CARBONACEOUS MATERIAL Russian patent published in 2011 - IPC C09C1/56 C09C1/44 C09C3/08 C08K3/04 C09D7/12 B82B3/00 

FIELD: chemistry.

SUBSTANCE: modified carbonaceous material with organic groups is obtained by reacting the starting carbonaceous material in form of soot, graphite powder, graphite fibre, carbon fibre, carbon fibrils, carbon nanotubes, carbon fabric, glass-like carbon products, activated carbon or fullerenes with organic compounds. Reaction of the carbonaceous material with organic compounds is carried out without use or formation of diazonium salts during the reaction. The obtained carbonaceous materials may be used in rubber systems, in producing plastic, printing ink, ink, bitumen, concrete or other building materials, or as reducing agents in metallurgy.

EFFECT: invention improves viscosity and surface tension properties of soot dispersions, reduces formation of by-products.
