用离子交换方法制备了 α-Fe2 O3/微孔树脂催化剂 .XRD,TEM和 Mossbauer谱测试结果表明 ,制得的α-Fe2 O3粒子尺寸非常细小 ,其粒径至少在 5 nm以下 .该催化剂在苯酚 H2 O2 羟化制备苯二酚反应中表现出了良好的催化活性 ,在 n(苯酚 ) / n( H2 O2 ) =3条件下 ,苯酚的有效转化率可达到 2 2 .4 % ,产物中邻苯二酚和对苯二酚的物质的量比接近 1 .4∶ 1 ,反应放大 30 0 0倍后羟化活性及产物的选择性基本不变 .与化学沉淀法制得的纳米 α-Fe2 O3羟化活性比较认为 ,造成二者催化活性不同的主要原因是 α-Fe2 O3的粒径发生了变化 The α-Fe2 O3 / microporous resin catalyst was prepared by ion exchange method.The results of XRD, TEM and Mossbauer spectroscopy showed that the particle size of α-Fe2 O3 was very small and its particle size was at least 5 nm The catalyst showed good catalytic activity in the hydroxylation of phenol to H2O2. The effective conversion of phenol reached 22.4% at n (phenol) / n (H2 O2) = 3, The mass ratio of catechol to hydroquinone in the product was close to 1.4: 1, and the hydroxylation activity and the selectivity of the product were almost unchanged after the reaction was magnified to 30000. Compared with the nano α -Fe2 O3 hydroxylation activity that the main reason for the difference between the two catalytic activity is the α-Fe2 O3 particle size has changed
