| Abstract: | The reaction conditions of supported heteropoly acid catalyst was examined in a fixed-bed reactor.The result shows that the catalyst has two kinds of acid center, with high activity when pretreated in 150～160℃,and high sensitive to water, and can promote the alkylation reaction even in low temperature and produce more 2-phenylisomer. Furthermore, it has potential industrial utility due to its long catalytic stability. |
