Abstract

Vegetable and animal oils are purified by mixing with a dilute aqueous solution of an alkali together with a hydrotrope which is either urea or an alkali or alkaline earth metal salt of an aryl or alkyl aryl (e.g. C1-C8 alkyl) sulphonic acid, allowing the mixture to separate into an aqueous soap layer and an oily layer and removing the aqueous layer. The hydrotrope may be used in an amount of 1-3% wt. of the oil for every unit of acid value of the crude oil and the proportion of hydrotrope to water 40-60% wt. After removal of the aqueous layer the oil may be treated with a further quantity of hydrotrope in aqueous solution. Phosphatides present are extracted into the aqueous layer and may be recovered. In a preferred embodiment the aqueous layer is boiled with sufficient alkali to hydrolyse any glyceride oil and a mineral acid is added to obtain a fatty acid layer which is recovered. Salts may then be crystallized from the aqueous layer and the latter recycled.
