TOPIC TAGS: lanthanum, prasoodymium, noodym!Lum, gadolinium, carboxylic acid,

SUB CODE. 32, 07
ABSTRACT: Tho nuthors studied some peculiarities in the reaction of diluents
with aliphatic synthetic acids of the C7 - CO fraction in the extraction of
lanthnnum, praseodymium, neodymium and gndoliniun. The role of the diluents
depends essentially on the proton affinity, as well as the ability to forn
addition compounds with the acid molecules -through hydrogen bonds of varying
strcn,-,tli and polarity. Carboxylic acids and alcohols posses donor-acceptor
properties with respect to hydrogen. Cxtra,-tion is considerably less affacted
by diluents which aro only proton acceptors In an acid-base reaction. Nonpolar
dilynts have the least effect. The diluents studied are lisM In the

water was drawn off from the neutralized'product at 95 - 1300C and with a
residual pressure of 150 - 200 mm Hg. The filter press proved inadequate
to liberate the additives from mechanical impurities, the content of which
in the neutralized product reaches 1-7 - 2.0 %. Satisfactory results
were obtained by using for this purpose a TE-800 (TV-800) centrifuge.
However, this part of the process needs further develo ment. The physico-

ABSTRACT: The affect of the pH on the cor, sion x-asistance and stationary electrode

hydroxide) on the surface of the yttrimo The dissolving of yttri= pia-etically ceased
to exist after 50-75 hours of the experiment* The rate of corrosion of yttri= de- I'
creased with increased pH., especially in the aoid region (pH 2,- 4), The corrosion rfia.
was somewhat lower in nitrate than in chloride solution. The metal was in the passiVb '
state at a lower pH (10-5) in the nitrate solution than in the presence of Cl- (pH 13)4

alkalies. Therefore# the presence in solution of NO and especially of Cl- has no
effect on the resistance of yttrium to corrosion* 2ermodynamically, yttrium should be
a very active metal electrochemically. The standard potential of reaction Y = Y34,+3a
is - 2.37 v& But even the most negative potenti0sof yttrium In the solutions studIcA
were I v more positive. This suggested the presence of a protective film on the yttriua
surface even in the active state of yttAum. The curve of stationary potential - PH
for yttrium in chloride solution consisted of thrae parts. The stationary potentials
at a potential below 3 and above 10 decreased with decrease or increase of the PH.,
respectively* The potential slightly increased with a decreased PH in the interval of
PH 10-3, According to Go Ve Akimov and 1. L. Rozwifeld (Issledovaniya v oblasti elek-
trokbimicheskogo i korrosionnogo povedeniya metalov i splavovp Oborongizp M., 1950)j
this can be explained most satisfactorily by the presence of potentials of the film-
pore type on the metal surface, A complete passivation of yttrium in chloride solution
occurred at PH 13* The inflection on the cury t PH 3 indicated a change in surfacetl

ABSTRACT: The corrosion kinetio3 and the electrochemical properties of
yttrium in 2% and 18% HF were studied at 250 and 900. Reduction in
corrosion rate with time was proved to be due to the formation of a
protective film of YF3*--Under the test conditions -- 250 hours at 250
and 24-50 hours at 90 the film remained intact$ but on prolonged
contact in HF the film brooks dorm and chips off. Deep pits and film
crumbling were noted in 2$ hours in vapor pbase teats. Removal of
oxygen from the system bad no effect on the corrosion rate. The

where K 0 and T 0 are limiting magnitudes of coefficients

The equations of free oscillations are given for these
four cases on the basis of previously published papers.

is shown on Fig. 3. The phase representation of the
