苯酚烷基化催化剂研究进展

Research progress on phenol alkylating catalyst

苯酚烷基化催化剂的发展经历了由液体酸、氧化物到离子交换树脂的演变过程,沸石分子筛作为新型烷基化催化剂,以其独特的结构和可调变的酸性及孔径等特点,是比较理想的催化剂。综述了苯酚烷基化催化剂的发展过程,探讨了固体酸催化剂的反应机理。

Phenol alkylating catalyst has experienced a succesion of variations from liquid acid to oxide to ion exchange resin, zeolite molecular sieve as a kind of new alkylating catalyst, with it unique structure and characteristics and adjustable sourness, aperture and etc, become a relatinely ideal catalyst. This paper discusses the reaction mechanism of phenal alkylating catalyst, and its developing process would be summarized in this paper.
