METHOD OF OBTAINING A HIGHLY CONCENTRATED AQUEOUS SOLUTION FULLERENE Russian patent published in 2019 - IPC C01B32/156 B82B3/00 B82Y40/00 

FIELD: medicine; chemistry.

SUBSTANCE: invention relates to chemistry and medicine and can be used in the manufacture of medicines and cosmetics. First crystalline fullerene, for example C₆₀, dissolved in N-methylpyrrolidone. Resulting solution is mixed with water or an aqueous solution of a stabilizer, which is used as a biocompatible non-ionic surfactant, monosaccharide and / or amino acid, pluronic F-127, L-alanine, rhamnose, glycerin, twin 20 and / or twin 80. This is followed by tangential in-line ultrafiltration of the resulting solution using a semipermeable polysulfone or regenerated cellulose membrane. Excessive dialysis can be performed before ultrafiltration.

EFFECT: invention provides a high colloidal stability of the resulting aqueous solution of fullerene in the presence of salts in the range of fullerene concentrations of 50–3,000 mg/l.
