Epoxidation of propene to propene oxide with O_2 and H_2 catalyzed by Eu centre dot Ti-Catalytic System

摘要

One step synthesis of propene oxide from propene, O_2 and H_2 was performed by Eu-catalytic system at atmosperic pressure and 40 deg C. The catalytic activity of Eu-catalyst was improved by addition of Ti(acac)_2 co-catalyst and various supported precious metal co-catalyst. Most active combination of each elements for the epoxidation was EuCl_3, TiO(acac)_2 and Rh/TiO_2.
