ABSTRACT:
A process for recovering dimethyl terephthalate (DMT) is disclosed. The process includes the steps of: (a) providing a DMT stream, the DMT stream including DMT, catalyst, and ethylene glycol; (b) adding a solvent to the DMT stream, the solvent being immiscible with water and miscible with DMT; (c) adding water to the DMT stream; and (d) forming two phases, a first phase of the solvent and DMT, and a second phase of water, ethylene glycol, and catalyst.
