METHOD OF MANUFACTURING DICARBOXYLIC ACIDS AND DERIVATIVES FROM COMPOSITIONS COMPRISING KETOCARBOXYLIC ACIDS

摘要

A crude composition comprising a ketocarboxylic acid such as levulinic acid, derived from biomass in an aqueous phase comprising impurities, can be efficiently converted in high yield to the corresponding dicarboxylic acid, such as succinic acid, which can be purified and dried.
