ABSTRACT: A device for saving Au from industrial caustic solutions by
adsorption on anionite resins of low swelling capacity, porous
structure, and fundamental properties favorable both to ion
exchange and to adsorption, has been developed and tested suc-
cessfully under industrial conditions. Dissociation of such
anionites in aqueous solutions with formation of cations of low
mobility facilitates coagulation o-f-Au and ensures speed and
completeness in precipitation thereof on the adsorbent. The
resin is separated from the soluti4by means of a Nutsche
filter. Joint ion exchange and reduction by hydroquinone was
Card 1/2 applied to Ag and Au solutions. This significantly increased

the absorptive capacity of "H-0" anionite and made it possible to extract up,
to 112.856 Ag and 114.6% Au relative to the weight of dry resin (and this did
not even exhaust its absorptive capacity). It proved possible to extract up to
721o of the Au in sea water when 50 g resin was used per 500 liter of solution,
but the resin was contaminated by Fe salts. The "H-0" resin is suited to re-
covery of Au frorn highly- contar-ninatcd, exhausted caustic electrolytes, but
regeneration of the resin by the usual means is not possible. "H-011 resin
permitted the extraction of 80-901o Au from a solution of Au resinate in turp-
entine containing 3.5 g Au per liter.

ABSTRACT: The shape and the physical properties of the particles of the
synthetic resinslused as ionites are of great importance for
practical application. Most of the ion exchanging resins have
with
hitherto been produced as grains of irregular shape ('
sharp edges). They are obtained by crushing the solidified
polymer. The 10 - 15% of dustlike waste forming in this
connection oannot (with one minor exceptiong Ref 1) be
properly used in industry. The costs for their ap lication
as fertilizers in agriculture are too high (Ref 23. The
Polycondensation mentioned in the title is based on the
Card 1/3 solidification of the polymers in liquid state. Thus, crushing

On Granular Polycondensation and on Polymerization BOV/156-58-2-42/48

is not necessary and the waste decreases to 0,3 - 00~-
According to temperaturey intensity of mixing and the
properties of the surface-active substances in the solution,
ionites can be obtained as spheres of different size. This
shape of ionites has a number of advantages as compared to
that of the irregular grains, The problem of the methods of
production of such spherical ionites has not been sufficiently
elucidated in publications (Ref'3). The authors made it their
object to produce several already known and several new
anionites of spherical shape. Final solidification was
obtained by an additional heating of the polymer in liquid
state in different media: oilep benzene, glycerinc, saturated
NaCl- and CaCl - solutions and others. The test results were
2
Obtained by using transformer oil as solidifying medium. On
contacting the oil the polymer drops are covered by an oil
film which prevents the coagulation of individual drops and
thus the formation of greater aggregations. At a temperature

ABSTRACT: The authors investigated two forms of the chemical reaction
in the polymeres mentioned in the title, which were used in
granulated form (diameter 0.25-2.0 mm): 1) Nitriding wfth
following reduction of the nitrogen group, and 2) Chloro-
methylating with following substitution of the chlorine atoms

nitrogen contelit avergged 12-14 % (Table 1). A high content
of divinylbenzene aggravated the nitriding and resulted in
a lower nitrogen content. The nitrided granulate was of yellow

interlacing of the copolymeres, the force of the reaction
decreases (Table 2). The static anion-interohangeabil'ty of
the best resin test-pieces amounted to 6 25 mg-equiv/g for
0-5-normal hydrochloric acid and 7.75 mg:equiv/g for 0-5-nonmi
sulphuric acid. During the second series of tests, copoly-
meres with a divinylbenzene content of 2, 4, 6, 8, and 10 %
were treated with chloromethylether (Table 3) and their
chlorine content was determined. The copolymeres with a
Cl-content of 18-19 % were substituted with trimethylamine.
The rest-content of chlorine amounted to 7-10 %, the nitrogen
content to 2-2-5 %- When treated with pyridine instead of
trimethylamine, the copolymeres contained 9 % chlorine and
also 2-2.5 % N. The static anion-interchangeability was
2-3 mg-equiv/g for 0.1-normal hydrochloric acid. There are

