Abstract
Abstract Lewis acidic ionic liquids were used to catalyze the reaction of epoxypropane with POCl 3 . Considering the lower cost and catalytic activities, we concluded that [Et 3 NH]Cl/AlCl 3 was the most attractive ionic liquid from an economical point of view. But it would be easily inactivated because of sensitive to water and air. Moreover, it could not be reused easily because of difficulty recovery in the reaction. However, supporting [Et 3 NH]Cl/AlCl 3 catalyst could resolve above problems. Supporting [Et 3 NH]Cl/AlCl 3 catalyst could be separated by filter easily and reused 5 times in 98% yield. Furthermore, the catalyst was applicable to other epoxy ether cleaving reactions.
