A laboratory procedure was developed for hydrogenation of methyl esters of unsaturated fatty acids using decalin as a hydrogen‐transfer agent and 10% Pd/C as catalyst. The esters of 10‐undecenoic, oleic, elaidic, stearolic, linoleic, cycloaliphatic C 21 di‐, C 22 tri‐ and C 36 dicarboxylic acids, and a mixture of hydrnocarpic, chaulmoogric and gorlic acids were hydrogenated. Chromatographic and spectral analyses showed complete saturation. This procedure is simple, requiring no external source of hydrogen.
