TEXT: Monomeric trio-(triphenyl-ailoxy) aluminum (I) was economically
synthesized for the first time from 0.02 M triphenyl-ethoxy silane (II)
and 11 g sodium aluminate solution (III): (C 6H5 3 Sioc2H5 + H20 ---90

+ H20. A mixture of II obtained by distillation in vacuo at 196-201 C
and reprecipitation with petrol ether, along with III containing
19.2% Al2 03 and ~0-3% Na 20, was stirred for 40 min without heating and
then for 4.5 hre at 50-6000. 1 forming at the surface of the mixture as
a white solid substafice was separated. The yield was 35% (related to II)

tetra-(triphenyl-ailoxy) sodium polyalumoxane (IV), a white powder
insoluble in organic solvents and stable to alkalies; yield 55 - 60',A.
The new substances were subjected to thermal, spectral and x-ray aniilyses.
The thermogram of I revealed 3 exothermic effects corresponding to a
7subsequent.splitting-off of the triphenyl-ailoxy groups at 500, ()00, and
7000C. This is confirmed by the thermogram of IV which shows two
exothormic effects due to the 2 triphenyl-ailoxy groups bound to Al and
.1 endothermic effect produced by_dehydration. The IR spectra indicatel
an absorption maximum at 1065 cm I characteristic of the SiOA1 .-roup an-]
further maitima at 700, 740, 997, 1123, 1432, and 1596 cm-1which are
indicative of phenylated silanes and siloxanes. X-ray analysis showed
that I and IV have crystal-line structure. There are 2 fi.gures.

LBSTWT; Because the recommended method of silicon determination
VY fusion in a bomb is not always expedient,, the authors investigated
and proposed other methods of Si determination in silico-organic
compounds (BOO): most precise, but time consuming, is wet oxydation
by a mixture of oleum and fuming nitric acid In quartz flasks with
subsequent Si-determination by gravimetric and volumetric methods*
SOO wddation in a platinw, oricible with the same acids is less
precise than in a quartz flask but the volumetric tests Is faster,

A fast method Is based on the oxidation of 500 by a mixture of sul-
furic and chromic acid in a stream of oxygen but it cannot be used
with volatile substanceso Si-determination by fusing In bomb with
sodium peroxide corrodes the bomb and contaminates the substances
Some improvements, which give greater analytical accuracy, consist
in oxidizing In open crucibles cooled In liquid air and in the use
of sodium fluoride Instead of ammonium fluoride In acidimet'ric
titration. The use of nickel or Or-NI bombs instead of steel is
recommended to avoid contaminations About 40 mono- and polymer SOO
were analyzed by the authors using the most appropriate of the
above methods and the resul-I '6s are consolidated in tables,. The
methods are explained and described In details Origo art& has

ABSTRACT: The article describes two methods for the determination of
titanium, a titration (complexometric) and a spectroscopic method. In
the titration method, a weighed portion of the compound to be analyzedg
containing 10-15 Mg of titanium, is introduced Into 5-7 M1 of
concentrated sulfuric acid, The mixture Is heated for 10-15 minutes up
to the evolution of H2301L vapors. The solution Is cooled to 90-1000 and
complete mineralization i5f the weighed portion is carried out with
ammonium persulfate. The solution is cooled and 30 ml of water are

carefully added and the solution is boiled for 5-10 min to decompose the
ammonium persulfate. The silicle acid is filtered off and the silicon
is determined by weighing in the form Of S102. Final titration of the
titanium in the filtrate is done with a 0,05 M solution of ZnS%. The
relative error of the method does not exceed 2.5%. In the spec rosco Ic
method, the titanium is determined in the form of tetrabutoaxti-anillT-
and silicon In the form of tetraoi silan I In this methods the standard
relative error in the determination is 2.2% for titanium and V1. for
silicon. Comparative results by the two methods are shown in tabular
form. According to the article, the spectroscopic method 13 to be

ABSTRACT: Current methods for determining Al and Si in Al- and Si-containing
organic compounds (ASOC) require complete mineralization of such compounds and are
time-consuming. The authors have developed two accelerated methods for determining
these elements in ASOC. The first method is the determination of altminum by titra-
tion involving complex ion formation. The -'-'--Si-0
