ABSTRACT:
The invention discloses an improvement to the selective production of dialkyl succinates by the known process of oxidative carbonylation of an olefin with carbon monoxide, oxygen, and an alkyl alochol in the presence of a catalyst wherein the improvement comprises using a sulfone as the reaction solvent. The use of a sulfone, of which sulfolane is a preferred example, results in fast reaction rates and high selectivity to dialkyl succinates even in the absence of a dehydrating agent.
