ABSTRACT: Chromium plating of titanium and titanium alloys makev pDssible the
elimination of one of their main disadvantages, the tendency to seizing, thus widening their
field of appl-ication. However, chromium plating of TI endounters the, difficulty of poor
adhesion between the Cr azid the underlying surface, owing to tile pl-(!selice of Ti02 9-n. The
preliminary treatment of the Ti surface to remove this film Is therefore important and
has been attempted with a variety of reagents (HF, NaOll, KOH, HN03 + ITF, dichromato
+ IIF + CuS04, and acetic acid + IIF + alternating current). In tile present paper the
authors discuss the preliminary rtckling of the surface of Ti and VT-5 Ti alloy in some
detail, as well as working out the optimal conditions for chromium plating and the beat
reatment of the plated surface. Picklirg with 11F, llm,or H2SO4 was found to be

TEXT: The authors studied the conversion of n-heptane and cyclohexene
at atmospheric and Increased pressures in an autoclave In the presence
of sodium and KOH. For comparison, they give the results, of n-heptane
cracking in the presence of molten aluminum. n-Heptane vapor was con-
tinuously blown through a layer of molten metal or throtgh a packing of
KOH. At 7oo-wo0c, the vapor had a contact time of - 0.!, see. KOH was ap-
plied to active charcoal of the type KAR (KAD). The authors describe the
quality of the products used. Table I shows that the cre,oking of n-hep-
tans is inhibited by Na and KOH even at 8000C. The conversion is only
5-7% as compared to 34-57% without Na or KOH, Unchanged n-heptane was

obtained as a condensate from this cracking. No liquid products are
formed. The cracking gas largely differs from that of thermal cracking:
the_~jdrogen content amounts to 60-85% apart from a low content of Un-
saturated hydrocarbons. n-Heptane is radically changed -when it comes
into contact with aluminum. The conversion increases with rising tem-
perature and duration of the experiment: at 7000C - 65-3%, at 8000C
almost 100%. This is almost the double amount of experiments without
aluminum. Both gaseous and liquid products as well as condensation
products including carbides are formed. The authors astiume that at the
initial stage organo-aodium compounds are formed betweon 100 and 8000 C
under the separation of hydrogen. The cracking is inhiDited by the ad-
dition of H2 to the olefins in statu nasoandi (see Schame). Cyolohezene
was exposed to a temperature of 400 or 5000C and a pressure rising from
20 to 70 atm, after which the autoclave was gradually cooled. The ex-
periments were performed with and without sodiUm.'At 500OC9 cyclohexene
is completely resinified without Na (specific gravity of 0.9103), 2% of
gaseous products being formed. Slight changes occur in the presence of
Na: The iodine number decreases, and about 1.4% of ganes are formed.

TITLE: A New Method of Producing Propiotbiolactone~
PERIODICAL: Doklady Akademii nauk SSSR, 1,959, Vol 127, Nr 3, PP 564-566
(USSR)
ABSTRACT: Under the influence of ch3oro carbonic acid aster, P-propio-
thiolactone is developed by P-morcapturic.acide (Refs 1-3) in
the presence of triethylamine. It proved, however, that the
same thiolactones can be developed more easily by an influence
of H2S on the chlorides of P-halogen-carboxylic acids. The
extension of the reaction (I) on the chlorides of other 0-
halogen-carboxylic acids showed that the new method is of
universal validity for the production of P-propiothiolactone.
A careful investigation of the formation conditions of
a-propiothiolactone showed thatp according to the permanence
of the developing P-propiothiolactone, in some cases sodium
sulphide may be used instead of H 2S. In order to prevent
Card 1/2 a splitting of the developing thiolactone, the temperature

has to be kept lowt the theoretical amount of triethylamine
has to be used and too great an excess of H 2S has to be
prevented. Besides, the formation possibility of a,a-diphenyl-
P-propio-thiolactone by dehydration (angidratizataya) of
a,a-dipbenyl-p-mereapto-propionic acid was proved; for this
purpose one may use either chlorooarbonic eater or anhydride
of phosphoric acid. The dehydration of ~-oxy-acidi;, however,
takesplace under the development of unsaturated a,p carboxylic
acids. In case of a,a-bi-substituted 0-oxy--acide, no
P-propiolactone develops, but a reaction takes place contrary
to the aldol condensation (Refs 4,5) (soe scheme). 0,0-ditri-
fluorine-methyl-p-oxy-propionic acid is an exception, since
P,P-difluorine-methyl-p-propiolactone wits produced from it
recently, in the laboratory mentioned in the Association. There
are 6 references, 3 of which are Soviet.

