  • Process for making unsaturated coconut and/or palm nut fatty alcohols
    Patent number: 7408087
    Abstract: 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): R1OH ??(I) in which R1 is 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 C16-C18 portions, fractionating the C16-C18 fatty 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.

  • Unsaturated palm oil fatty alcohols
    Patent number: 7169959
    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.

  • Unsaturated fatty compounds with improved low-temperature behavior
    Patent number: 5917097
    Abstract: A process for producing unsaturated fatty compounds having improved low-temperature properties bya) splitting lauric oils into fatty acids and glycerol,b) subjecting the fatty acids to fractional crystallization to obtain a fraction of unsaturated fatty acids, andc) hydrogenating the unsaturated fatty acids, optionally after converting the unsaturated fatty acids into their lower alkyl esters, to form unsaturated fatty alcohols having an iodine value of from about 85 to about 100.
