ABSTRACT:
A method for the preparation of an epoxide by reacting an olefin having 3 or more carbon atoms with a hydroperoxide in the presence of a catalyst. The catalyst includes molybdenum and/or tungsten and an inorganic metal phosphate and/or arsenate wherein at least the inorganic metal phosphate and/or arsenate is substantially insoluble in the olefin hydroperoxide reaction mixture. The metal portion of the inorganic metal phosphate and/or arsenate is one or more metals selected from the group consisting of the metals found in Groups I to III, VIIb and VIII, of the Periodic Table of Elements. Preferred metals include aluminum, iron, zinc and mixtures of these metals.
