Abstract
A process for the preparation of a dialkyl succinylsuccinate, which comprises: (a) preparing a dialkyl succinylsuccinate di(alkali metal) salt by reacting a mixture consisting essentially of an alkali metal alcoholate, an aliphatic alcohol and an excess of a liquid dialkyl succinate under anhydrous conditions at an elevated temperature; (b) removing the aliphatic alcohol from the reaction mixture; (c) separating the solid dialkyl succinylsuccinate di(alkali metal) salt from an anhydrous supernatant liquid; and (d) neutralizing the dialkyl succinylsuccinate di(alkali metal) salt to yield the dialkyl succinylsuccinate.
