CA 2445342

A process for producing propylene oxide which comprises a step of reacting propylene with cumene hydroperoxide in the presence of a catalyst, to form propylene oxide, and a step of subjecting the reaction product of the above reaction step to a distillation and recovering unreacted propylene from the top of a distillation column, wherein the bottom temperature of the distillation column is set at 200 ~ C or lower.

Un procédé de fabrication d'oxyde de propylène consiste à faire réagir du propylène avec de l'hydroperoxyde de cumène en présence d'un catalyseur, pour former de l'oxyde de propylène, et soumettre l'oxyde de réaction de l'étape précédente à la distillation puis à récupérer le propylène n'ayant pas réagi depuis le haut de la colonne de distillation, la température du fond de la colonne de distillation étant de 200 ·C ou moins.
