Abstract

Formylated fatty compounds are prepared by reacting one or more fatty compounds with commercial formic acid containing 5 to 15 per cent by weight of water at a temperature between about 70 DEG C. and the normal boiling point of the reaction mixture in the presence of added strong mineral acid as catalyst, sufficient of the formic acid being present to allow its addition to a double bond of the fatty compound. The formylated products may be hydrolysed to the corresponding hydroxylated compounds. The starting materials are those defined in the parent Specification. Sulphuric acid is preferred as catalyst; perchloric acid may also be used. In examples: (1) oleic acid is refluxed with 90 per cent formic acid using sulphuric acid as catalyst and the resulting formoxy stearic acid is hydrolysed to monohydroxy-stearic acid; (4) oleic acid containing linoleic acid is formoxylated with 90 per cent formic acid in a number of experiments in which the catalytic effects of sulphuric acid and perchloric acid are compared.
