ABSTRACT:
A process for recovering dimethyl terephthalate (DMT) comprises the steps of: providing a dimethyl terephthalate stream including dimethyl terephthalate, glycols, and coordination compounds; acidifying the coordination compounds to disassociate the ligands from the metalions; separating the ligands from the metalions; separating the dimethyl terephthalate from the glycols; and recovering the dimethyl terephthalate. Additionally, the process may include the step of basifying the metalions to precipitate the metal; and recovering the metal.
