固定床催化体系中苯酚与苯乙烯的反应

The Alkylation of Phenol with Styrene in the Fixed-Bed System

用固定床反应器研究了固体酸催化的苯乙烯与苯酚的烷基化反应，表明选择合适的反应条件有利于生成较为有用的对位产物．该反应体系不仅具有釜式反应体系的活性好、选择性高的特点，还可大大减少苯酚用量，简化了产物的后处理，有很好的应用前景．

The alkylation of phenol with styrene catalyzed by the solid acid in the fixedbed reactor was studied. In this system,choosing suitable reaction conditions is favourable for the production of para-α-methylbenzyl phenol. This catalytic system has the same advantages as still-reactor.Furthermore, the amount of phenol can be reduced greatly,which simplifies the after-treatment of products.
