SUCCINIC ACID OR ITS SALTS PRODUCTION METHOD Russian patent published in 1999 - IPC

Abstract RU 2129540 C1

FIELD: industrial organic synthesis. SUBSTANCE: succinic acid or its salts are produced via hydrogenation of maleic anhydride or maleic acid or its salts in water in presence of palladium-containing catalyst on carrier, more particularly palladium-nickel catalyst with Pd:Ni ratio 1:(0.5-5) or palladium-iron catalyst with Pd-Fe ratio 1:(0.1-6). EFFECT: significantly increased productivity of process per unit weight of palladium component. 1 tbl, 16 ex
