摘要
本文以大孔强酸性苯乙烯系阳离子交换树脂与四氯化钛反应,合成了一种稳定的新型高分子固载化路易斯酸催化剂,并在羧酸酯、缩醛、缩酮、醚类等化合物合成中得到应用。该催化剂显示了易分离、使用方便、无污染和可重复使用等特点。
Ion exchange resin-supported titanium tetrachloride was synthesized in CS2, a stable complex catalyst containing 5.76% Ti was obtained. The polymer-supported catalyst can be used to catalyze many organic reactions with high yield, such as esterification, actalization, ketal formation and etherification. The catalyst is also effective for aldol condensation. The title catalyst can be reused for at least 9 times.
