ABSTRACT:
A process is provided for the production and purification of cyclic esters in which the purification includes the introduction of an aqueous solvent into a cyclic ester containing composition and allowing two phases to form. A first phase includes cyclic esters and any organic solvent, and a second phase includes the aqueous solvent and impurities.
