摘要:
为解决常规钛系催化剂稳定性差、副反应多和制品色相差等缺陷,以钛酸四丁酯钛酸四丁酯(Tetrabutyl titanate, TBT)和醋酸铈醋酸铈(Cerium(Ⅲ) acetate hydrate)为配位金属源,均苯三甲酸均苯三甲酸(1,3,5-Benzenetricarboxylic acid, BTC)为有机配体,采用水热反应法制备了一种新型钛系聚酯(PET)催化剂。利用SEM、FTIR、DSC等对该催化剂的形貌、配位状态和催化等性能进行分析,并用该催化剂进行PET的合成和固相缩聚试验。结果表明:金属原子和有机配体成功配位,形成了一种具有规则孔状结构的钛系复合催化剂,该催化剂应用于PET制备时表现出较高的催化活性。制得的PET切片热性能与常规PET切片基本一致,色相优于常规钛系催化剂制品。固相缩聚试验表明制备所得PET切片能满足纺制涤纶工业丝要求。该研究对改善钛系催化剂性能和实现钛系催化剂在聚酯工业中的进一步应用具有推动作用。
