To produce propylene oxide, a reaction liquid comprised of propylene, hydrogen peroxide and propylene oxide and a vapor purge stream is passed through the bed of solid catalyst at reaction conditions in each of a series of catalyst-packed reaction zones (2,14,22,30), the resulting mixture is separated in each zone into a vapor stream which passes to the next reaction zone and a reaction liquid stream (8,18,26), which is removed and cooled to remove exothermic heat of reaction. Some of the cooled liquid (11,20,28) is recycled to the zone from which it was removed and some (13,21,29) is passed to the next in the series of reaction zones. Also provided is a reactor for carrying out the reaction. <IMAGE> |
