Propylene oxide may be efficiently separated from contaminants present in the propylene/oxygen reaction effluent by adding a liquid boiling between 35*C and 100*C, which is not reactive with propylene oxide, to the reaction effluent and distilling propylene oxide from the resulting mixture. Propylene oxide is useful for the production of petroleum demulsifiers, surface active materials, urethane polyols and propylene glycols. |
