按照反应系统分类,分别介绍了液-液相转移催化剂、固-液相转移催化剂、三相相转移催化剂和反相相转移催化剂的催化机理、常用的表面活性剂类型,并给出了一些应用实例。最后提出了目前存在的问题并对其应用前景进行了展望。
Mechanism for action of phase transfer catalyst ( PTC ) ,including liquid - liquid PTC, solid - liquid PTC, three -phase PTC and reverse phase PTC as well as types of commonly used surfactant were reviewed with some practical application examples presented. Currently existihg problems and outlooks for applications in this field were prospected.
