Propylene epoxidation by H2O2 (30 % aqueous) as oxidant was studied in a semi-batch reactor using TS-1 catalyst : Effects of reaction temperature, time, pressure, solvent, catalyst and H2O2 concentration on H2O2 conversion(limiting reagent) and product distribution were investigated. Potential inhibition by propylene oxide on the epoxidation rate was also examined. Ti-MCM-22 with MWW zeolytic structure was found to exhibit better performance than TS-1 with MFI structure, provie that a proper choice of solvent(acetonitrile) is made. |
