FIELD: organic chemistry, chemical industry, chemical technology. SUBSTANCE: method involves interaction of carbon black with diazonium salt in proton medium, for example, in water or alcohol. Diazonium salt is formed in the interaction process with carbon black from primary amine of the general formula AyArNH2 where Ar is aromatic or heteroaromatic radical; A is a substituent at this radical, for example, functional group, linear, branched or cyclic hydrocarbon radical; y >= 1; at y > 1 A can be similar or different and taken among group including: OR, COR, COOR, OCOR, carboxylate salt, CN, NR2, SO3H, sulfonate salt, OSO3H, OSO-3, NR(COR), CONH2,NO2, OPO3H2, mono- or dibasic phosphate salt, PO3H2, mono- or dibasic phosphonate salt, N=NR, salts, SNQ, SO2NQ, CO2NQ,, S-(1,4-piperazindiyl)-SR, 2- (1,3-dithianyl), 2-(1,3- -dithiolanyl), SOR and SO2R; R and R' mean hydrogen atom, branched or linear alkyl, alkenyl or alkynyl, aryl, heteroaryl, alkylaryl or arylalkyl; Q means (CH2)w, (CH2)xO(CH2)z, (CH2)xNR(CH2)z or (CH2)xS(CH2)z, wherein x, w and z have values from 1 to 6. Invention can be used in preparing filling agents for plastics, paper, rubber mixtures, fibers and textile compositions. EFFECT: improved preparing method. 10 cl, 23 tbl
