AcetonedicarboxyL acid and its derivatives are formed in high
yield when ketene and phosgene react in a suitable organic
solvent at -30 to + 5 0 T with molar ratio of total ketene:
total phosgene ~ 2 . and
0 the product is allowed to react with
a compound containing active hydrogen, e.g. with an alcohol.
The acetonedicarboxylic esters prepared by this process can
be converted into citric acid or citrates by a cyanohydrin
synthesis and subsequent hydrolysis. [DOS 2409 342; Akzo

Aromatic polyamines such as ( 1 ), suitable for the production
of polyurethane plastics with improved tensile strength, are
obtained by reaction of (i) compounds containing at least
one tertiary nitrogen atom and at least two hydroxyl groups
and with molecular weights within the range 119 to lo00
with (ii) isotoic anhydride in maximally equivalent amount.
Transparent plastics reinforced by glass fibers can be obtained
from 5-50 wt.-U/, of glass fibers or glass beads and 95-50
wt.-% of a mixture of at least two compatible thermoplastic
materials whose proportions have been so assigned that the
refractive index of the mixed plastics and the glass fibers
is less than 0.002. Mixtures with poly(methy1 methacrylate)
and styrene-maleic anhydride copolymersare described. [DOS

Aziridines (3) are obtained on reaction of olefins ( 1 ) with
N-haloamines (2). R 1 to R4 represent H, alkyl, cycloalkyl,

This is the first of the alphabetically arranged volumes constituting the main part of the new (4th) edition, as in previous
editions of “Ullmann”[’]. As in the thematic part, the text
in the alphabetical volumes has been completely rewritten.
However, the general concept has been retained, i.e. the main
emphasis is on industrial methods of production and related
problems. The presentation has become more terse than previously which was a necessity in order to accommodate the
increased amount of material relating to new products and
processes within a work of reasonable size. At the same time,
the new layout (two columns on each page and more
pronounced optical subdivision) has improved the clarity of
Under the various key words the sub-sections on properties,
occurrence and raw materials, preparation, quality, storage
and transport, uses, economics, toxicology, are accompanied
by a special section on the problems of liquid and gaseous
effluents. Each entry is followed by a bibliography for further
information, divided into surveys and specialized references.
Cf. Angew. Chem. internat. Edit. 13.423 (1974).
Pharmaceuticals are particularly well represented in the key
words in this volume, together with alkaloids (57 pp.), analgetics (25 pp.), antibiotics (60 pp.), and antihistamines (14 pp.).
The raw materials include ammonia (70 pp.), acetylene (29
pp.), and acetaldehyde (13 pp.), and of the metals there is
aluminum (including alloys and compounds, 112 pp.). Other
large entries are for acetone (18 pp.), aliphatic aldehydes (24
pp.), alcohols (including polyhydric ones, 33 pp.), amines (aliphatic 19 pp., aromatic 10 pp., aniline 1 1 pp.), and anthraquinone dyes (62 pp.). Recognized industrial experts are responsible for the individual key word entries ; the sections

on toxicology are written by H . Oettel (Ludwigshafen), and
many of those on economics by L. Franke (Frankfurt/Main).
With the appearance of this, the first, new alphabetical volume
it can be stated that in its new edition “Ullmann” retains
its unbeaten record as a handbook of technical chemistry
in respect to both the quality of its contents and to its lay-out.
Particular credit should go to the editors, who, in spite of
the large number of authors, have preserved the pleasant
and homogeneous presentation.

Die Struktur der Atome und Molekiile (The Structure of Atoms
and Molecules). By J . Barrett. Translated by M . Ziegler.
Verlag Chemie GmbH, Weinheim 1973. 1st Edit., x, 348
pp., 205 figures, 62 tables, paperback, DM 38.-.
The book leads from the particle-wave dualism of photons
and electrons to atomic structure and the periodic system.
The major part of the work is concerned with bonding in
diatomic molecules and gives a detailed treatment of Walsh
diagrams and the electron pair repulsion model. The whole
is rounded off by a chapter on rc-electrons and bonding in
solids and transition metal complexes.
The text is intended for first-year students and for teachers
who want an introduction to theoretical chemistry that does
not involve complicated derivations. Such readers demand
a clear text in which simplicity is not achieved at the expense
of correctness, and the important point to note is that since
most of today’s introductory chemistry books contain increasingly longer and better theoretical chapters, a book devoted
solely to theory must offer some advantages over the general
chemistry textbooks.
Unfortunately, this is not true of the book in question. The
observant reader will find so many mistakes that its usefulness
for students must often be questioned. For example, already
on page 3 the electrostatic nature of nuclear forces leads
to serious fears about the stability of our world, whereas
the nucleus and the electrons are held together by “nuclear
forces”. The translation is not particularly careful; for example,
we find “virtuelles Vakuum”, “degenerierte d-Orbitale” and
“nicht miissen” (for “must not”). This type of mistake, whether
trivial or grave, could be easily removed, but the language
mastery of either the author or the translator seems inadequate
for the conceptual difficulties of modern physics; for instance,
on page 48 it is interchangeably asserted that the wave nature
of electrons should be understood as statistical and non-statistical.
It is true that such mistakes and inaccuracies occur mainly
in the first part, but it seems dangerous to burden beginners
or other readers with them, particularly as this book may
remain the only one on theoretical chemistry that the reader
works through.
It should not be overlooked that the chemical part, in particular the last two chapters, is considerably more successful,
but the book cannot really be recommended until it has
received more careful-and editorial-revision.
Finally, some suggestions may be permissible. In recent years
quantum-chemical calculations have been used increasingly
in organic chemistry, so that a new edition should contain
chapters on the Woodward-Hoffmann rules and on Hiickel
theory. Also, photoelectron spectroscopy could be used as
convincing support for the shell structure of atoms and as
an experimental basis for the introduction of the M O model.
