A PROCESS FOR THE PRODUCTION OF OLEFIN OXIDES WHICH COMPRISES CONTACTING AN OLEFIN-CONTAINING GAS IN A FIRST REACTION ZONE WITH A REAGENT COMPRISING A METAL HALIDE SELECTED FROM THE GROUP CONSISTING OF COPPER, PLATINUM, PALLADIUM, IRIDIUM, ALUMINUM, ZINC, SILVER, MERCURY AND ANTIMONY AT A TEMPERATURE BETWEEN ABOUT 30* F. AND ABOUT 150* F. TO FROM AN OLEFIN COORDINATION COMPOUND, SEPARATING SAID OLEFIN COORDINATION COMPOUND FROM SAID GAS, OXIDIZING SAID OLEFIN COORDINATION COMPOUND IN A SECOND REACTION ZONE AT A TEMPERATURE BETWEEN ABOUT 400* F. AND ABOUT 100* F. TO CONVERT SAID OLEFIN COORDINATION COMPOUND TO ITS CORRESPONDING OLEFIN OXIDE AND TO FROM AN OXYGEN-CONTAINING COMPOUND OF THE METAL HALIDE, AND SEPARATING THE OLEFIN OXIDE THUS PRODUCED FROM SAID OXYGEN-CONTAINING COMPOUND OF THE METAL HALIDE.
