ABSTRACT:
A liquid phase continuous process for producing propylene oxide comprising oxidizing propylene with a molecular oxygen-containing gas in a solvent which is (a) water-insoluble and (b) as immiscible with organic carboxylic acids as possible; condensing the gaseous reaction products; adding water to the condensed reaction products to dissolve any undissolved acids contained therein; separating the aqueous phase from the resulting two-phase (aqueous and organic) system; recycling the organic phase to the reaction; and removing from the reaction a liquid containing propylene oxide and recovering the propylene oxide therefrom.
