COMPLEXING RESIN FOR RHENIUM RECOVERY AND PROCESS FOR ITS MANUFACTURE Russian patent published in 1994 - IPC

Abstract SU 1407009 A1

FIELD: manufacture of absorbing materials. SUBSTANCE: copolymer of 2-methyl-5-vinylpyridine or 4-vinylpyridine, hydrolyzate of acrylonitrile, divinylbenzene and ethylsterene is used as ion exchanger, with their weight mixture ratio being of 16-49: 8-25: 16-47: 10-29, respectively. Process for manufacturing such complexing resin is characterized by copolymerization of vinylpyridine monomer, acrylonitrile, divinylbenzene and ethylsterene followed by hydrolytic oxidation of nitrilo groups with nitric acid solution. EFFECT: increased adsorptive capacity and selectivity of ion exchanger resin. 2 cl, 1 tbl
