Process for the catalytic manufacture of saturated fatty monohydroxy acids or of derivatives of the latter
The subject of the invention is catalytic processes for manufacturing saturated fatty monohydroxy acids from saturated fatty monoepoxy acids which can be obtained by epoxidation of a non-ethylenic fatty acid. – The conversion of the saturated fatty monoepoxy acid to saturated fatty monohydroxy acid is brought about by liquid-phase hydrogenolysis in the presence of a nickel catalyst under a hydrogen pressure of between 5 bars and 150 bars, preferably of the order of 50 bars, at a temperature between 125 DEG C and 175 DEG C, preferably of the order of 150 DEG C. – One application is the production of saturated fatty monohydroxy acids from a plant oil in the hydrogenated or partially hydrogenated state, which is subjected to an epoxidation of the double bond and to a hydrogenolysis according to the invention.
