, the value of “Gmelin” to the chemist will be greatly enhanced. Even a quick
glance through the present volume gives the impression that
it is a chemical reference book, and not merely a collection
of physical constants, as many of the earlier volumes seemed
t o be.
Another innovation is the abandonment of the earlier, often
excessively rigid arrangement in favor of a chemically more
logical classification. Salts of complex acids of ruthenium are
now dealt with under the various nonmetals. LiRuF6, for
example, is to be found in the section on “Ruthenium and
Fluorine“.
Finally, a very welcome change is that the present volume
almost attains the currency of progress reports. The literature
is completely evaluated up to the end of 1968, and many
important publications from 1969 are also taken into account.
The first two main sections of the volume deal with the properties of the element and its alloys. Ruthenium, which was of
no special importance in industry a relatively short time ago,
has rapidly grown in importance during the past few years.
It is a n efficient catalyst in many hydrogenation reactions,
and the nuclear chemist is concerned with its isotopes as fission products of uranium and plutonium, while some of its
alloys have superconducting properties.
The third main section describes the compounds of ruthenium. Considerable space is devoted to the discussion of the
very numerous nitrosyl compounds. This is followed by a
description of the compounds with neutral and inner complex
forming ligands, the carbonyl compounds, and the organometallic compounds of ruthenium.
A further innovation is found at the end of the volume in the
form of a n alphabetic subject index and a formula index for
the ligands, which make it much easier t o find groups of
compounds and individual compounds.

Zahlentafeln zur Massenspektrometrie und Elementaranalyse
(Numerical Tables for Mass Spectrometry and Elemental
Analysis). By G . Ege. Verlag Chemie, Weinheim/Bergstr.
1970. 1st Edit., xxvi, 352 pp., 356 tables.
The determination of empirical formulas from elemental
analyses is made much easier with Ege’s “Zahlentafeln
zur Elementaranalyse” (Numerical Tables for Elemental
Analysis). However, if a n analysis is not exact, several
possible formulas have to be considered; for example, the C
and H analytical values of homologs are often situated so
close together that i t is impossible to decide in favor of one
or the other compound. In such cases i t is possible t o reach
a decision on the basis of the molecular weight, which can
be determined mass-spectrometrically.
Acknowledging this fact, Ege has now expanded his original
Tables into their present form.
To keep the volume of the material within reasonable limits
the tables are restricted to carbon compounds with not more
than 40 carbon, 6 nitrogen, 12 oxygen, and a n appropriate
number of hydrogen atoms. On the whole this should prove
adequate. The numerical tables encompass compounds
with molecular weights from 16 to 845 arranged according
to increasing mass.
The idea of grouping the theoretical analytical values into
groups of ten is commendable, since i t greatly facilitates
rapid location of the empirical formulas.
In addition, one column gives the exact molecular weight
of each compound, so that the tables can also be used t o

determine empirical formulas with the aid of high-resolution mass spectra. In such cases elemental analysis becomes superfluous. Data on double bond equivalents constitute another welcome feature.
In contrast, the data on the intensity ratio of M+ and (M
+ 1)+peaks could well have been omitted, since in practice
the intensity ratios of M+ and (M + 1)+ions obtainable
from spectra are too inaccurate, a t any rate in the case of
compounds of higher molecular weight, to enable useful
conclusions to be drawn.
Nevertheless, this point in no way detracts from the value
of the tables, which can be warmly recommended to all
laboratories engaged on the investigation of organic comGerhard Spiteller [NB 910 IE]

