This will be useful to younger readers. particularly since such
relationships usually cannot be found in the literature.
The book, which has a subject index and is otherwise excellently presented, is a very good source of information on
“H. C. B.” chemistry. A broader outlook results from the fact
that the author has been practising chemistry for a long time
in company with many worthy colleagues. However, the subject
indicated by the title of the book is by n o means exhaustively
discussed. The book can be recommended to any critical
reader. No library should be without this excerpt from the
contemporary history of chemistry .

Three of the planned six systematic volumes of the new edition
of “Ullmann”, publication of which was started in 1972, are
now available; the first of the eighteen alphabetic volumes
has meanwhile also appeared. Despite the change of publisher
(the new edition is published by Verlag Chemie), the wellproven basic concept of the third edition has been kept
unchanged“]. The editorial board has wisely decided to revise
the work completely instead of continuing it in the form
of supplementary volumes. The latter possibility would have
had the advantage of giving a more up-to-date result, but
the unity and clarity offered by the new edition are probably
more important to most of those who use the work, since
true up-to-dateness can only be achieved by following the
latest original publications.
The present three volumes, together with the fourth volume
(Process Development and Plant Design), which has not yet
been published, are descended from Volume 1 of the third
edition. The enormous development that has taken place in
chemical process technology during the past 20 years is clear
simply from the greatly increased size of this systematic part.
This is true in particular of the theoretical grounding and
penetration of the field. For this reason the work as a whole
begins with a special volume on scientific principles. This
is followed by two volumes dealing with the unit operations
of process technology together with the associated equipment,
as well as general fields of process technology such as heating
and cooling, materials, and pressure and vacuum technology.
The volume on basic principles (Vol. 1 ) consists of the following
sections: Chemical Thermodynamics (53 pp.), Estimation of
Physicochemical Properties of Gases and Liquids (28 pp.),
Fluid Dynamics (35 pp.), Heat Conduction and Heat Transfer
(13 pp.), Diffusion and Mass Transfer (28 pp.), Chemical Kinetics (36 pp.), Dimensional Analysis and Similitude (16 pp.),
Principles of Chemical Reaction Engineering (75 pp.),
Statistical Methods in the Planning and Evaluation of Experiments (68 pp.), Optimization (58 pp.), Mathematics (194 pp.).
The essential contents of the individual sections are definitions
and explanations of the fundamental concepts and derivations
of the fundamental relationships. Examples are given to illustrate theoretical methods arising from these discussions; special mention may be made of the mathematical determination

