摘要

Alkenylations of p-xylene with phenylacetylene over various zeolites like HY, H-Beta, and H-ZSM-5 have been performed. Effects of the types of zeolite and pretreatment conditions, such as ion exchange times, calcination temperature, and HC1 concentration for dealumination, on the catalytic properties have been studied. Moreover, the HY, H-Beta, and MCM-41 supported both H_3PW_(12)O_(40) and H_3SiW_(12)O_(40) solid acid catalysts, which were employed to promote the alkenylation reaction. It has been found that H_3PW_(12)O_(40)/MCM-41 mesoporous solid acid could become a promising catalyst for alkenylation of p-xylene. The possible mechanism of alkenylation of p-xylene with phenylacetylene over solid acid catalysts is also proposed.
