ABSTRACT: The thermioaynamic 6haraoteristics of tungatates an& molybdAtea of
bivalent metals have becu investigated at the laboratory of the
authors since 1944* The method of circulation applied so far was
not applicable here as zinc evaporates and is carried away from
the reaction zone. The method devised by J.A.Kitchoner and
So Ignatovioz, (Ref lop rig 1) was therefore employed, ye tnot the
quantity of the vollatile product but the hydrogen content of the
gas mixture in equilibrium was determinedg i.e. by measuring the
electromotive force,between two hydrogen electrodes, one.being
saturatedwith pure hydrogen and the other with a mixture of
hydrogen and argon. In order to check the precision of the
apparatusq.the.authors measured the temperature dependence of the

ABSTRACT: The determinations mentioned in the.title were carried, out in
the molar calorimeter within the temperature ranges of 683,2-
293,20K to 1125,2-293,20K.-The scheme, the method employed as.
well as otherdetails were already described (Ref 1). Data on
the technique of preparation-and analysis are given. The results
obtained are given in a table. In the table the mean values of
..~the specific heat are given for each temperature range, an so
are the comparative values of parallel experiments. Equations
for the calculation of the mean specific heat as well as the
..data obtained using them are mentioned. The mean specific heat

method for mixing in a massive calorimeter. The description of
the device is found in M.M, Popov's "Termometriya i kalorimetri-

TITLE: Investigation and properties of liquii poly-

Communication 1. Investi
gation of composition and properties
of polymethyl~phenyl siloxanes produced by cohydrolyeia
PERIODICAL:-. Plast4cheakiye mas Isy,no. 7, 1962, 211-31
TEXT: The authors made the first attempt,to deterraine the composition of
polyorganouiloxanes 'resulting from various methods of synthesis, by means
of combined molecular and vacuum rectification in spray and packed towers.
An apparatus developed by F. W. Melpolder et al. was used* Separation
is conducted under high vacuum. The apparatus may work either intermittent-
ly or continuously. With infinite reflux the efficiency of the stills~is

of,a mothyl.:phenyl'dichlorosilane-trichlordailane mixture (3:2.2) at-
96-1000C in acid solution is investigated. The product was thermally

mainly of linear methyl phenyl tetrasiloxane with small amounts of methyll
tri- and methyl phenyl pentasiloxane, fraction III of linear
methyl phenyl 3iloxane withj Si atoms per molecule, and fra6tion IV of
linear methyl.phenyl siloxants mixed with 6 and 7 Si atoms per molecul e
besides small amounts (3-97"o') of cyclic methyl phenyl ailoxanes. Four
.:linear-Dolymethyl phenyl siloxanes were isolated and characterized, the
first three of which have not previously been described in publications:

sodium butadiene rubbers,on its supramolecular structures van investigated. Vul-
,canized rubber with more ordered structure van found to possesi superior mechanical
properties. Change in mixing temperature (in the range of 25-70C) does ~ot Big-

A13STRACT: A 10-cc test sample is, taken for the determination of Au in cya-
nide electrolytes that contain 3-4 g/1 of the metal. For concentrated
electrolytes containing 17- 36 g/1 Au, a 10-cc test sample is.diluted
to 500 cc with water and a 20-50 cc aliquot is used for the, analysis.
The test sample is neutralized with HCl to phenolphthalein and heated
to boiling. 50 cc of 101o hydrazine hydrochloride are added to. the
boiling solution and the boiling is continued to the complete reduction,
of -Au according to the following reaction: 4KAu(CN)Z+ NZH4'ZHC1

level. The_Au precipitate is filtered off, washed with hot water,
cUied and calcined at-8000. To the filtrate am added 25 ul of
10% solution of NAf.211CI and the mixture is boiled to check
coiOleteness of precipitation. The calciaed precipitate is dis-
solved in 5 ml of aqua regiat evaporated, and the resicbte is eva-
porated to dryness, 3 times, with 1-2 ml dilute HCl -'1:3)- 3 ml
of dilute HCI (1:50) are added, followed by 2-3 drops of a hydro-
chloric acid solution of Br.1, and the mixture is evaporated to
dryness. The residue is diluted to 30-40 mly combined with 0.1 g
K-bifluoride, 2-3 drops of o-dianisiclin solution (10 mg in 10 ml
HCI, 1:300) and titrated, after 5 minutesp with a solution of
hydroquinone (0-4180 g dissolved in 500 ml water, acidified with
10 ml cimcentrated HC1, and diluted with dilute hydrochloric acid,
1:300, at a ratio of 1:100) until a colorless or faintly bluish
solution is obtained (2AUC13 + 3C4 H,~,C., 3111 Hf O.A+ 2Au + 6Hcl)
