PROCESS FOR OXIDIZING FLUORINATED OLEFINS AND CATALYST USEFUL TO THE PURPOSE

摘要

A process for oxidizing fluorinated olefins to the corresponding epoxides by reacting a fluoroolefin with oxygen in a concentration, in the reaction mixture, ranging from 1 to 60% by volume, at a temperature up to 250.degree.C and in the presence of a catalyst consisting of porous silicon dioxide in a crystalline form, with a high purity degree and carrying metal oxides of the first transition series, or copper oxides or lanthanide oxides or mixtures thereof.
