Heterogeneous catalyst and process for producing oxirane compound with the catalyst

摘要

There is provided a process for producing oxirane compound comprising treating with hydrogen peroxide in the presence of either an olefin oxidation catalyst prepared from an organic compound or a polymer compound of formula (1) a tungstic acid compound, a phosphoric acid, hydrogen peroxide and a quaternary ammonium salt of formula (2) or (3) or an olefin oxidation catalyst prepared from an organic compound or a polymer compound of formula (1), a tungsten compound and a quaternary ammonium salt of formula (2) or (3). The process is useful especially industrially.
