摘要
本文以β-环糊精为相转移催化剂，以过氧化氢作氧化剂，以乙酸铁为催化剂直接催化氧化苯合成苯酚．其最佳工艺条件：在pH=3、苯5mL、H2O2 12mL，相转移催化剂β-环糊精0．1mmol时，反应时间1．5～2h，反应温度50℃左右，乙酸铁用量3．2mmol．
This paper designed the experiment of using β-cyclodextrin as phase-transfer catalyst, hydrogen peroxide as oxidant, ironic acetate as catalyst, direct catalyzed oxidation of benzene to phenol reaction The optimal conditions： pH = 3, benzene 5 mL, hydrogen peroxide 12 mL, β-cyclodextrin 0.1 mmol, reaction time 1.5 -2 h, reaction temperature 50 ℃ , the use of ironic acetate 3.2 mmol.
