| Abstract: | The epoxidation of allyl alcohol(AAL) with hydrogen peroxide to glycidol(GLY) over Ti-MWW catalyst using H_2O as solvent is one of the most promising processes in industry for its mild reaction condition,high yield and friendly to environment.The influence of reaction temperature and the ratio of AAL to H_2O_2 on this reaction has been investigated.Simultaneously,the effects of temperature and pH on the secondary reaction have been analyzed.Based on the above,the possible reaction mechanism and kinetics models of main and secondary reactions are obtained.Comparing of calculated data with experimental results indicates the availability of the kinetics models. |
