以[（C18H37）2（CH3）2N]7[PW11O39]为基础，研究了一种新型的烯烃环氧化温控相转移催化体系。反应在乙酸乙酯的非氯化溶剂中与过氧化氢进行。该催化剂易于回收，重复使用10次，活性和选择性均无损失。
A novel temperature-controlled phase transfer catalytic system based on [(C18H37)2(CH3)2N]7[PW11O39] for olefin epoxidation was demonstrated. The reaction was conducted in a non-chlorinated solvent of ethyl acetate with hydrogen peroxide. The catalyst was easily recovered and reused even ten cycles without loss in activity and selectivity.
