Description: 
This institute is acknowledged as one of the most important in 
chemical research in the Soviet Union. 
A large percentage of its work has been devoted to applying various 
methods of radio- and electrochemistry to analytical chemistry. Past 
research involved developing methods for the radiometric determination of 
iodides, trilanometric titration of zinc in organic compounds, isotopic 
determination of small amounts of copper, and adaption of scintillation 
spectrometers for the determination of radioactive impurities. The 
Institute's research in plastics and elastomers--including methods of 
synthesis and studies of properties--resulted in the development in 1932 of 
methods for the production of synthetic rubber, and the later development 
of anticorrosive plastic coatings such as Ftoroplast-3. 
A laboratory of the Institute has studied and prepared many organic 
fluorine compounds to the extent that they have been able to supply them to 
other institutes and laboratories for various research projects. 
The metallurgical research staff has worked on the passivity and 
corrosion of different metals in various media, especially fluorine. They 
were the first in the U.S.S.R. to develop a process for ornamental and wear- 
resistant coatings. The Institute's Crimean Laboratory has also developed 
methods for producing manganese. 
Continued research on corrosion and corrosive liquids has resulted 
in the development of several types of flowmeters to aid their work. Some 
research, although not too extensive, has been done in powder metallurgy 
and refractories. Considerable research has been published on hydrogen 
overvoltage in different palladium alloys. 
Recent work of the Institute has considered the luminescence pro- 
perties of a wide range of compounds (plastics and selenium compounds) with 
associated studies on the synthesis of phosphors and luminophors. 
The Institute publishes a Trudy and also grants both the Doctor's 
and Candidate's Degrees.
