Abstract

Unsaturated palm oil fatty alcohols with an iodine number in the range from 65 to 85, which contain substantially unsaturated fatty alcohols and mixtures of saturated fatty alcohols of the formula (I):R1OH   (I)in which R1 is a saturated or unsaturated, linear or branched alkyl radical having 14 to 20 carbon atoms, are obtained by (a) fractionating palm oil fatty acid methyl esters into a mainly saturated C16-distillate and a mainly unsaturated C16/18-bottom product; and (b) hydrogenating the bottom product with retention of the double bonds to give the corresponding alcohols.
