Although many researchers have studied the synthesis of allyl phenyl ether by phase-transfer catalysis, no studies have used it in membrane reactor up to now. The purpose of this paper is to combine the studies of membrane reactor and phase-transfer catalysis. The membrane was used to stabilize the aqueous/organic interface at a fixed position, also the quaternary ammonium ion in the membrane was used as the catalyst to partake in the reaction system directly, and so it can also separate the product and reactants at the same time. A theoretical model is also presented.

中文摘要对於利用相间转移触媒催化技术来合成丙烯基苯基醚的反应，已有不少专家学者研究过，而至今还无在薄膜反应器中进行此反应之研究，本研究则是要结合薄膜反应器与相间转移触媒两者之特性，固定水油两相之界面，并且利用薄膜上的四级铵离子为触媒，直接在反应系统中参与反应，并同时分离产物及反应物，进而推导出相关之理论模型。