Rechenseminar in physikalischer Chemie. (Problems in Physical Chemistry). By K . Torkar. Friedr. Vieweg u. Sohn,
Braunschweig 1968. 1st Edit., xii, 172pp., 48 figures, 38
tables, bound D M 9.80.
There are a considerable number of books dealing with
physicochemical calculations. These generally list the laws
of physical chemistry in a logical order and make use of them
as a basis for examples of simple calculations. K . Torkar
follows a n entirely different plan. He confines his book to
four problems:
1. Calculation of the pressure relations in a n autoclave. 2. Calculation of a chemical equilibrium. 3. Boiling diagrams.
4. Chemical reaction kinetics.
Under these headings he deals with 1) the formation of boehmite in a n autoclave or a n automobile COz fire extinguisher,
2) the reduction of chromium oxide by graphite or the conversion of carbon monoxide with steam, 3) the benzenetoluene system or the A-B system in general, and 4) reactions
of the types A +products, aA + 6B +products, or H2 + Br2
+ 2 HBr.
The author thus starts with concrete problems from practice
and explains the calculation procedure for the examples
named in the smallest detail. He compares the various calculation methods, indicates where the necessary numerical
values are to be found, and compares the data from different
tabulated values. The clarity of presentation is improved by
tables and graphs.
This book offers the student a bridge between formula and
application, and should encourage the teacher to hold similar
problem seminars.

Practical Manual of Gas Chromatography. Ed. by J .
Tranchanf. Elsevier Publishing Company, AmsterdamLondon-New York 1969. 1st Edit., xix, 387 pp., numerous illustrations, bound, Dfl. 85.-. English translation
of the second French edition.
When a book on chromatography is translated from the
French into English and joins the long ranks of works already published in English in this field, it is only natural t o
wonder whether the translation was simply motivated by the
existence of the wider readership, or whether this readership
may itself derive some benefit. The far-reaching and most
welcome exclusion of theoretical ballast - a n intention already proclaimed by the title- as well as the typically Gallic
conciseness and precision of thepresentation add up to a positivereply to thelatter question. The content of the book and
its points of emphasis can be conveniently indicated by enumerating the titles and numbers of pages of the nine chapters contributed by six authors: 1. Principles and retention
values (11 pp.); 2. Isothermal-isobaric chromatography
(15 pp.); 3. Programmed chromatography (18 pp.); 4. Apparatus (37 pp.); 5. Columns (73 pp.); 6. Detectors (40 pp.);
7. Qualitative analysis; separation and identification (39
Angew. Chem. internat. Edit. / Vol. 9 (1970)
No. I1
pp.); 8. Quantitative analysis (32 pp.); 9. Applications
and techniques (92 pp.). The emphasis of the book is
quite clearly on practical aspects. Nevertheless, all the
important equations derived from theory are included in
the most concise possible form. It would be wrong to regard
this merely as a dutiful exercise in theory, since important
practical conclusions are almost invariably derived from
the relationships. The two chapters on columns and applications merit special mention. Containing 263 and 809
literature references respectively, they not only provide a n
excellent survey but represent well-balanced and selfcontained treatises containing all the essential details.
Happily, there is none of the overlapping all t o o often observed in multi-author volumes. All the authors use the
same symbols which are collected together in a single list.
I t is unfortunate that out-of-date statements, now recognized as incorrect, are made in the discussion of the van
Deemter equation o n p. 23, in connection with mass transport in the mobile and the stationary phase. This is evidently due to the fact that the author of this chapter has relied
o n a (cited) paper whose experimental conditions were inappropriate to the theoretical conclusions based upon them.
In its nine chapters the book presents all the essential points
of gas chromatography. I t is particularly suitable for all
those who are daily confronted by analytical and experimental problems of gas chromatography, and can be recommended as a really excellent work.

Methods in Free-Radical Chemistry. Edited by E. S. Huyser.
Marcel Dekker Inc., New York 1969, 1st Edit., Vol. 1:
208 pp., numerous illustrations, bound $11.75. Vol. 2: xi,
242 pp., numerous illustrations, bound $12.75.
Since the publication of C. Walling’s book “Free Radicals in
Solution” in 1957, such extensive progress has been made in
this branch of chemistry that it would no longer be possible
for a single author to present a comprehensive treatment. As
in other fields, therefore, monographs in free-radical chemistry are being replaced by progress reports covering a limited
area. The present new series can consequently claim a place
of special importance alongside “Advances in Free-Radical
Chemistry” [I]. A wide selection of the results of work carried
out in free-radical chemistry over the past twelve years is
discussed in a total of five sections by young authors working
in this field.
The first two chapters (Free Radical Study by Electron Paramagnetic Resonance by L. Kevan, 35 pp.; Free Radical and
Photochemical Reactions by D . C. Neckers, 44 pp.) are dominated by the discussion of the methods and their theoretical
principles on the basis of selected results. Their value lies in
the concise and lucid survey and in the references to the original literature. The sections “Free-Radical Chlorinations”
( M . L. Poutsma, 114 pp.), “Free Radical Brominations” ( W .
A. Thaler, 106 pp.), and “Thiyl Radicals” ( R . M. Kellog,
120pp.), o n the other hand, deal systematically from the
preparative and mechanistic standpoints with free-radical
substitutions and additions of free radicals. The important
relations between structure and reactivity are clearly recognizable from the numerous tables and diagrams. These chapters undoubtedly constitute the more valuable part of the
present work, since the literature, which would now be very
difficult to scan, is reviewed critically and comprehensively up
to the latest position.
In presentation and quality, the two volumes may be regarded
as supplements to Walling’s classic work. They should therefore find a place in every library and are especially recommended to all those who are interested in free-radical chemistry.

