METHOD OF PRODUCING CALCIUM SUCCINATE Russian patent published in 2015 - IPC C07C55/10 C07C51/285 B01J23/22 

FIELD: chemistry.

SUBSTANCE: method of producing calcium succinate is carried out by oxidising an organic substance with a peroxide in the presence of a catalyst, the organic substance used being furfurol and the peroxide being hydrogen peroxide. The process is carried out in the presence of vanadyl sulphate and calcium carbonate until the furfurol and peroxides are exhausted. Crystalline acidic calcium succinate is separated from the pre-filtered oxidate while cooling. The disclosed method aims to utilise industrially available reagents, including a safer oxidising agent and an affordable catalyst.

EFFECT: simple and cheaper process owing to use of industrially produced cheaper hydrogen peroxide and vanadium sulphate, safer process owing to use of hydrogen peroxide instead of sodium peroxide as the oxidising agent.