TITLE: Addition of Alkyl-sulphenchlorides to Acrylic Acid Dorivatives
PERIODICAL: Doklady Akademii nauk SSSR, 1959, Vol 127, Nr 4, pp 799-802
(USSR)
ABSTRACT According to the polarity of the chlorides, referred to in the
title the addition mentioned there does not present any diffi-
culties resulting in the formation of u-alkyl-thio-~-chlorine-
substituted acids (see Scheme) (Ref 1). It was necessary to
check the data contained in reference 2, in which the author
asoribes the structure of the a-chloro-;-alkyl thioderivatives
of propionic acid to these addition products (see Scheme).
Further investigatione of the reaction mentioned in the title,
by the authors have again confirmed the opinions stated by them
before and have refuted the opinion expressed in reference 2,
i. e. the addition of the ethyl-sulphon-chloride to acrylic,
methacrylic, and dimethyl-acrylic acid, to the acrylonitrile,
as well as to the acid chloride and the ethyl ester of dimethyl
acrylic acid results in the formation of ~-chloro,x-alkyl
Card 0 thioderivatives of propionic acid (see Scheme). Duringthis

reaction the ethyl-sulphen chloride is easily added to eaters,
while it is more difficulttD add it to acids and nitriles,
and most difficult to add it to acid chlorides (Ref 1). From
the acid chlorides ofl-chloro-,L-alk thioderivatives of propionic
acid corresponding A-propiothiolactonee (Ref 5) were obtuined
by means of If23 (soo Schemo). With an order othor than that
illustrated by the scheme, the formation of the said lactones
would be impossible. Without cogent reasons Gundermann has
given his consont to the assertions of Brintzinger (11of 2)
acoording to which the ulkyl thiogroup aaeumes a 6--position
under the action of sulphen chloridea on acryl systems, whereas
the chlorine atom assumes an a-position. To give a definite
explanation of this problem the authors prepared a-chloro- -
ethyl thiopropionitrile (1) and L-ethyl thio-.'d-chloro propio-
nitrile (11) and compared their properties with one another
By adding ethyl mercaptan to a-chloro acrylonitrile (Ref 7)
the following reaction was brought about:

It was found that I and II showed the same boiling point,

and that alkyl-sulphen chlorides are added to acryl systems
according to the above polarization thus forming L-alkyl thio-

TITLE: Electrodeposition of Palladium (Elektroliticheskoye osazhdenlye
palladiya)
PERIODICAL: Tr. Leningr. politekhn. in-ta, 1957, Nr 188, pp 225-231
ABSTRACT: An investigation is made of the processes involved in pallad-
ium plating in phosphorus electrolyte (E) in a stationary bath
and in a bell-type bath, and also in neutral E with soluble anodes.
Palladium plating in quiet E was run under the following condi-
tions: Solution of 2.5-10 g PdCl?/Iiter, 2.5 8 benzoic acid/liter,
20 g (NH4)2HP04 per liter 100 NaZHP04/liter, pH6.5-7.0.
temperature 500C, DK= 0. ; amp~cm?, potential I or 2 v. Pt. Pd,
and carbon anodes were tried. Carbon electrodes are recom-
mended for large-scale industrial palladium plating. The Pd was
deposited directly on parts made of polished phosphorus bronze.
It is shown that 1.5-2 micron bright Pd platings can be produced
in phosphate E containing from 5 to 10 g PdC12 per liter, the
temperature of the solution being 500C. The dependence of cur-
Ca rd 112 rent efficiency in Pd deposition upon the bath content of PdCl ~

