Nutoctics appear in both systems. A linear dependence was found between
the logarithm of the solar SIX 4 fraction and the reciprocal value of
absolute temperature. The thermal effects calculated Cron the tangent of
this straight line lie near the melting hoate of SIX 4 and Al 216* The
systems, therefore, follow the Schrdder equation. The Raoult law holde for
both systess, Thiswas confirced by zeasuring the pressure of' saturated
vapor of pure SIX 40 Table 3 gives the boiling points of Al .16 between
148 and 054.5 torr, and of SIX 4 between 105*5 and 880.0 torr, determined
by means of a Sventoslavskty ebulltonster. The authors point to the pos-
sibility of calculating the phase equilibriun between liquid and vapor
from the data relative to the phase equilibrium crystal - liquid, and
vice versa, on the basis of the act1vttj coefficients, provided the system
does not deviate too tuch from an Ideal one. There are 2 ficures, 5 t&ble-,

TMt The kinetics of chlorination of higher oxides of tantalum, nioblum,
titanium and zirconium with liquid phoxitorus pentschlorldiO'I&s studied. The inves-
tigation was based on the assumptions 1) that chlorination In the condensated
phase causes only a slight change in the concentration of the chlorinating agent;
2) that the experimental arrangement of the Investlgatlon is easy, 3) that
chlori~atlcn products are obtained which can be used for Thai separation and
purification of x1rconium, tantaluin and n1oblum by the rectification method. The-
results obtained In the expertments, presqnted in the form of a relation between
the logarithm of oxide chlorination rate and the Inverse absolute temperature of
chlorination, obey in all cases the linear law. This proves that In the tempera-
ture lr~Urval studied (150-3000C) the chlorination processes take place in the
kinetic region, I.e., the rate of the process Is determined by the rate of the

chemical interaction. Based on the tangents of the Inclination angles of the
curves obtained the activation energies of the process were calculated. The values
obtained vary within the narrow limits of 25-33 kcal/wole and change little at
the transition from one oxide to the other. For zircontwu dioxide the activation
energy In 11.0 kcal/mole, but the reproducibliltr of the results Is low. The
chlorination rate of oxides in relation to the weight unit (in X/g'mln) depends
mainly on the temperature of their preliminary calcination. The principal cause
of the change In the oxide chlorination rate In this case is the change of their
specific surface. The character of the modification or the ocides attdied has
only a slight effect on the chlorinatIon rate. "Ihe chlorination rate of -r-MbA~
(calcinated at 8000C) differs from that of (X,-%O by only 1.5 times, whereas
for the same monoolinic modification of z1rConIu= d?oxide, but calcinated at 600

to be separated. The concept@ of "dynamically reversible" and "dynamically
Irreversible" elementary processes are Introduced. The naterial flow of

2) tonal flowl and 3) chromatographic process*@. The#* three processes are
typos of limiting cases. Kultistago column processes say consist of combi-

TEXT3 The authors carried out experiments for prepanng boron bro-
mide and iodide directly from the elements. As starting materials
pure bromine and iodine and samples of amorphous boron containing
87 - 99.5 % B were used. The halogenatione were periormed in ver-
tical quartz reactorep 3 - 5 cm in diameter. Boron was bricketed
with a sugar solution in methanol and the hologenation process was
carried out in a stream of argon at 640 - 10500C for 3 - 6 hours.
During halogenation fractions of the halodee were analyzed for free
Br. and 1. contents. For comparison purposes, one bromation reac-
tion was pcrforned In the reactor lying almost horizontally. All ex-

temperature being 850 - 9000C for both halogenation renctions; the
bromination yield was 94.5 - 99.5 % B Br 3* The iodination process
was quite similar to that of bromination, but with lower yields
(63.5 - 50 %). Purification of the crude halides, as well as of
technical B Cl was carried out by distillation In a rectifying
column of a platle-sieve type# with 25 real plates. The rectifica-
tion of technical B01 and that of the crude BBr3 faas easily car-
distillation BC13 was practically free
ried outt after the f
from 3101 and C0012, present in the Initial productp and BBr3 was
practiaLlty free from 5IBr4 and other volatile components; a pure
colorless product was obtained by a second distillation in presence
of copper filings. Furif:~catlon of the crude iodide was not so easy
owing to the high iodide content in the product. This was overco=e
by converting the fr e I to SnI # with metallic tin. The authors
were able$ by this m:thoi, to obtain from 3.2 kg of the lodination

TEXT: The possibiLities of separation of the above elements
by rectification are discussed and supported by experimeittal data
obtained on a laboratory apparatus. The ColLowing processes were
examined: separation and purification of.tantalum and niobium by
rectification of products of interaction of their pentachlorides
with phosphorus oxychloride; rectification of pert&chlorides br
tantalum and niobium; separation of zircconlum and hafnium by
rectification of products of interaction of their tetrachlorides
with phosphorus oxychloride; separation of t1rconium and hafnium
by extractive rectification of their tetrachlorides !-Abstractor's

of their tetrachlorides under pressure. The latter process is of
particular interest for industrial application but it presents
difficult problems. These could be solved by designing special
apparatus applying reliable temperaturg monitoring, salts as heat
carriers, voltage stabilization and automation of the process with
a view to continuous operation.
