Abstract

1520523 Refining crude glyceride oils and waxes REWO CHEMISCHE FABRIK GmbH 19 Nov 1976 [21 Aug 1975] 34714/75 Heading C5C Crude glyceride oils and fats and crude waxes are purified by (a) intimately mixing the crude material with at least one organic polyol, each molecule of which contains 2 to 6 C atoms and 2 to 6 -OH groups, and an aqueous solution of at least one alkaline material, the amount of alkaline material(s) being at least that theroretically required to neutralize all the free fatty acid(s) present in the crude material, the weight ratio of polyol(s) to aqueous solution of alkaline material(s) in the mixture being not less than 1:2 and (b) allowing the product from (a) to separate into two layers and removing the top layer which contains the refined glyceride oil or fat or wax. The crude product may be coconut oil, palm kernel oil, ground nut-oil, sunflower seed oil, soyabean oil, olive oil, palm oil, cottonseed oil, safflower seed oil, sesame oil, maize oil, linseed oil, castor oil, rapeseed oil, jojoba oil, cocoa butter, sardine oil, herring oil, sperm oil, beef tallow, mutton tallow, bone grease, lard, spermaceti, wool grease, bees wax, carnauba wax and montana wax. The polyol is preferably glycerol and the alkali sodium hydroxide.
