FIELD: chemistry.SUBSTANCE: invention relates to chemistry and nanotechnology. The method of producing fullerene C84 involves treating coal tar or coal tar pitch with sulphuric acid, washing off unreacted sulphuric acid, the formed sulphonic acids and hydroxyl compounds with water, and the unreacted aromatic hydrocarbons successively with carbon tetrachloride and acetone. Fullerene is then extracted with toluene or ortho-xylene and the toluene or ortho-xylene are distilled from the obtained extract until achieving a moist state of fullerene residue which is dried at temperature of 60-70°C. The obtained fullerene C84 is soluble in benzene, toluene and ortho-xylene.EFFECT: invention enables to obtain fullerene C84 using a cheap and low power consumption method.11 cl, 3 ex |
