叔丁醇溶剂中TS-1催化丙烯环氧化的动力学研究

The intrinsic kinetics of propylene epoxidation with H2O2 over TS-1 in t-butyl alcohol/water system was investigated. The reaction was carried out at T=303.15 K～323.15 K, p=0.3 MPa～0.6 Mpa. Based on the proposed reaction mechanism and adsorption characteristics, the kinetic model was established as follows:based on the experimental data, the model parameters were estimated. The results showed that the Eley-Rideal model could fit precisely with the experimental data, and the reaction takes place between H2O2 adsorbed on Ti active sites and propylene in free state.
