| 摘 要： | 用程序升温还原方法合成了Cu-Ni/γ-Al2O3催化剂,使苯直接羟基化合成苯酚。对该反应过程中,反应温度、反应溶剂、反应原料的不同配比等因素的影响进行了探讨。采用H2-TPR、XRD等技术考察了CuO、NiO的还原状态,确定了最佳还原温度和最佳反应条件:在350℃的还原温度下,当反应温度为70℃、水为反应溶剂、n(H2O)∶n(C6H6)=40∶1、n(H2O2)∶n(C6H6)=5∶1时,苯转化率为36.2%,苯酚选择性为86.3%,苯酚收率为31.2%。

| Abstract: | The Cu-Ni/γ-Al2O3 catalyst was prepared via temperature-programmed reduction(H2-TPR).With this catalyst phenol can be synthesized by the benzene direct hydroxylation.Factors affecting this reaction such as reaction temperature,reaction solvent and ratio of reactants are discussed in this paper.The reductive states of CuO and NiO were characterized by H2-TPR and XRD.The best reduction temperature and the best reaction conditions were found under the reduction temperature of 350℃,water as reaction solvent,n(H2O)∶n(C6H6) of 40∶1 and n(H2O2)∶n(C6H6) of 5∶1.The conversion of benzene is 36.2%,the selectivity for phenol is 86.3% and the yield of phenol is 31.2%. |
