TEXT: After the 21st Congress of the CPSU. many changes were made in
the plants of the Stalino Economic Rayon for the purpose of increasing
produn,tion and raising the quality. The biggest installation in the
world for continuous steel casting was put into operation at the
Stalinskiy metallurgichaskiy zavod (Stalino Metallurgical Plant 9 a
calcining process in quaeiliquid charge was introduced at the Nikitov-
skiy rtutnyy kombinat (Nikitovka Mercury Kombinat), production of heavy
automatic lathes of the type K)K-36 (KZh-,36) and KA-37 (M-37) as
well as K >R-,25 (M-25) was started at the Kramatorskiy zavod

zavod im. 15--letiya LKSKU (Stalino MachLne Construction Plant imeni
15th Anniversary LKSUU). It was however2 established that some plants
of the Stalino sovnarkhoz do not pay enough attention to quality-qAand
the activity of thes4 plants was therefore investigated by the Stalin-
skaya gosudarstvennaya kontrolinaya laboratoriya po izmeritellnoy
tekhnike (Stalino State Control Laboratory for Measuring Technology).
The deficiencies established thereby are mentioned in the present paper)
and it -is stated that a deviation from the standards laid down is "main-
ly the reason for a deterioration of quality. The following plants are
mentioned and criticized: Konstantinovskiy zavod ogneupornykh izdeliy
"Krasnyy Oktyabr" (Konstantinovka Plant for Refractories "Krasnyy
Oktyabrl"), YasinovJ-s-klyzavod gornoprokhodcheskogo oborudovaniya

of drawings: "System of Administration of Drawings" and "Drawings in
Machine Construction". A change of the OCT(OST) 10210-40 standard takes
place at the "Krasnyy Oktyabr"I Plant and there is no OST NKTP 5853/140
standard "Methods of Measuring the Blunting of Angles and Ribs in Re-
fractories" at that plant. There are various inaccuracies in the tech-
nical documentation of the Yasinovatays, Plant, with reference to
GOST 977-53, GOST 1284-45, BH-46-51 (VN-46-~-51); in some a.;:awings, for
example, the weight of individual parts is not mentioned OK1-13-0101
(DKI-13-0101), AK4-148 (DK4-148)),,some drawings of bushes of the type
ARI-0212 (DK1-0212) and lids of the type AKI-0206 (DKI,-0206) are used
without introducing the essential modification; technical references
for the crusher of the type AA ~-lM (DDZ-lM) are missing. At the Plant
imeni Artem) articles are produced according to a modified GOST 2634-44
standard, instead of the valid GOST 2634--59 standard, and certain notes
are missing in the drawings for suspension insulators of the type
M-4-5 (PM-4-5)- Furthermore, technological discipline is not kept up
in the plants being criticized, i.e.2 the production process is modified
arbitrarily, and the quality of production is thus impaired. At the

TITLE: Some Organosilicon Liketodicarboxylic Acids
PERIODICAL: Zhurnal obshchey khimii, 1961, Vol- 31, No. 1, pp. 234 - 238
TEXT: Following the paper of Ref. 1 on the acylation of organosilicon
compounds,-the authors in the present paper studied the synthesis of
organosilicon diketodicarboxylic acids. Phthalic and maleic anhydride
were used as acylating agents, and methyl-phenyl-siloxane groups were
introduced into the molecule of diketodicarboxylic acids at the same time.
When changing the ratio of the acylation product (I) to methyl-phenyl-
dichlorosilane in the hydrolysis process, organosilicon diketodicarboxyl.ic
acids resulted, which contained X methyl-phenyl-siloxane groups (X - 1, 2, V~
3, 4, 5 or 10). These acids are well soluble in alcohol, acetone, ether,
benzene, toluene, CC14, and chloroform; in unpurified and purified state
they are viscous, transparent liquids, and do not crystallize even on
prolonged standing at room temperature. Their viscosity is related to the
number of methyl-phenyl-siloxane groups in the molecule; it incraases with

Abstract VI. A simple method was worked out for quantitative de-
t~~rmiziation of Si in organosilicon compounds (OSC). mi-
neralization of analyzed substance is effected by wet pro-
cedure with a iuxture of oleum or H2S04 and fuming H'103
With most OSC minQralization occurs readily, only lower al-
kyl silanes (in particular tetramethyl silane) exhibit con-
siderable stability. To avoid losses in the case of more

volatile halogeiiated silanes,the authors recommend to
weig~i the latter in cooled pyridine. Determination of
Si is effected by acidiinetric method based on formation of
K SiF6 in acid medium. Use is made of mixed indicator

(methyl red and bromcresol green at a ratio 6-5).
der to obviate hycholysis oZ K2SiF, at high pH values it
is necessary to carry out the titrktion vith a small volu-
me of liquid being titrated and in a solution saturated-
with K ions. By the above-stated method the Si content
was determined in several hut7dred samples of osC with ve-
ry good results.
VII. The authors have developed a reliable method for de-
termination of halogen in OSC of the type R SiX4 n (R --
alkyl, aryl or hydrogen, X -- halogen). Thne dete-rmination
is carried out as follows: The substance is hydrolyzed