amine nitrogen insignificant. The degree of deioniza-

TEXT: The authors aimed at producing a cation exchanger containing SH-
and =S groups and which, besides being used for analytical purposes, may
also serve for the separation of metals, whose sulfides are difficultly
soluble in water. For th.& synthesis of such an exchanger--resin, the authors
used two methods. 1) The'ICArr(SDT) resin was obtained by the treatment of
a chloromethylated copo-rYi-erof styreneland 2-4% divinyl benzene with
thiourea. The SDT resin contained 11.3 -: 15.48% sulfur, and was hydrolyzed
by means of 5% NaOH. The yield was 70--65%, referred to the initial chloro-
methylated copolymer. The sorption properties of this resin are only little
influenced by the pH. The dynamic exchange capacity, measured by means
of 0.1 N AgN`0,, amounted to 2.7 - 2.8 mg-eqtdy'19. The regeneration was carried

out by reducing the silver with NaHSO 3 or Na2so 3" When NaHSO3 ?ias used,
no decrease of the absorption capacity occurred. In eight cycles of sorp-
tion and regeneration, 238.7% Ag, calculated per weight of the resin, and/
or 22.1% mg-eqiAv/g referred to metal were adsorbed on the cation exchanger.
2) The'CHrjSNK) resin was obtained from a polymer containing amino styrene
and 2%=iATinyl benzene by means of diazotizing with an excess of HNO 2 at
50C and treating the diazo compound with potassium ethylxanthogenate, The
sulfur content of the resin was 5,16 - 6.10%. The dynamic exchange capaci-
ty determined by means of AgNO 3 was 2.13 mg-equiv/g. Also in the case of
this resin, NaHSO proved tobemore suited for regeneration. because the
capacity did not aecrease to such an extent as when using the Na 2so The

64% moisture. An amount of 59,189 liters of water was filtered through the
column at an average rate of 40 1/hour. The qualitative and quantitative deter-
mination of various elements in the resin was carried out by radiometric
x-radiation, luminescent and polarographical analyses. The amount of uranium

scopical analysis of ash residue after burning the 0-H resin was used to estab-
lish the presence of small amounts of silver, strontium, bismuth, zinc, copper,.
manganese, iron, aluminum, silicon, calcium, magnesium, and sodium. The silver
content in the absorbent was determined by cupellation of the ash residue after
barning 200 g 0-H resin. An amount of 2.5 mg pure silver was then separated out
which is 5.75 , 10-7 g per one liter of water. There are 4 tables and 13

TEXT: The authors studied the chloromethylation of vinyl toluene - ethylene
glycol dimethacrylate and vinyl.toluene - diethylene glycol dimethacrylate
in granular fo�m (grain size 0.5-1.0 mm) by means of monochloro methyl
ether in the presence of SnCl4 and ZnC12 as catalysts. The content of
ethylene glycol dimethacrylate and diethylene glycol dimethacrylate in the
polymer was 2, 6, or 10~4. Reaction time and catalyst concentration wie~re
varied in the experiments between 0.05 and 0.75 moles SnCI 4' or 0.1 and
0-75 moles ZnCl2 per base molecule of the copolymer. The following

optimum ::eaction conditions were found: reaction time 2-4 hr, dependirig
on the co-,itent of crosslinking agent; 6-1051 crosslinking agent in the
CoPol.ymer; 0.3 moles ZnCl2 per base molecule of copolymer in the '
reaction --aixture.' Copolymers containing 28.8~6 chlorine were obtained,
corresponlimg to 158 chljoromethyl groups per 100 ben7ene nuclei. Reaction
times-over 4 hr reduce an existing; chlorine content (formation of methylene
bridges ivith separation of H01). Catalyst contents over 0.3 moles per
base molecule of 7poly-mer cause a higher C1 content in the final product,
but reduce its mechanical strength. There are 4 figures. The most

T--.;'XT: Thi successful application of redox processes for the con-
centration and desorption of noble metals oil granular ionites in an
electric field prompted the authors to use these processes in -the
case of some lanthanides endowed with variable valency. Having cho-
sen Yb and Bu as the elements to be tested, the authors intended
first-to check the possibility of desorption in the electric field
of tervalent cations adsorbed on ionites, and then to try to re-
dUce them to divalent ions and utilize the low solubility of sul-
phates for the purpose of concentration. Conditions have been stu-
died of extracting and concentrating Bu and Yb from dilute solu-
tions by means of'the cationite KJ-61,(KU-2), and a method has been

desorption in the electrical field with the use of a Hg catChlode
