PURIFICATION OF PROPYLENE OXIDE BY LIQUID EXTRACTION (Docket No. 80,919-F) ABSTRACT OF THE DISCLOSURE Purified propylene oxide is recovered from an impure propylene oxide feedstock contaminated with more than 50 ppm of six carbon atom hydrocarbon impurities by a solvent extraction process wherein: an impure propylene oxide feedstock is charged to a liquid/liquid extraction zone and contacted therein with an extractant consisting essentially of water and a paraf- finic hydrocarbon containing 8 to 10 carbon atoms, and resolved therein into a raffinate consisting essentially of an aqueous solution of propylene oxide and into an extract comprising the paraffinic hydrocarbon and the 6 carbon atom impurities initially present in the propylene oxide feedstock.
