Abstract:
A process for simultaneously producing an epoxide and a carboxylic acid from an olefin and an aldehyde, respectively, by co-oxidation over a catalyst in the presence of oxygen is described. The catalyst is made by precipitating silver oxide in the presence of copper(II) oxide, copper(II) borate or a mixture thereof. These novel heterogeneous catalysts provide higher selectivities to the epoxide than those obtainable with commercial catalysts.
