METHOD OF PRODUCTION OF THE BROMINE DERIVATIVES OF THE FULLERENE C Russian patent published in 2007 - IPC C01B31/00 C07F13/00

Abstract RU 2307788 C2

FIELD: chemical industry; methods of production of the bromine derivatives of fullerene С₆₀.

SUBSTANCE: the invention is pertaining to the method of production of the bromine derivatives of fullerene С₆₀. The process consists in the interaction of the bromoform and the tetra bromomethane with fullerene С₆₀ at presence of the rhodium-containing catalyst - Wilkinson's complex [RhCl(PPh₃)₃] at the temperature of 100°С within 10-20 hours, at the molar ratio of [Rh]:[C₆₀]:[CHBr₃ or CBr₄]= 1:100:100-500. The technical result of the invention is the increased output of the product, the reduced amount of the wastes, the insignificant consumption of the catalyst.

EFFECT: the invention ensures the increased output of the product, the reduced amount of the wastes, the insignificant consumption of the catalyst.
