A PROCESS FOR PREPARING SUCCINATE ESTER

This invention relates to a process for preparing succinate ester from a succinic acid salt present in a fermentation broth. In the first stage of this invention, renewable carbon resources are utilized to produce succinic acid in the form of a succinic acid salt through biological fermentation. The succinic acid salt present in the fermentation broth is subjected to double displacement reaction with a strong acid leading to the release of succinic acid. Succinic acid is recovered by fractional crystallization integrated with an alcohol washing step and subjected to esterification reaction to produce succinate ester which is purified by fractional distillation. The succinate ester thus obtained is converted into 1,4-butanediol, gamma-butyrolactone and tetrahydrofuran through hydrogenation reactions. The succinate ester can also be hydrolyzed to yield highly pure succinic acid.

PROCESSES FOR PRODUCING CARBOXYLIC ACIDS FROM FERMANTATION BROTHS CONTAINING THEIR AMMONIUM SALTS

Process for the preparation of carboxylic acids like succinic acid (SA) from their correponding biologically-produced ammonium salts (like DAS) and / or amides and / or imides. The process involves reacting the biologically-produced derivatives at high temperature, removing ammonia and water, crystallizing the carboxylic acid obtained and recycling the mother liquor to the reaction system.

METHOD FOR PREPARING AMMONIUM SALTS OF FUMARIC OR SUCCINIC ACID

An improved process for preparing ammonium salts from fumaric or succinic acid, is described. The method consists of neutralizing the corresponding acid carbonate or ammonium bicarbonate at a molar stoichiometric or greater than the stoichiometric ratio of 4-5% in a saturated aqueous solution of the synthesized salt at a temperature not exceeding 40° C., followed by separation of the product and drying at a temperature not exceeding 70° C. After separation of the ammonium salts, the filtrate can be re-used. Isolation of the product is usually carried out by cooling the reaction mixture to a temperature of 15-18C°. The product comes out in almost crystalline form. Saturated aqueous solution of the synthesized salt is formed by the interaction of carbonate or ammonium bicarbonate with the appropriate acid at a temperature not exceeding 40° C. It is possible to obtain cleaner salt concentration weighing more than 99% and not yielding lower than 98%. The method allows for an increase in the yield of targeted products and ensures their consistent high quality due to their formation in crystalline form.
