摘要
介绍了3类固体超强酸,主要就其成酸机理、制备、改性方法、制备过程对催化剂活性的影响等进行了探讨。总结了3种酸性中心模型,同时探讨了酯化反应中催化剂的酸强度、酸醇物质的量比、带水剂的量等因素对酯化反应的影响。指出了今后固体超强酸催化剂的发展方向。
Three types of solid superaeid are introduced, mainly on the acid formative, preparation and modified methods, and the effects of preparation method on the catalysts activity. Three species acidic center models are summarized, and the effects of the acid strength in supersolid catalyst, the mole ratio of acid to alcohol, water-carrying agent amount, etc. on esteri fication are explored. Finally, the development direction of solid superacid catalyst is pointed out.
