摘　　要：采用一种新型耐热性树脂催化剂，研究了苯酚与异丁烯的烷基化反应，计算出该反应的表观反应速率常数及表观活化能，并与工业上普遍使用的７３２＃树脂催化剂进行比较。由于其优良的热稳定性，选择性及催化活性，该催化剂具有良好的应用前景。The tertbutylalkylation of phenol with isobutene was carried out in the presence of a new type catalyst, which has the characteristics of cationexchange resin with high thermol stability. The apparent reaction rate constant and the apparent activation energy were calculated, and the catalytic activity of the resin catalyst was compared with that of 732# cation-exchange resin catalyst which is commonly employed in industrial practice. In view of its high thermol stability, selectivity, and catalytic activity, this catalyst shows considerable promise for application.
