ABSTRACT:
A process for the production of an olefin oxide, which process comprises reacting a feed comprising an olefin and oxygen in the presence of a silver-containing catalyst, wherein before the catalyst has reached an advanced stage of ageing the reaction temperature is above 255° C. and the olefin content of the feed is above 25 mole-%, relative to the total feed.
