A process for preparing an olefin oxide by heterogeneously catalyzed gas-phase epoxidation of an olefin by means of a peroxidic compound comprising the step of carrying out the gas-phase epoxidation at temperatures above 100° C. using a reactor which has at least one reaction space having at least one dimension of less than 10 mm, wherein the surface of the reaction space has a layer comprising aluminum oxide, zirconium oxide, tantalum oxide, silicon dioxide, tin oxide, glass and/or enamel and wherein the reaction space contains catalyst.
A process for preparing a peroxidic compound by heterogeneously catalyzed reaction in the gas phase comprising the step of carrying out the reaction by reaction of a precursor of the peroxidic compound with oxygen and/or an oxygen-containing compound to form the peroxidic compound at temperatures above 100° C. using a reactor which has at least one reaction space having at least one dimension of less than 10 mm, wherein the surface of the reaction space has a layer comprising aluminum oxide, zirconium oxide, tantalum oxide, silicon dioxide, tin oxide, glass and/or enamel and wherein the reaction space may contain catalyst.
