摘要
考察了固定床反应条件下负载磷钨酸合成直链烷基苯的工艺条件。结果表明:它有两种酸中心,在150~160℃预处理后活性高,对原料中的水敏感;低温活性高,2位产物异构体选择性好,并且在实验室中具有较好的活性稳定性。
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.
