| 摘 要： | <正> 高分子催化剂以许多独特的优点和功能日益受到人们的重视,我们曾将四氯化钛与聚苯乙烯反应制成一种比较稳定的复合物,它对酯化、缩醛等有机反应有良好的催化效能”,也可作为α-甲基苯乙烯正离子聚合的有效催化剂,但重复使用性能欠佳,妨碍实际应用,本文应用市售弱碱性聚苯乙烯型离子交换树脂与四氯化钛反应,制成一种更

| Abstract: | Dry beads of polystyryl weak basic anion ex-change resin (commercial, 16-50 mesh, exchange value ≥ 5 mtnol/g, activated groups -NH3,-NH-) are conbined with titanium tetrachloride in chloroform to form a stable complex containing 36.8% of chlorine which correspond to 2.59 mmol TiCl4/g complex beads. The complex can be used to catalyze a lot of organic reactions in high yield, such as esterifications, acetalizations, ketal formations and etherification, and can be reused. |
