METHOD FOR PREPARING SUCCINIC ACID Russian patent published in 2004 - IPC

Abstract RU 2237056 C1

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to the improved method for preparing synthetic succinic acid that exhibits biological activity related with that of succinic acid prepared by pyrolysis of amber and using as a drug or nutrient biologically active supplement. Method is carried out by hydrogenation of maleic anhydride, maleic or fumaric acid in an aqueous medium in the presence of palladium-iron catalyst. Catalyst represents palladium complex compounds and iron water-soluble compounds applied on carbon carrier by adsorption. Process is carried out in the presence of palladium-iron catalyst prepared in using palladium complex compounds and succinic, maleic or fumaric acid as palladium complex compounds and their adsorption on carbon carrier in the formation point. Prepared succinic acid has biological properties related with properties of "natural" acid: diuretic, cardiotonic, anti-arrhythmic, antihypoxic and adaptogenic effects.

EFFECT: improved preparing method.
