对叔丁基邻苯二酚的合成研究

Synthesis of p-t-Butylcatechol

以邻苯二酚、异丁烯为原料,混酸作催化剂催化合成对叔丁基邻苯二酚的新工艺,探讨了工艺条件对反应结果的影响,确定了优惠条件:反应温度125℃,反应时间2h,物料比n(邻苯二酚)∶n(异丁烯)=1∶0.65,催化剂用量为邻苯二酚的0.1%(m/m),对叔丁基邻苯二酚收率可达93%以上。

The p-t-butylcatechol （4-TBC） was synthesized from catechol and isobutylene using a new catalyst. Effect of process conditions on reaction was investigated. The optimum technology parameters were obtained the yield of 4-TBC was above 93%when the reaction temperature was 125℃, reaction time was 2 h, the mole ratio of catechol to isobutylene was 1 ： 0.65, and the catalyst amaunt was 0.1%.
