| 摘 要： | 在以H2O2为氧化剂的环己烷液相温和氧化反应体系中,对空心钛硅分子筛(HTS)的催化性能进行了系统研究,详细考察了不同反应条件包括反应时间、反应温度、反应物料配比及催化剂用量对HTS催化性能的影响。结果表明,在温和反应条件下,HTS催化环己烷氧化反应中,环己酮和环己醇是主要产物;在优化的反应条件下,酮醇产率超过40%,酮/醇摩尔比大于2.0。

| Abstract: | The catalytic performance of hollow titanium silicalite (HTS) in cyclohexane oxidation with H2O2 as oxidant under mild conditions was investigated extensively. Different reaction conditions such as reaction temperature, reaction time, mole ratio of reactants, amounts of catalyst were examined. The results showed that cyclohexanone and cyclohexanol were the major products. Under optimized conditions, HTS showed excellent catalytic performance in cyclohexane mild oxidation reaction with KA oil yield above 40% and cyclohexanone to cyclohexanol molar ratio above 2.0. |
