摘要
研究了以甲醇作为溶剂时 ,钛硅分子筛 (TS 1 )催化丙烯H2 O2 环氧化反应的过程 ,分析了丙烯压力、温度等因素对反应的影响 ,发现TS 1催化剂不但对环氧丙烷的开环醚化有催化作用 ,而且对H2 O2 分解有促进作用 ,在此基础上确定了主、副反应动力学参数 ,为该工艺的工业化提供了依据 .
The epoxidation of propylene with hydrogen peroxide in methanol is studied under mild conditions over titanium silicalite catalyst (TS*.1). Analyzed are the influence of temperature and pressure and other factors on reaction. It is founded that TS*.1 has catalysis not only on propylene epoxidation, but also on PO etherification and hydrogen peroxide decomposition. Parameters for primary and side reaction are determined for the kinetics models. The results provide basis for reactor and process design.
