摘要：采用共沉淀法合成了一种新的用于苯酚羟基化反应的催化剂铁酸镁( Mg Fe2 O4 ) ,用 XRD、IR进行了表征。考察了溶剂、氧化剂对苯酚羟基化反应的影响。研究结果表明 ,以水为溶剂、过氧化氢为氧化剂 ,铁酸镁催化剂催化苯酚羟基化反应有较高的催化活性 ,并初步提出了反应机理。
A novel catalyst for hydroxylation of phenol, MgFe 2O 4, was synthesized via co precipitation method, characterized by XRD and IR. The effect of solvent and oxidant on phenol hydroxylation were studied. The results indicated that the catalyst magnesium ferrite(MgFe 2O 4) showed higher catalytic activity in the phenol hydroxylation with water as solvent and ozogen as oxidant. Additionally, in this study, A free radical mechanism was proposed to explain the experimental phenomena.
