Abstract: The p－t－butylcatechol （TBC） was synthesized from catechol， isobutylene and acidic zeolite using as a new catalyst．Effect of process conditions on reaction was investigated． The optimum technology parameters were obtained．The
yield of TBC is above 85% every time when the reaction temperature is140 ℃， the reaction time is 8 h，the mole ratio of catechol to isobutylene is 1:1 .2,and mass fraction of the catalyst is 20% which can be repeatedly used more than 30 times．

Key words: Catechol , Isobutylene , Acidic zeolite , p－t－Butylcatechol

摘要： 以邻苯二酚、异丁烯为原料，酸性分子筛为催化剂催化合成对叔丁基邻苯二酚，探讨了各工艺条件对反应结果的影响，确定了最优反应条件。反应温度 140℃，反应时间 8 h，物料配比 n(邻苯二酚) / n(异丁烯) = 1∶1 .2，催化剂质量分数为 20%，对叔丁基邻苯二酚收率均可达 85%以上，催化剂可重复使用 30次以上。
