Abstract

1423636 Purifying vegetable oils PROCTER & GAMBLE CO 27 March 1974 [28 March 1973] 13566/74 Heading C5C A process for dewaxing a refined vegetable oil having less than 0À1 wt. per cent soap and less than 0À1 wt. per cent free fatty acid comprises (a) chilling the oil to below 60‹ F. (b) maintaining at below 60‹ F. for a period longer than 1 hour, (c) mixing the oil from step (b) with an alkaline solution containing more than 1 wt. per cent but less than 2À5 wt. per cent of NaOH or its stoichiometric equivalent of other alkali, (d) agitating the mixture from (c) for at least 1/2 hour to disperse the oil without forming an inseparable emulsion and (e) separating the resultant mixture to provide a wax-containing. aqueous phase and a dewaxed oil. The alternative alkali may be KOH, NaHCO 3 or aqueous. NH 3 .
