FIELD: chemistry.
SUBSTANCE: invention relates to chemical industry and medicine and can be used in producing concrete plasticisers, microbiocides with anti-HIV properties which are not cytotoxic and modifiers of epoxy composites. Fullerene-polysulphonic acid is a water- and alcohol-soluble product of reaction of coal tar and coal tar pitch with sulphuric acid with concentration of at least 80%. Unreacted sulphuric acid formed when treating sulphonic acid and unreacted aromatic hydrocarbons are successively washed off with toluene, carbon tetrachloride and acetone to pH 6.5-7.0. Fullerene-polysulphonic acid is then extracted with ethyl alcohol in Soxhlet apparatus. Ethyl alcohol is distilled from the alcohol solution of fullerene-polysulphonic acid to dry residue.
EFFECT: invention enables to obtain fullerene-polysulphonic acid using a simple method using cheap and readily available reactants.
