Zusammenfassung: | Process for recovering dialkyl terephthalate. The process can include exposing the polyester composition to one or more glycol to depolymerization conditions, thereby providing one or more depolymerized products. The one or more depolymerized products may be exposed to an alcoholysis process to recover the dialkyl terephthalate. Alternatively, one or more glycols may be recovered and reused in subsequent dialkyl terephthalate recovery or other processes.
回收对苯二甲酸二烷基酯的工艺。该工艺可以包括将聚酯组合物暴露于一种或多种二醇至解聚条件,从而提供一种或多种解聚产物。可以将一种或多种解聚产物暴露于醇解工艺以回收对苯二甲酸二烷基酯。可选地,一种或多种二醇可以回收并在随后的对苯二甲酸二烷基酯回收或其它过程中再利用。 |
