of the sections on CrC13 hydrates and aqueous solutions
of CrC13, which give occasion to deal comprehensively
with the isomerism of the CrCI3 hexahydrates ([Cr(H20)&13,
[CrCf(Hz0)5]Cl~-HzO,[CrC12(H20)4]CI.2HzO) and the other
hydrates of CrC13 (decahydrate [CrC12(H20)4]Cl.6 H20, tetrahydrate [CrC12(H20)41CI, and trihydrate [CrC13(H20)3]).
The section on the s u l f u r compounds of Cr deals with the
sulfides and sulfates, such as CrS, Cr2S3, CrS04, Crz(S04)3,
and H2[CrO3(S04)] (“chromosulfuric acid”). Particular attention is paid to chromium(II1) sulfate c r ~ ( S 0 (hydrates,
~)~
acid suffates, basic sulfates; problems of constitution), owing
to its importance in chrome tanning.
The compounds of chromium with b o r 0 n include chromium
borides (Cr4B, CrzB, CrsB3, Cr3B2, CrB, Cr3B4, CrB2, and
Cr2B5) and chromium borates. Of particular interest here are
the data o n sintered hard metals based on CrB, since these
alloys have recently become technically important.
The section o n c a r b o n compounds of Cr includes accounts
of the chromium carbides Cr23C6 (LLCr4C”),Cr7C3 (“CigCz”),
and Cr3C2, chromium hexacarbonyl Cr(C0)6, chromium
carbonates, cyanides, and thiocyanates, and o n chromium
salts of carboxylic acids (formates, acetates, propionates,
oxalates, malonates, tartrates, and citrates). Special mention
should be made of the review on the preparation, properties,
and derivatives of chromium hexacarbonyl, and on the
chromium(II1) acetates, which are important tanning agents.
Among the p h o s p h o r u s compounds of Cr, the phosphides
Cr3P, CrzP, CrP, Cr2P2, and CrP2, the chromium(II1) phosphates CrPO4.nHz0, and adducts of chromium and phosphorus halides, such as CrC13.PCls = PC14[CrC14] are discussed.
in particularly important cases; but this is only a makeshift
remedy, which cannot replace exhaustive collation of the
literature un to the time of publication of the volume. It must
therefore be urgently requested that the decision taken in
1961 to introduce a “progressive closing date for literature
screening” (complete reportage up to the year of publication
of the volume in question) should be realized as soon as
possible.

Handbuch der Papierchromatographie (Handbook of Paper
Chromatography). Edited by I . M. Hais and K. Macek.
Gustav Fischer Verlag, Jena 1963. Vol. I: Basis and Techniques. Translated from Czechoslovakian into German by
J. Liebster. 2nd Edit. xv + 1069 pp., 235 illustrs., 178
tables, cloth, together DM 72.40 (about $18.50). Vol. 111:
Bibliography 1957-1960 and Applications. 1st Edit., xix +
700 pp., cloth, D M 40.90 (about $10.25).
Although since the appearance of the first edition the importance of paper chromatography has declined in favor of thinlayer chromatography, this consistent and painstaking revision of the standard handbook proves to be an important
production. The additional procedures developed during the
past five years in numerous laboratories, and not least in the
author’s own, have been harmoniously worked into the original highly successful work. The 225 pages of the general part
in the first edition have been expanded to 263 - even though
paper electrophoresis has been entirely neglected - and the
specialized part has increased from about 500 pages to 640.
The type used is unchanged, and the extreme care taken in
production is noticeable throughout. Anyone using paper (or
thin-layer) chromatography can save himself much time and
vexation by having Hais-Macek in his laboratory. Anyone
wanting a convenient introduction to further study of the
literature used in the handbook will find this in Volume 111,‘
with its ca. 8300 pertinent literature references, a 100-page
author index, and a 150-page subject index for 1957-1960.
Furthermore, the price for this excellently produced volume

is by no means excessive.
More than half of Part B is now devoted in the following
sections to the chromates, acidochromates, and chromium
double salts of m e t a l s . This indicates the importance of
these compounds in pure science and in industry, and shows
the wide range of combinations that can be formed by
chromium, for it occurs in various valence states, and forms
chromates(II1) and chromates(V1) with all metals, in some
cases even chromates(V). The discussion here covers not
only true chromates (and polychromates), but also acidochromates such as halogeno-, sulfato-, or oxalatochromates,
and metal double salts of chromium, such as chrome alums.
of the chapter is concerned with
The major part (about 65
the Cr compounds of the alkali metals, particularly the compounds NazCrO4, KzCr04, (NH4)2Cr04, Na2Cr207.
K2Cr207, (NH4)2Cr207, and KCr(S04)~.12H20. Of these,
sodium dichromate Na~Cr207,which is produced industrially
by alkali fusion of chrome iron ore, is important as the basis
of all other compounds of chromium(VI), and chrome alum
KCr(S04)2.12H20 is an important tanning agent. Mention
should also be made of lead, zinc, and barium chromates,
which are important chrome pigments. The latter have had
keen competition in recent years from coal-tar dyes, which
are non-toxic and extremely intensely colored, but chromates
are involved indirectly as oxidizing agents in the manufacture
of these coal-tar dyes.
T o summarize, these three chromium volumes represent an
impressive accomplishment by the Gmelin staff. The reference lists are complete u p to the end of 1949, a closing date
for literature perusal which was fixed in 1950, with the result
that the “Gmelin” is n o less than 15 years behind the presentday literature situation. An attempt has been made to alleviate
this apparent deficiency by reference to more recent literature

Die Nobelpreistrager der Chemie. Ein Kapitel Chemie-Geschicbte (Nobel Prize Winners in Chemistry. A Chapter
in Chemical History), by W.V. Bonin. Heinz Moos Verlag, Munchen 1963. 1st edit., 89pp., 69 portraits, half-linen,
D M 14.80 (about $ 3.75).
As the highest scientific award, the Nobel Prize marks the
great milestones of scientific discovery. Wulf von Bonin has
skilfully and vividly reviewed these milestones in chemistry
in the 45-page comprehensive text of the present book. It is
pleasing to note that any national appraisement of the Nobel
Prize was carefully avoided.
The text is followed by photographs of all the Nobel laureates
in chemistry to date beginning with Jacobus Henricus van’t
Hoff and ending with Guilio Natta and Karl Ziegler.
This series of photographs gives rise to thoughtful reflection,
although more care should have been devoted to the retouching (was it really necessary?). Altogether a volume to be
recommended to many chemists.
