for the production of dyes. Theme compounds are benzene, toluene, Xylenes,
naphthalene, anthracene, acenaphthene, carbazole, and others. In addition
to the coke-chemical raw materials, various acids, alkalies,-salts, chlorine,
bromine, asmonia and other chemical products are used in the production of
dyestuffs.
An efficient aniline dye industry has been built up in our country during
the Soviet regime. In 1954 it will produce 27 new valuable dyestuffs.
Increasing the production of stable and bright organic dyestuffs of high
quality enables us to meet the growing demands of various branches of industry.
