A process is provided for the production of oxirane compounds by reaction of an olefin such as propylene with an organic hydroperoxide using a solid contact catalyst, characterized in that a series of separate reaction zones are used, each packed with epoxidation catalyst, and the concentration of hydroperoxide in the feed to each reaction zone is maintained below 8 wt %.
L'invention concerne un procédé permettant de produire des composés oxirane par réaction d'une oléfine, telle que le propylène, avec un hydroperoxyde organique au moyen d'un catalyseur de contact solide. Ce procédé est caractérisé en ce qu'une série de zones de réaction séparées sont utilisées, chacune de ces zones étant garnie d'un catalyseur d'époxydation, et en ce que la concentration d'hydroperoxyde dans la charge fournie à chaque zone de réaction est maintenue en-dessous de 8 % en poids.
