Abstract: THIS INVENTION RELATES TO A PROCESS FOR PREPARING PROPYLENE GLYCOL WHICH MEETS BOTH U.S.P. AND FOOD GRADE STANDARDS. THE PROCESS COMPRISES TREATING A CRUDE PROPYLENE OXIDE WITH AN AQUEOUS BASE, PHASE SEPARATING, HYDROLYZING THE SEPARATED PROPYLENE OXIDE FRACTION TO FORM PROPYLENE GLYCOL AND PASSING SAID PROPYLENE GLYCOL INTO A DISTILLATION ZONE, FRACTIONALLY DISTILLING THE PROPYLENE GLYCOL, SEPARATING PURE MONO PROPYLENE GLYCOL AS A LIQUID STREAM AT AN INTERMEDIATE POINT IN SAID ZONE FROM IMPURITIES WHICH BOIL HIGHER AND LOWER THAN THE PROPYLENE GLYCOL.
