Nitration and Aromatic Reactivity. By J. G. Hoggett, R. B.
Moodie, J. R. Penton, and K . Schojeld. Cambridge University Press, London 1971.1st edit., xii, 246pp., f 5.-.
Of the aromatic substitution reactions, nitration has been
studied with particular thoroughness. It is not only of
central importance in preparative organic chemistry, but
has also played a decisive part in molding the development
and progress of theoretical chemistry. Full account is taken
of this in the present book. The authors have succeeded in
exemplary fashion in giving the reader a closer look at the
current problems in physical organic chemistry, using
nitration as an example. They show their deep knowledge
of the subject in their discussion of the relationship between
structure, reactivity, and selectivity of electrophilic nitration
reagents, in relation to nucleophilic substrates. Even more
praiseworthy is the exposition (the need for which has been
felt for a long time) on mixing and encounter controiled
reactions and their disguising effect on the selectivity of
chemical processes.
The contents of the book are arranged as follows:
1. Introduction ; 2. Nitrating systems: A. mineral ‘acids;
3. Nitrating s)stcms: B. inert organic solvents; 4. Nitrating
systems: C.miscellaneous(nitration with nitrogen pentoxide,
nitration cia nitrosation, nitration with nitronium salts in
organic solvents); 5. Nitrating systems: D. benzoyl nitrate
and systems formed from nitric acid and acetic anhydride;
6. The process of substitution. The remaining four chapters
are devoted to the topic ofnitration and aromatic reactivity:
7. Theoretical background; 8. Nitration of bases; 9.
Nitration of monocyclic compounds; 10. Nitration of
bicyclic and polycyclic compounds.
The book has author, subject, and compounds indexes and
gives an impressive survey of the literature up to 1970. It
can be recommended without reservations to any chemist
of modern outlook.

Handbuch der Analytischen Chemie (Handbook of Analytical Chemistry). Part 3, Vol IIIa. Quantitative Analysis,
Aluminium. By W. Fresenius and G . Jander, revised by
H . Bensch. Springer-Verlag, Heidelberg-Berlin-New
York, 1972. 2nd Edit., xix, 716 pp., 47 figs., bound DM
198.-.
With the appearance of the present edition, this well tried
handbook has been expanded by a further important
chapter. The author, who is a recognized specialist in
the field of the analysis of aluminum, must be congratulated on his splendidly comprehensive contribution (no
less than 2521 references!).
In addition to the two main sections on determination
techniques (550 pp.) and separation techniques (80 pp.), the
book contains an introduction to the principles of the
chemistry of the aluminum ion in aqueous systems and a
short section on special techniques, which consist essentially of techniques for the determination of aluminum
metal, e. g. in metal powders or dross, and the determination
of aluminum oxide in aluminum and its alloys and in iron
and steel.

The chapter on determination techniques is subdivided
into gravimetric, titrimetric, photometric, fluorometric,
nephelometric, polarographic, spectrochemical and radiochemicals methods, and deals not only with the usual
methods but also with a large number of other possibilities.
The chapter on separation methods is subdivided into techniques involving precipitation of aluminum itself, separation by precipitation of the accompanying elements, by
masking the aluminum or by complex formation,extraction
techniques, separation by electroiysis on a mercury
cathode, chromatographic techniques, and separation
by evaporation in a current of hydrogen chloride or
chlorine.
The material is concisely presented and contains a large
number of clearly formulated operating procedures, useful
notes being given wherever possible to indicate their
accuracy, the possibility of interference, and the range of
application. This is a genuine treasure house and no
analytical laboratory should be.without it.

Diffusion Data. By F. Wohlbier. Trans Tech Publications,
Clausthal 1971.1st edit., 269 pp., bound, $44.--.
“Diffusion Data” is a review of experimental results in the
field of migration phenomena in crystalline and amorphous solids, and also in liquids that are solid at normal
temperatures. Despite the brevity of the individual items
it is comprehensive, and the results appear only a short
time after their initial publication. Apart from work on
diffusion as such, there are reports on the isotope effect in
diffusion, on thermo- and electrotransport, ionic conductivity, permeation of gases, experimental methods for
determining these effects, etc. Consideration is given to
atomic transport processes in crystal lattices, along grain
boundaries or dislocations, on surfaces and interfaces,
and in thin films. The data are arranged in alphabetical
order of the matrix substance concerned for each material
grouping, e.g. metals and their alloys, semiconductors
oxides, halides, organic crystals, etc. In conjunction with
the author, subject, and subject field indexes, this breakdown enables the reader rapidly to find the information
he wants. The bibliography is also broken down by material
groupings.
The brief discussion on each article contains not only the
actual experimental data, which are often advantageously
supplemented by graphical presentations, but also information on the experimental method and the material used
and the author’s interpretation of the transport mechanisms, anomalies, erc. involved.
Vol. 5, No. 1 (1971) has an Appendix consisting of a
complete author, subject, and subject field index to the first
four volumes, which makes the present edition a miniature
work of reference in its own right. For anyone requiring
information on current results and experimental techniques
in the field of migration phenomena, “Diffusion Data”
offers the best possible method at present available for
obtaining such information quickly, conveniently, and
reliably.
