英文摘要: The epoxidation of styrene catalyzed by a reaction-controlled phase transfer catalyst [(C18H37(30%)+C16H33(70%))N(CH3)(3))(3)](3)-[PW4O16] with H2O2 in a biphasic medium was investigated. Under certain conditions, the selectivity for styrene oxide was 95%, the conversion of styrene based on H2O2 was 85%, and the reaction time was less than 1 h. During the reaction, this catalyst powder formed soluble active species by the action of H2O2, was recovered as a precipitate, and was reused after H2O2 was used up. After two times recycling, the catalyst kept almost the same activity.
