Title
(EN) “PROCESSES FOR THE PRODUCTION OF TETRAHYDROFURAN, GAMMA-BUTYROLACTONE AND/OR BUTANEDIOL FROM SALTS OF SUCCINIC ACID”
Abstract
(EN) A process for making a hydrogenated product includes providing a clarified DAS-containing fermentation broth; distilling the broth under super atmospheric pressure at a temperature of >100°C to about 300°C to form an overhead that includes water and ammonia  and a liquid bottoms that includes SA  and at least about 20 wt% water; cooling the bottoms to a temperature sufficient to cause the bottoms to separate into a liquid portion in contact with a solid portion that is substantially pure SA; separating the solid portion from the liquid portion; recovering the solid portion; hydrogenating the solid portion in the presence of at least one hydrogenation catalyst to produce the hydrogenated product including at least one of THF  GBL or BDO; and recovering the hydrogenated product.
