ABSTRAM Tungsten oxychlorides are only occasionally described in
publications. However, as tungsten forms a considerable number
of oxides and chlorides, a corresponding number of oxychlorides
may be expected. The equipment used in the investigation is
schematically drawn in figure 1. One of the thermograms drawn
by means of two U-21 reflecting galvanoaeters is given in
figure 2 as an example. A scheme of the electric furnace is
shown in figure 3. Figure 4 represents the melting-point diagram
of the system WC1 6 - WO,. From this it is evident that two
oxychlorides are formed in the system WOC1 4 and WO2C1 2' From the
melting-point diagram of the system WICI 6 - WO 2 (Fig 5) three

A13STRACT: There are only a few data available in publications on the
bromine compounds of tungsten presently known (WBr 61 WBr,,
YBr 2# WOBr 4' W02 Br 2). For this reason the authors report on
tensimetric and thermographic determinations carried out on
WBr 5* W(CO16 and Br 2 were used as initial products, which re-
act under formation of hexabromide which was decomposed in

made of heat-reeistant glass of the P-15 type. The temperature
was measured by means of the PPTV-1 potentiometer. Table 1
gives the values obtained for the vapor pressure of WBr 5 betseen
Cai'd 112 170.4 and 384.40C and 1 - 655 torr. In figure I the curve

log P f(1000) is shown. Between 2300 and the melting
saturated T K
point 2950C the values are below the calculated curve owing
to impurities. The computed values for the vaporization and
sublimation enthalpy and -entropy are in good agreement with
the values obtained by L. Brewer (Ref 1), whereas the resultant
melting- and boiling points deviate from the data available
in publications. According to table 3 the anelynis of WBr 5
gives a bromine content somewhat higher than that corresponding
with the formula which is due to bromine adsorption. The values
computed at 676.20K and 742.20K for the molecular weight of
WBr5 are likewise above the theoretical values The presence of
polymerized molecules in assumed. The solidification tempera-
ture obtained by tensimetry deviates a little from the value-
determined thermometrically (Table 5). There are 1 figure,
5 tables, and 6 references, 2 of which are Soviet.

A,B~THACT: For the analysis of gas- and vapor mixtures it is possible to
use the opectrum of this irixture in the visible-, in the
ultraviolet-, ur in the infrared range; whereas in the ultra-
violet ranee the cuantum enor(,ies are already so high that
un-called for pho-tochemic-al r,~,-vstians occur, the strong
influence exercised by temperature in the infrared range is a
disturbin6 factor, For the investigation of a complex system
in equilibrilim, a spectrosccpic. method is. in any case,
insufficient, becwase is necessary, besides the partial
component pressure3- to know alac the total pressure in the
system. For theii determ~ivrition it J.E; possible to employ W
statistiral method, b!:~'. the menbrane method (with zero
manometer) was fcund to be especially useful. It was found

amount of absorption has hithert,~, not been quantitatively
investigated. Such an empirical method was the aim to be
fulfilled by the authorv. An inlrestAlgation of the temperature-

iodine vapors resulted in the formula Ky - xx T, where x,
is a quartity which is independent of temperature. For its
verification the system N 2 04 No 2 - 110 - 0 2 was investigated

TITLE: Membrane Zero Pressure Gauge for the Measurement of Vapor

nullmanometr dlya izmereniya davleniya parov v shirokom

PERIODICAL2 Zavodskaya Laboratoriya, 1959, Vol 25, Nr 6, pp 750-751 (USSR)
ABSTRACT: Several years ago a production technique was worked out of
membranes for zero pressure gauges without the shortcomings
of the pressure gauges according to reference 2 (Ref 1)~ As
the membrane chamber is also in the present case not quite
small enough, a device with smaller dimensions and a flat
membrane was constructed. The pressure gavge may be made of
molybdenum- or pyrex glass as well as of quartz (figure 1,
scheme of the pressure gauge). The glass membrane is made
from a glass ball which is blown and then flattened (Fig 2),
A rodlet is melted on to the surface the shift of which in
connection with a motion of the membrane indicates a change
in pressure on an opposed needle, The sensitivity of
measurements depends on the quality of the membrane, the
Card 112 thickness of the rollet and the deviation of the top of the

the device was confirmed in determining the vapor pressureg
of sulfur, mercury, iodine, nitrogen oxides (Ref 4) etc.

TITLE: Method of Determining the Pressure of the Saturated Vapor
of Difficultly Volatile Substances
PERIODICAL: Zavodskaya laboratoriya, 1959, Vol 25, lir 9, pP 1097-1099 (USSR)
ABSTRACT: A method was developed by which the sample is vaporized in
an inert gas in a cloW vessel, the inert gas acting as
elastic medium which transfers the vapor pressure to a pres-
sure gauge outside the high-temperature range. From the scherne
of the gauge (Fig 2) it may be seen that the substance to be
investigated evaporates in a cylindrical quartz vessel which
is housed in a furnace and is connected to a diaphragm zero-
pressure gauge by means of a tube. The latter is contained
in a thermostat and transmits the pressure to the pressure
gauge which permits measurements with an accuracy of * 0.5 torr.
From the measurement results obtained on the apparatu; describ-
ed the preaoure of the saturated vapor of KCI was computed,
and a curve of the dependenoe of the vapor preaeure on tom-
perature was plotted (Fig 3). Comparison with the correspond-
ing values in Stall's table shows good dgreement of the data.

