Catalytic Epoxidation of Propylene Using Nitrous Oxide or Oxygen as Oxidant

Abstract

Abstract: K+-FeOx/SBA-15 modified by boron was efficient for propylene epox idation by N2O. The structure, environment of iron, and acid-base propert y of catalyst determined the reaction route probably by affecting the nature of a ctive oxygen species. K+-CuOx/SBA-15 or K+-CuOx-SiO 2 catalyst could catalyze propylene epoxidation by O2. CuI functioned as the active site for propylene epoxidation by O2.

Key words: nitrous oxide, oxygen, propylene, epoxidation, propylene oxide, iron-based catalyst, copper-based catalyst
