Unsaturated coconut and/or palm nut fatty alcohols having an iodine number in the range from 65 to 85, which essentially comprise unsaturated fatty alcohols and mixtures of saturated fatty alcohols of the formula (I):ROH &#x2003;&#x2003;(I)in which Ris a saturated or unsaturated, linear or branched alkyl radical having 12 to 20 carbon atoms, obtainable by fractionating coconut and/or palm nut fatty acid methyl esters to obtain a fraction containing predominantly C-Cportions, fractionating the C-Cfatty acid methyl ester fraction into a predominantly saturated distillate and a predominantly unsaturated bottom product, and hydrogenating the bottom product with retention of the double bonds to give the corresponding alcohols; are disclosed.

Process for making unsaturated coconut and/or palm nut fatty alcohols

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):ROH &#x2003;&#x2003;(I)in which Ris 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 C-distillate and a mainly unsaturated C-bottom product; and (b) hydrogenating the bottom product with retention of the double bonds to give the corresponding alcohols.
