FIELD: chemistry.
SUBSTANCE: pitch coal crushed to particle size of 500 mcm is added to water-soluble salts of high-molecular compounds and then high-molecular organic acids consisting of a water-insoluble component in form of hydrogel and soluble component in form of a paste, the components are combined and then reacted with glacial acetic acid in the presence of lead (II) acetate to obtain a carboxyl-containing resin at the output through extraction, where the said resin contains oxygen-containing organic compounds with lower molecular weight.
EFFECT: obtaining oxygen-containing soluble organic compounds from pitch coal without using hydrogen at high pressure.
