| abstract | IMPROVED EPOXIDATION PROCESS USING MOLYBDENUM CATALYSTS (D#80, 313-F) ABSTRACT OF THE DISCLOSURE A method of preparing an epoxide compound by re-acting an olefinically unsaturated compound with an organic hydroperoxide in the presence of a molybdenum catalyst is described. Selectivity to the epoxide is at least 96%, con-version of the hydroperoxide is at least 96%, yield to the epoxide is at least 94% and recovery of the catalyst is at least 90%. These excellent results are accomplished by using a molybdenum catalyst, such as a molybdenum complex of 2-ethyl-1-hexanol, at a concentration of 100 to 1000 ppm based on total charge, preferably 200 to 600 ppm. The mole ratio of olefinically unsaturated compound to organic hydro-peroxide is preferably in the range of 0.9:1 to 3.0:1 and the reaction temperature is preferably in the range of 50 to 180°C. It was further surprisingly discovered that the method of this invention works much better with t-butyl hydroperoxide as the organic hydroperoxide than with other hydroperoxides, such as cumene hydroperoxide. |