Laser -man
Spectroscopy. By T. R . Gilson and P . J .
Hendra. Wiley-Interscience, Division of J. Wiley and
Sons, New York 1970. 1st Edit., ix, 266 pp., numerous
illustrations, bound, 90s.
Although laser light sources have considerably simplified
the techniques of Raman spectroscopy, the term “laser
Raman spectroscopy” is no more appropriate than “Nernstlamp infrared spectroscopy”. This is one of the faults of
the present book, which is meant to be “an introduction to
Raman spectroscopy with particular emphasis on the developments resulting from the use of laser sources”. It is
divided into the following sections: 1. Introduction (20 pp.),
2. Experimental (40 pp.), 3. Raman Intensity and Depolarization Ratios (23 pp.), 4. Single-crystal Raman Spectroscopy (58 pp.), 5. Raman Spectra of Gases (11 pp.).
6. Powders, Liquids and Solutions (13 pp.), 7. Polymers
(17 pp.), 8. Miscellaneous Raman Experiments (15 pp.),
9. Sources of Information (3 pp.). There are two appendices, one devoted to lasers (I, 6 pp.) and the other to
“Results from Group Theory” (11, 47 pp.).
The first four chapters are instructive and useful. The
beginner, however, would profit more from Chapter 4 and
Appendix I1 if examples had been treated in detail and
knowledge of the original work had not been presupposed,
as is the case o n pp. 109-123. The later chapters show evidence of unquelled enthusiasm over laser light sources
(“Laser has revolutionized the study” (of polymers) p. 166).
One learns a great deal about the successful recording of
individual spectra but not enough about how useful this is.
An unexperienced reader would doubtless get the impression that Raman spectroscopy was a very new method and
that a large store of experience in the field of “mercury-lamp
Raman spectroscopy”, as collated for example in the books
of Kohlrausch, Herzberg, and Siebert, did not exist. The
book is also disappointing for the organic chemist. Only one
page (155) is given to structural determination and there are
only nine lines (p. 165), without references, o n his main
concern, the detection of compounds whose vibrations in
the infrared are t o o weak. The reader is told nothing of the
important problem of appropriate sample preparation and
the dependence of intensity o n the grain size in powders.
Chapter 9 makes n o mention either of the very useful DMS
Reference Service “IR Raman Microwaves” which has
been operating since 1963, or of the spectra collections of
the API and in Landolt-Bornstein. Printing errors are rare.
The book would be more useful for beginners and for
specialists if the last chapters in particular were thoroughly
revised.

The Halides of the Lanthanides and Actinides. By D . Brown.
John Wiley and Sons Ltd., London-New York-SydneyTokyo-Mexico City. 1968. 1st Edit., x, 280 pp., numerous
illustrations, bound, ca. D M 43.--.
Until recently only two review papers have been available o n
the halides of the f transition elements, namely one on the
lanthanoid halides [IJ[*l and one o n the actinoid halides [21[*1.
D . Brown, who is himself a n authority in the field of the
actinoid and lanthanoid halides, has now attempted to
present a comparative description of the halides of all the f
transition elements. This attempt may be regarded as
highly successful. One’s only regret is that the halides of the
transcurium elements were discovered too recently to be
included in this book.
