Book Review Grundriss der technischen organischen Chemie (Outline of Organic Chemical Technology) by A. Rieche

код для вставкиСкачать
tinuation of the four volumes originally planned was hoped
for. This volume represents a supplement to the first volume
(published in 1956) and contains chapters on methods
developed since that time, such as gas and thin-layer chromatography. However, it gocs far beyond the limits indicated
by the title, since, for example, methods of tissue and cell
culture are dealt with in an admittedly well-written chapter.
On the other hand, the intended function of the book is
again in question: is it intended to be a laboratory handbook
containing full working instructions or to be a treatise on the
theory of the methods and a working guide to the literature
containing the practical procedures? The contributions
alternate between onc conception and the other. In vicw of
the variety of authors involved in the task, it is, perhaps not
surprising that the heterogeneity criticized earlier is continued in the new volume. Nevertheless, at the same time
this is well atoned for by the high quality of most of the
chapters.
In view of thc fact that monographs of all sizes dealing with
particular analytical techniques (e.g. chromatography) are
now commonplace in every laboratory, it would be space
saving, in the reviewer’s opinion, if such themes were avoided
in general and only dcalt with where there is real necessity.
It is essential to get away from the idea that it is possible in
practice to produce a handbook that is both comprehensive
and short. In scientific writing today, the decisive question
is no longer whethcr the publication can be sold. What is
important is whether a new publication will prove a help or a

burden to the active scientist.
Grundriss der technischen organischen Chemie (Outline of
Organic Chemical Technology) by A. Rieche. S. Hirzel
Verlag, Leipzig 1961. 2nd Edit. XVIII, 549 pp., 151 illustr.,
bound D M 24.60 (about $6.25).
In the second edition of this textbook appearing five years
after the first [I], the choice and arrangement of the subject
matter has remained substantially unaltered. The latest developments in the field of natural gas and petroleum processing
are included. New chapters on organic dyestuffs, dyeing and
calico printing, tanning and leather manufacture, plant protectives, and explosives have been added. The textbook has
thus acquired greater scope, embracing almost the entire field
of organic chemical technology.
It is to be commended that the newer developments arising
from the switch-over from coal to petroleum and from acetylene to olefins as starting materials in industrial syntheses have
been taken largely into Consideration; e.g. the production of
acetaldehyde from ethylene, of butadiene from butane, and
of acetylene by pyrolysis of hydrocarbons.
The reviewer believes that, because of the bewildering number
of technical processes that are in existence, this book could
have given the student more precise differentiation between
purely historical processes (the discussions of which should
be severely restricted), processes in full-scale production, and
processes still in the development stage, and he suggests that
the dcscription of outdated processes, such as the hydrogenation of acetylene to ethylene, the production of ethylene
from ethanol, or of acetone from acetic acid, could be
shortened or entirely omitted. The detailed treatment of the
Fischer-Tropsch process and the hydrogenation of coal could
also be considerably streamlined.

In addition, condensation would be welcomed in the chaptcrs
on organic coloring mattcrs i n favor of the dyestuffs used at
present as opposed to the historical treatment given (natural
coloring materials).
In the Herz synthesis (p. 4X4), chlorination of the nucleus
also occurs. Thc formation oi‘bcnanthrone (p. 491) can be explained by the mechanism pi-oposed by Meerwcin. The constitution of diazo cornpounds (p. 496) is explained nowadays
in disfavor of Huntzsclz’s conception. Reactive dyestuffs
(p. 505) deserve a fuller dcscription in view of their importance. I n the scction on pigmcnt dyestuffs (p. 509), the importance of saturation vat-dycs and quinacridonc should bc
pointed out. Thc view of thc author, that new pigment dyes
have not been dcveloped, is not borne out by the large volume
of more recent patent literature. In the sphere of medical
preparations, arsenic compounds are now superceded. On
the other hand, it would be dLxirable to have an indication of
sulfanilamides as blood sugar depressants.
These critical comments are not intended to detract from the
positive impression convcyed by this book. In conclusion, it
can be stated that it offers the student a broad picture of
organic chemical tcchnology correct in all the important
fundamentals and can be rccommended to him as a basis for
the study of the subject.

Die quantitative Bestimmung der Alkaloide in Drogen und
Drogenzubereitungen (QudlltltatiVC Determination of AIkaloids in Drugs and Drug Preparations) by Otto-Erich
Schulz and F. ZymalkowsAi. Vol. 41 in the series “Chemical Analysis”, edited by G. fonder. Ferdinand Enke Verlag, Stuttgart, 1960, 1st edit., X, 295 pp., 27 illustr., 29
tables, cloth-bound DM 77. (about $20.-).

The quantitative determinatlon of alkaloids, particularly in
drugs, is an important field of pharmaceutical analysis, in
which the producer, dealer, and user are equally interested.
The difficulties involved in t hc actual dctermination of the
alkaloids are generally much less acute than those of their
initial isolation and purification. On the one hand, most drugs
contain a large number of alkaloids, which are closely related chemically, but of which only some are of interest from
the pharmaceutical point of vicw, and on the other, they may
be accompanied by a wide variety of other materials whose
presence frequently increases the difficulties of separation.
The first section of this monograph is general and covers the
principles of methods of isolation and determination. Besides
the classical methods of alkdloid extraction, methods employing column chromatography, ion-exchange, countercurrent distribution, and papcr chromatography are covered
in detail ; besides gravimetrlc and titrimetric methods of
determination, colorimetric, photometric, and polarographic
methods are dealt with. The \econd part is specialized and is
devoted to consideration of individual drugs. In each case,
the properties of the most important alkaloids and materials
accompanying them are first discussed in order to make the
proposed method of assay understandable. The following
descriptions of assay procedures are so detailed that reference
to the original work can nios(ly be dispensed with.
This well-prepared work fills d gap in the scientific literature
and should prove of consider.ihle value in all laboratories engaged in pharmaceutical analysis for gaining preliminary insight into proposed methods of determination.
