摘　　要：研究了钛硅分子筛(TS-1)催化苯制苯酚的反应中溶剂、温度、时间、催化剂以及H2O2(30%)的用量对反应的影响.结果表明,在经2 mol/L的醋酸铵预处理的TS-1为催化剂,以丙酮为溶剂,在56.92℃下,以质量比苯∶双氧水∶TS-1=78∶41.14∶22.18,反应时间5.37 h为条件,苯酚的产率可达到13.05%.The hydroxylation of benzene to phenol with 30 % （w） Hz Oz over TS-1 molecular sieve catalyst was studied. The influences of various parameters such as solvent, temperature, time, catalyst, quantity of HzOz to benzene on the reaction were investigated. The results show that when the TS-1 was anticipated by ammonium acetate（2 mol/L）, the best solvent is acetone, the optimal temperature 60℃, the reaction of time 6h and the quantity ratio benzene ： H2O2 ： TS-1 = 78 ： 41.14 ： 22.18 can achieve the high production rate of 12.53%.
