Improvements in the processing of coal tar and its fractions
As soon as UKhIN was founded it took on the urgent problems of raising the technical standards of coal tar, fraction and pitch processing and extending the range of products to meet the demand from the expanding allied sectors of industry (chemical, organic synthesis, electrodes, etc.). One important research topic at UKhIN was the production of individual substances and technical products from various feedstocks. The results included the first production in the USSR, on an adequate scale, of products such as acenaphthene, anthracene, carbazole, phenanthrene, diphenylene oxide, fluorene, ..cap alpha..- and ..beta..-methylnaphthalenes, indole, acridine, pyridine, ..cap alpha..-picoline, quinoline and its derivatives, phenol, cresol isomers, etc. For many years, the UKhIN program included work relating to the production of technical and refined naphthalene and the equipment needs. The results provided the basis for UKrNIIkhimmash designs of improved continuous apparatus for naphthalene fraction processing. Its adoption has increased labor productivity, automated process control, improved the degree of naphthalene recovery and improved working conditions. UKhIN participated on a large scale in the investigations, with NIOPIK and the chemical plants, to establish the possibility of making phtahlic anhydride from various naphthalene-containing feedstocks and organize phthalic anhydride production. Other important topics have been the catalytic refining of naphthalene fractions and refined anthracene production.
