ABSTRACT:
The present invention is a simplified process for making succinyl acetone (SA). The most preferred embodiment is a one step process that reacts levulinic acid, ethyl acetate, and a base to form SA. Generally, a levulinic acid group may be reacted with an alkyl ester and a base to form SA. Optionally, the reaction may be acidified after completion to remove byproducts.
