摘　　要：介绍了乙二醇锑催化剂在200 kt/a聚酯装置生产中的应用。与醋酸锑相比,避免了刺激性气味, 减少了催化剂的使用量,降低了成本。聚合纺丝工艺条件不变,操作方便,产品质量较好。The application of antimony ethylene glycalate catalyst in a 200 kt/a polyester plant was introduced. Antimony ethylene glycalate taking place of antimony acetate can avoid irritant odor, decrease catalyst consumption and reduce production cost.The spinning conditions remained unchanged, the operation was convenient, and the product quality was fairly good when using antimony ethylene glycalate as the catalyst.
