Abstract RU 2430905 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing saturated carboxylic acids and derivatives thereof, comprising the following steps: (a) reacting an unsaturated fatty acid derivative, in which the carboxyl group is prepared for reaction to form a modified carboxyl group so as to prevent or, in any case, minimise any possible reactions of the carboxyl group modified that way, when realising the method, with an oxidising compound in the presence of a catalyst capable of catalysing oxidation of the ethylene double bond of the unsaturated fatty acid derivative to obtain an intermediate product of a vicinal diol reaction; and (b) reaction of said intermediate compound with oxygen or an oxygen-containing compound in the presence of a catalyst which is capable of catalysing oxidation of hydroxyl groups of the vicinal diol to carboxyl groups, characterised by that both steps (a) and (b) are realised in the absence of an added organic solvent and that, the ratio of water to diol at step (b) is less than 1:1.

EFFECT: improved method.
