Saturated C 18‐ and C 20 ‐cyclic alcohols have been prepared by catalytic hydrogenation of methyl esters from cyclized linseed monomeric acids, purified saturated C 18 ‐cyclic acids, ethylene adduct of conjugated soybean fatty acids, and ethylene adduct of conjugated octadecadienoic acids. The cyclic alcohols have also been prepared from free acids of crude cyclic linseed, cyclic linseed monomeric, and ethylene adduct of 9,11, t,t ,‐octadecadienoic. Conversion of esters and acids was 88舑99% by hydroxyl determination; by gas‐liquid chromatographic analysis, almost quantitative Hydrogenations were carried out with 10%, by weight, copper chromite catalyst, an initial hydrogen pressure of 2,100 psi, and a temperature of 280C for 3舑5 hr. Preliminary evaluations indicate that saturated C 18‐ and C 20 ‐cyclic alcohols have a potential use in cosmetic formulations.
