  • Patent number: 6730768
    Abstract: A method for preparing a polyol useful in the formation of an isocyanate casting resin or coating composition is presented involving the reaction of an essentially C18 fatty acid mixture with a monofunctional alcohol to form a fatty acid ester mixture, forming a epoxidized fatty acid ester mixture from the fatty acid ester mixture, and reacting the epoxidized mixture with an aliphatic alcohol to form a polyol. The polyol can be further reacted with an isocyanate to form a casting resin or coating composition. The fatty acid mixture contains at least 80 percent oleic acid. Polyols prepared by this method provide good color quality and improved color stability during storage when used in the production of isocyanate casting resins and coating compositions.

  • Patent number: 6723867
    Abstract: Branched, substantially unsaturated fatty alcohol sulfates are produced by a process which comprises the steps of: (a) dimerizing unsaturated C16-22 fatty acid to form a dimer fraction and a monomer fraction comprised of branched, substantially unsaturated fatty acids and straight chain saturated fatty acids, (b) removing the monomer fraction from the dimerization step, (c) converting the branched, substantially unsaturated fatty acids from step (b) into the corresponding fatty acid methyl esters, (d) hydrogenating the branched, substantially unsaturated fatty acid methyl esters with the double bonds intact to form the corresponding branched, substantially unsaturated fatty alcohols and (e) sulfating and neutralizing the branched, substantially unsaturated fatty alcohols.

  • Patent number: 6716799
    Abstract: The invention relates to the use of linear and/or branched fatty alcohols containing at least 12 carbon atoms in the molecule and/or to the use of mixtures of such fatty alcohols with carboxylic acid esters as a lubricating additive in water-based drilling fluids for their use in geological exploration by drilling. The fatty-alcohol-based lubricants or lubricant systems are particularly suitable for use in water-based alkali metal silicate drilling muds which are known to be distinguished by comparatively high pH values. The additives according to the invention combine their lubricating effect with a foam-suppressing effect, i.e. prevent unwanted foaming.
