PROCESS FOR THE PREPARATION OF OLEFIN OXIDES WHICH COMPRISES OXIDIZING AN EPOXIDIZABLE OLEFINICALLY UNSATURATED HYDROCARBON COMPOUND HAVING UP TO 18 CARBON ATOMS, WITH MOLECULAR OXYGEN AT A TEMPERATURE WITHIN THE RANGE OF FROM 50* TO 400*C. AND A PRESSURE WITHIN THE RANGE OF FROM 0.2 TO 350 ATMOSPHERES IN A LIQUID REACTION MEDIUM CONSISTING ESSENTIALLY OF A MAJOR AMOUNT OF A MATERIAL SELECTED FROM THE GROUP CONSISING OF UNSATURATED ALIPHATIC, ALICYCLIC AND AROMATIC NITRILES AND MIXTURES THEREOF, SAID ALIPHATIC NITRILES HAVING FROM 1 TO 18 CARBON ATOMS IN THE NON-NITRILIC PORTION OF THE MOLECULE AND SAID ALICYCLIC AND AROMATIC NITRILES HAVING NOO MORE THAN 6 CARBON ATOMS IN THE RING AND HAVING NO SUBSTITUENTS OTHER THAN ALKYL GROUPS HAVING UP TO 6 CARBON ATOMS WHEN SUBSTITUTED.
