METHOD OF PRODUCING FULLERENOLS Russian patent published in 2013 - IPC C01B31/02 B82B3/00 C07C29/00 C07C31/00

Abstract RU 2481267 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing biologically active water-soluble fullerene derivatives - fullerenols, which can be used in engineering, medicine and biology. The method involves reaction of a mixture of fullerenes obtained by extraction from fullerene soot and containing 97-99 wt % light fullerenes and 1-3 wt % heavy fullerenes, with a hydroxide of an alkali or alkali-earth metal and a catalyst - tetrabutylammonium hydroxide or tetraisopropylammonium hydroxide.

EFFECT: design of a safe method of producing fullerenols with fewer makeovers.
