ABSTRACT:
A process is provided for the continuous or semi-continuous production of hetero-macrocyclic compounds including lactones and cyclic esters. The process involves the catalyzed depolymerization of linear polyesters at elevated temperature and under reduced pressure in the presence of a specified amount of monocarboxylate moieties while providing top-to-bottom mixing throughout essentially the total volume of the reaction mass.
