Abstract

The rearrangement of fatty acid radicles in a triglyceride mixture is effected by heating the mixture in the presence of not more than 10 per cent water and under a pressure at least as great as the vapour pressure of the mixture containing the water. Thus, a mixture of tristearin and free oleic acid is converted by such treatment to distearo-mono-olein, dioleomonostearin and free stearic acid. If any hydrolysis has taken place during the treatment, the pressure may be released, the water boiled off, and heating of the mixture continued to re-esterify free hydroxyl radicles. After the treatment, any free fatty acid may be removed by alkali-refining or by distillation or by esterification with glycerol. Triglyceride mixtures mentioned are coconut oil and tristearin, hydrogenated cottonseed oil and oleic acid, coconut oil and hydrogenated cottonseed oil and even a single fat such as coconut oil or palm oil.
