SOURCE: Hutnik, no. 8, 1965, 344-347 16
TOPIC TAGS: pickling, automatic regulation, metallurgic nachiner7
jk3S'LLZACT:_ The performance of the pickling bath is influenced by
two components in the bath: free acid and the salts of the
iretals disadved in the bath. The authors describe an automatic
regulator of the composition of the bath produced in Czechoslo-
valcia, and marketed under the trade name ItMela". Details of the
construetion of the apparatus are described. Temperature, con-
ductivity, and density of the solution are recorded; the evalua-
tion is made automatically from the inputs fed to the analyzer
in the form of electrical impulses, The apparatus has three re-
gions or operation: 170-220 k/1 H.,,304 and 0 - 60 g/1 Fe; 250 -
300 g/1 acid, and 0 - 60 g/l Fe; kad 40 - 100 g/1 of acid and
0 - 40.g/l/of Cu. There are two ways in which the bath can be
controlled: either the acid is added contim7ously, and the bath
is periodically regenerated, or a slip stream of the bath Is re-

TITLE: On the Production of U 308 Crystals and the Investigation of 'rheir
Structure (Polucheniye kristallov U izucheniye ikh struktury~
308
PERIODICAL: Atomnaya euergiya, 1958, Vol. 5, Nr 2, pp. 181-183 (USSR)
ABSTRACT: The influence exercised by uranium initial materials and the con-
ditions of their precipitation, temperature and time of thermal
treatment upon the amount and the state of U 308 were inventigated.
Uranyl nitrate, am nium uranate and uranium peroxide served as
initial material for the representation of U 308. The thermal treat-
ment of uranium salts ( the weighed portion amounted to 5 - 200 g)
was carried out at 1 11000 in the course of 5 hours, 48 hoursp and
7 days.
For the accurate X-ray determination of the crystals it was
necessary that the samples consisted of crystals of the same order
of magnitude. A sedimentation in water took place; 5 g of each
reparation was sedimented in 5 fractions and various times
Card 1/2 r1O see, 2 min, 30 min and 24 h). X-ray pictures were made by the

method of inverse pictures. The distance between film and sample
amounted to 30 mm; time of exposure: I hour. No crystals in-
vestigated have a hexagonal structure, as is assumed by some
authors (Ref 9) , but are of a rhombic structure. Some of these
crystals show weak, layer-like lines which are indicative of a
threefold periodicity with the distance 3a. However, also weak
lines were found which indicate a two-fold periodicity with the
distance 2o. There are 12 figures, 3 tables, and 10 references,
2 of which are Soviet.

TITLE: Laboratory Purification of E
PERIODICALs Chemic4 Pru'3mysi, 1960, Vol 10, Nr 5, pp 251-252
ABSTRACT: L laboratory method for the purification of technical
ethylene is described. The purified compound was
analysed by chromatographic method. Its impurities were
less than 0.01% and did not show an Inhibition period in
free radicle pelymerisations. A diagram of the assembly
of equipment is given. The method of purification is as
follows. Technical ethylene is passed through an aqueous
solution of potassium hydroxide, followed by passage
through a purifying column containing a solution of
cuprous chloride, ammonium chloride and copper shavings.
It is then led through a column of concentrated sulphuric
acid, anchored on silica gel. The final passage is through
columns of silica gel with carbon dioxide as carrier and
flow determining factor. The final purification was
Card carried out by gas chromatography using again carbon
1/2 dioxide as carrier. It is claimed that completely
reproducible results were obtained. The course of the

TITLE: Anionic polymerization of formaldehyde. II
PE-KODICAL: Vysokomolekulyarnyye soyedineniya, v. 4, no- 5, 1962, 769-775
TEXT: In continuation of a previous paper (Vysokomolek. soyed., 3, 1421,
1961), the authors studied the poleerization of saturated formaldehyde
solutions in aiethyl ether at -59-3 C. The molecular weight of the
polymers was determined from viscosity measurements in the solvent mixture
tetrachloro ethane - phenol (3 : 1) at 900C. The time dependence of the
formaldehyde concentration shows that the order of reaction is higher as
referred to the monomer and increases during the reaction. Therefore,
only the initial rates in the first 2 min, reaction of second order were
taken into consideration. The molecular weight changes very little up to
a 40-0%a conversion, and then decreases. Tetrabutyl ammonium laurate (TB4~
dibutyl amine (DBA), and tributyl amine (TBA) were used to study the
effect of catalysts. With TBAL, the reaction was of the order of 0.8 as
referred to the catalyst (the catalytic effect increased after TBAL had

beer, stored for some time), and with DBA and TBA it was of the order of 1.
Only a small portion of the catalyst is required for initiation. The ratio
between the catalytic efficiencies (reaction rate/catalyst coricentration)
of TBAL, LBA, and DBA was 4-5 ; 3-5 : 1.0. The molecular weight is
independent of the type and concentration of catalyst. The dependence of
the reaction rate and molecular weight on the concentration of the monomer
was studied in the presence of DBA and TBAL. In the first case, the order
of reaction was found to be 1.7 and 2.6, depending on the impurity
concentration, and in the second, it was 2.4. The molecular weight is
directly proportional to the monomer concentration. The relative chain-
transfer constant Cc was determined according to C. H. Bamford et al.
M
(see below) and found to be leas than 0.05 9/dl. On the other hand, the
numerical polymerization coefficient P is proportional to [Fdl/[HXI
L
(Fd - formaldehyde, HX - acid impurityl, and the molecular wei'ght is
inversely proportional to the concentration of impurities. The ratio
between the concentrations of impurities in formaldehyde and ether was
found to be 13. There are 8 figures and 2 tables. The most important

TEXT: The effect of typical impurities of formaldehyde and diethyl ether
used as a solvent on the polymerization rate and molecular weight of the
polymer was studied in anionic polymerization of formaldehyde. Dibutyl
amine or tetrabutyl ammonium laurate were used as catalyets. These
impurities fall into four classes: (1) impurities which react neither
with the catalyst nor with the active center of polymerization and are
therefore ineffective (e.g., CO and 02); (2) impurities which reduce the
molecular weight, but hardly affect the polymerization rate (8.9', H201
CH3OH). They react with formaldehyde to form anions of almost the same
basicity as that of the growing anions. Their effect does not depend on
the type of catalyst used; (3) impurities which reduce both the molecular
weight and the polymerization rate (e.g.' HCOOH, CH 3COOH, and CO 2) . Their

effect does not depend on the type of catalyst used, and form less basic
anions which stop growing; (4) impurities which reduce, not the molecula.-
weight, but only the polymerization rate (e.g.9 HC1). An equivalent amount
of catalyst is passivated. The following relations were found experimen-
tally: H 20 : CH3OH : CO2 . CH3COOH : HCOOH - 1 : 3.1 : 21-5 21.9 : 23.8
for the effect on the molecular weight, and CH3COOH : HCOOH CO2
- 1 : 6.2 : 13.8 for the effect on the polymerization rateo The activation
energy of polymerization in the presence of tetrabutyl ammonium -laurate
was measured at -58-5 - -34.90C and found to be 4-1 kcal/mole. The
apparent activation energy of the increase in molecular weight is
-2.7 kcal/mole. There are 9 figures.