of material values and the statistical planning and evaluation
of experiments.
The bibliographies at the end ofeach contribution are designed
primarily to enable the reader to obtain further and more
advanced information from monographs on the subject. All
the contributions (written by a total of ten authors, all but
one of whom work at universities) are characterized by clear
and impressive presentation; this gives the volume a wellrounded and unified character.
Whereas the first volume had no equivalent in the previous
edition, the next two volumes really are a new edition of
the previous first volume, i. e. a thorough revision.
Volume 2 contains the sections : Size Reduction and Classification (80 pp.), Mineral Dressing (62 pp.), Mechanical Separation Processes for Two-Phase Systems (105 pp.), Mixing
(63 pp.), Size Enlargement (31 pp.), Heating and Cooling
(143 pp.), Physicochemical Separation Processes (241 pp.).
Volume 3 follows with contributions on: Materials and Noise
Prevention (82 pp.), Pressure and Vacuum Technology (47
pp.), Conveying (54 pp.), Refrigeration and Cryogenics (67 pp.),
Electrolvsis(51 pp.). Photoreactions(l5pp.).Reactors(277 pp.);
thecontribution on reactors is furtherdivided into thesections:
Homogeneous Gas and Liquid Phase Reactions (34 pp.),
Liquid-Liquid and Gas-Liquid Reactions (40 pp.), Noncatalytic Reactions with Solids (70 pp.), Reactions on Solid Catalysts
(54 pp.), Electrothermal Furnaces (24 pp.).
The contributions are all divided into several subsections,
generally written by different authors. For example, the contribution on physico-chemical separation processes (Vol. 2) consists of the parts: Distillation and Rectification, Liquid-Liquid
Extraction, Absorption, Adsorption, Diffusion Separation
Methods, Evaporators, Sublimation, Crystallization, Fractional Crystallization from the Melt, Separation by Freezing,
Drying, Extraction of Solids. The number of authors who
have contributed to Volumes 2 and 3 (49 and 35 respectively)
is accordingly much greater than for Volume I; in the established Ullmann tradition, these are all acknowledged experts,
mainly from industry.
The contributions describe the particular principles and the
practical execution of the procedures for the sector in question.
The construction and operation of the equipment are thoroughly explained with the aid of illustrations; methods for
the calculation and design of equipment are also dealt with
in exemplary fashion.
In view of the extensiveness of the subject matter and its
division into individual topics, as occurs in Volumes 2 and
3, and indeed as is necessary for a thorough presentation,
overlapping has been unavoidable. One should also bear in
mind that the division of the material undoubtedly depended
in part on the authors who were available. The reviewer
nevertheless feels that a more rigorous subdivision would
have been possible in particular in the sections on “Heating
and Cooling” and “Reaction Equipment”, in the interests
of a more unified and better-balanced description of these
fields. In the section on Reaction Equipment, for instance,
roasting processes are certainly overstressed, above all when
one considers that they occupy almost as much space as
the contributions on heterogeneously catalyzed gas reactions
in fixed beds and in fluidized beds together. Reactors for
radiation-chemical reactions, apart from photoreactions, are
not discussed; this omission should be corrected in the alphabetic part. This is also to be recommended for the key words
“Storage”, “Aseptic Production Techniques”,“Tabletting” : the
first as a fundamental operation that is important for all
types of chemical plants, and the last two as processes that
are used e. g. in the packaging of pharmaceuticals.
However, these critical remarks are not intended in any way
to belittle the outstanding achievement of the editors and
authors. These three general volumes are indisputably the
most comprehensive and most up-to-date work in existence
on the field of chemical process technology as a whole; this
is true even as far as foreign literature is concerned. It is
worth mentioning that the new Ullmann also contains lists
of contents and indexes in English. The presentation, illustrations, and print are of outstanding quality. Each contribution
is followed by a clearly arranged list of references.
As in the previous edition, these general volumes will be
of immense assistance to anyone who is concerned with process
problems, both as a source of general information and as
a source of advice on special problems. The latter case will
particularly concern the practical engineer or chemist confronted with the question which process and which equipment
are most suitable for a given purpose. This question of the
choice of processes and equipment, which is not discussed
in the same depth in all the contributions of Volumes 2
and 3, should be treated on a broader basis in Volume 4,
which will be available shortly.

The result is a very useful literature compilation, which cannot
always be complete, owing to the width of the individual
fields. This Volume 4 unfortunately does not contain a chapter
on organometallic compounds of the elements of the second
main group. However, the editor B. J . Aylett assures us that
a chapter on this topic will be included in the above-mentioned
volume in the second series.
The work is not a pure list of highlights, nor does it have
the character of a detailed review. It adopts a reasonable
intermediate position, and it is pleasing to note that it contains
few printing errors. The presentation of the work is very
good, and it can be recommended to any organometallic
chemist as a literature survey.

The series “Inorganic Chemistry” comprises a total of ten
volumes and an index volume. Thefirst series contains important progress reports on work published during the period
from about 1967 to 1971. The second series, which is of
roughly the same size, is scheduled for 1974; it will contain
reviews of publications from the period 1971-1973. Further
series will follow at roughly equal intervals.
Volume 4 of the first series is divided into nine chapters,
which largely embrace the field of the organometallic chemistry
of the main group elements. The material is divided as follows:
Organoalkali Metal Compounds (author : P. Wesr): Organoderivatives of Zinc, Cadmium, and Mercury ( K . C . Bass);
Organoboron Compounds ( K . Niedenzu) ; Aluminum, Gallium, Indium, and Thallium ( J . B. Farmer and K . Wade);
Silicon, Part 1 (V. Chvalocsky) ; Silicon, Part 2 ( H . Biirger) ;
Germanium ( E . J . Bulten) ;Tin and Lead ( A . J . Bloodworth) ;
Organic Compounds of Arsenic, Antimony, and Bismuth
( J . P. Crow and W. R . Cullen).
In these nine chapters the authors report the most important
developments in the various fields during the years 1969 and
1970. The reports are based on 2608 literature references.
All earlier review articles and books dealing with the field
in question are generally also cited in the various chapters.