tion of MoCl 3 and WC1 4' and 11oOCl 4). Two calorimetric methods were applied:
1) Comparison of the heat of solution of the investigated substance to the
heat of solution of a substance whose heat of formation is known (Table 1).
2) Combustion in oxygen (Table 2), Furthermore, the vaporization, depoly
merization, dissociation, and disproportionation processes taking pla,-.e in
a state of equilibrium, were spec tropho tome tr ioally and tensimetrically
investigated (Tables 3, 4). The enthalpies of formation, and partly also
the standard entropies of formation were calculated from the experimental
data. In Tables 5 (Mo compounds) and 6 (W compounle) they are compared
with the data given in Ref. 2 which were adopted almost unchanged by the
US National Bureau of Standards (Ref, 9), The values determined by the
authors are 1.4 1.7 times as high. Therefore, the dependence of the
free energy of formation of temperature is different altogether 6 This is 0

PERIODICALs Zhurnal neogranicheskoy khimii, v. 6, no. 8, 1961, '951-'952
TEXTs The authors used the "boiling point" method which has the advantages
of the method by L. G. Berg (Ref. 21 IZV, Sektory fiz.- k.him. analiza, 22,
140 (1953)). This method makes it possible to determine the moment wheT
the vaDor pressure of the substances equals the pressure outside the reac-
tion vessel. in the present case, this moment was determined from the
temperature drop of the substances, which occurred with their increasing
evaporation near boiling point. The apparatus required is shown in Fig.l.
When experimenting with hygroscopic and easily oxidizable subotancee, the
reaction vessel is connected to a vacuum apparatis and filled with pure
and dry nitrogen. The current from the differential thermocouple is
measured by a mirror galvanometer of 10-9 a/mm-m sensitivity. Gradual
pressure drop was effected in the system at constant temperature, and the

ABSTRACT: The ~Apor pressure of the PrCls-Pr, NdCls-Nd, and LaC13 - La
systems and the solubility of the rare' earths in the chlorides of these systems
were determined in the 1180-13500C range. The vapor-pressure samples

dissolution of atomic La occurs and that ions of Pr(10 and Nd(ll) form in the melt.
In all three systems the tricfiloride was the only compound to vaporize. Instability
of the dichlorides in the vapor phase is probably associatdd with their. high heat of.
vaporization. -The positive deviation from Raoult's law observed In the PrCl -Pr
system may be attributed to the presence of some atomic Pr. The experimental
heat of vaporization in the single-phas'e region was close to that of the pure
chlorides (LaC13, PrCl... and MCI.), indicating that the overall heat effect of
processes occurring during the dissolution of the trichlorides in the melt was
close to zero. The difference between the heat of v6porization of the pure
trichlorides and that of NdC15 and PrC15 in the phas e- separation region is
governed by the heat of reaction of the disproportionation of the dichlorides. The
latter was found to be 38 � 10 kcal for NdC12 at an average temperature of 1250*C,
and 24 � 10 kcal for PrC12 at an average temperature of 12306C. For thermo-
dynamic calculations from the data obtained on the disproportionation of the
dichlorides, more precise information concerning the nature of ions formed in
the melt on dissolution of the metals, as well as experimental data on

ABSTRACT: This work resulted from ;he lack of data on the stabilizink
action of alkali halides on the diialides of rare earths. The
formation of solid phase compounds was observed and complexes were
traced in the liquid and gaseous phases of trichloride3. Since there
also is no literary data on the effect of KC1 on rare earth dichlor-
~ides, fusibility tests of Sm and Ybdi- and trichlorides with KC1
were made and fusibility diagrams plotted. It was-found that thd
solid state compound KCl~2SmCl2 decomposes during melting, while
KCl-YbCl2 malts without decomposition. There is a sindlarity of

ABSTRACT: High purity anhydrous lanthanuAnd erbiumqhlorides (LaC13, ErClD i
were prepared from La2(C204)3 anCErJC204) -4-5 H20, respt~ctively. In each case
a 3't.o 4 gram sample of oxalate was placed In a quartz vessel and a mixture of
CC14 and chlorine was blown over the sample for 30-40 minutes at 2000C in order 1
to remove air and moisture. Then the temperature was raised to 4000 to 4500C and
the oxalate sample was subjected to the CC14-C12 mixtures (chlorine saturated withi
i- carbon tetrachloride at room temp.) for 2.5 to 3 hours. The flow rate of the
I xture was about 3 to 4 Mr. Finally the temperature was raised for a
CC14+CI2 Mi
short time to 6000C. The resulting product was found analytically to be close to
100% LaC13 Or ErC13- Spectral analysis showed the total impurity (Fe, Al, Ca, Mg,

also to other rare earth elements since all the oxalates of rare elements decom-
pose at a temperature close to 4000C. Orig. art. has: I table, I figure, and 2