(1-10 g/liter) and upon current density (0.05-0.2 amf/dm2) is investigated.
I
The highest current efficiency is that at 10 g PdCIZ/liter and DK- 0.1 anrip/dtnZ.
The polarization curve of the Pd deposition process can be divided into 3 seg-
ments. In the first segment the process occurring does not involve liberation
of Pd. The second segment is that in which the Pd?++ 2e - Pd reaction oc -
curs. Liberation of H2 in addition to Pd is observed during the Teriod repre-
sented by the third segment. The maximum current for the Pd2. + Ze - Pd re-
action is that occurring at DK =0.15 arrip/dm?-. It is shown that a reduction in
the PdC12 content of the bath to less than 2.5 g/liter results in a dark deposit
and diminishes the current efficiency. A 4-liter bell has been designed to
mechanize the palladium plating of small parts. Under the same conditions as
those used in a quiet bath, and with a lO_dm2 area of part surface to be plated.
bright Pd deposits of 1.5-2 micron thickness were obtained. 'rhe porosity of
the Pd deposit is determined by immersion in a 15% HN03 solution for 10- 30
min. The pores are marked by the points at which bubbles attach to the Sur-
face. It is found that the number of pores goes as high as ?_5 per cm2 in a coat-
ing 0.1 micron thick, while no pores are found in a 3.5-micron coating. It was
found that it is possible to coat with palladium in neutral E with soluble Pd
anodes, provided that an area Of insoluble carbon anodes equal to 1/3 the area
of the Pd anodes is had in parallel.

TEXT: It was established that a zmall amount of Pb substantially increases
the afterglow of Bi-activated calcium sulfide (CaS) and strontium sulfide (SrS).
The conditions for producing this luminophor were determined and its character-
istic properties were measured. The afterglow of this luminophor is several
times greater than that of the substances possessing protracted afterglow that
have been known up to the present.

Analytical Chemistry of Rare Elements SOV/4759
for the analysis of the rare and dispersed eiements. Most of
the methods described here have been checked and verified in
Czechoslovak research laboratoriesj the rest have been borrowed
from Czechoslovak and foreign literature on analytical chemistry.
The book consists of a general and a special part. The general
part briefly describes systematic procedure in the analysis of
the rare and dispersed elements, reviews present-day methods of
chemical analysis, including those for the qualitative and
quantitative analysis of the rare and dispersed elements in
mineral stock and raw materials, and li, several products of
metallurgical processes. The specia'4 part contains a descrip-
tion of the most important natural compounds of each of the
elements studied, and deals in detail with concentration methods
and basic methods of qualitative and quantitative determinations.
The author thanks Doctor V. Sykora. The editor of the Russian
edition of the book thanks Yu. N. Knipovich and M. P. Belopoll-
skiy. There are 449 references,most of which are Czech, Englishj
and Geman. The 38 Soviet references given encompass Soviet
literature in the field to 1953. The balance of the references
includes non-Soviet literature to 1955.

arsenic trichloride, Germanium dioxide is isolated from the
chloride by hydrolysis with superheated steam or by treatment
with ammonia and the crude dioxide will then contain as
impurities: chloride, ammonia, arsenic and water. The authors
have developed a rapid method for the analysis of the different
components of the germanium dioxide process, which they claim is
very suitable for works control. Analysis of germanium by
volumetric methods is based on the change of pH on the addition
of pyrocatechol to a neutralised solution of germanium dioxide.
Arsenic does not interfere in the reaction. Details of
titration are: 0.1-0.2 g crude germanium dioxide are dissolved

Of the gravimetric methods for the analysis of germanium, the
authors have found the formation of salts from germanomolybdic
acid the most promising. However, only the salts with
8-hydroxyquinoline gave reproducible results. The method is not
recommended for quantities exceeding 3.5 & germanium. A
photometric metbod was also studied and plienylfluorone, which
gives a very sensitive red colouration, was confirmed as suitable
reagent. The method is recommended for the analysis of flue
dusts. Analyses for chlorine, ammonia and arsenic follow
conventional lines. They were, however, conducted in order to

Analysis of Technical Germanium Dioxide
establish whether germanium dioxide interfered with the
analytical method. It was found that this was not the case.
The three constituents were determined in a single sample of the
solution as follows: Ammonia - Kjeldahl method; Chlorine -
titration with silver nitrate in presence of sodium nitroprusside;
Arsenic - iodometric titration (starch). Acknowledgements are
expressed to Engineer Jan Stanek for supplying the required pure
materials.

Abstract: The earlier described photometric method (Tomicek
0., Jerman L., Chem. listy, 1952, 46, 144) was
modified for the determination of Ta, and an ana-
logous method for Nb determination was developed.
These methods are based on the formation of colored

surement of the light absorption by the yel-low Ta
chelate with I is carried out at about 400 MA4,(viojet

is carried out at 470 m," (blue light filter). The
cOMPOsition of both the chelates is expressed by the
ratio Ta (Nb) : II = 1 : I - Vie chelates are pro-

in respect to Ta and 11. The Presence of II is es-
Pecially advantageous due to the fact that II sequesters
