Patent number: 6703520Abstract: The present invention provides a process for preparing a desired halogenated ester, which process comprises the steps of: (a) contacting (A) a substantially organic solvent free liquid mixture of (i) an alkanolate of the formula M—O—Z, wherein M is an alkali or alkaline earth metal, and Z is a linear, branched or cyclic alkyl group of 1 to 10 carbon atoms and (ii) a diester with (B) a halogenated ethylenically unsaturated olefin at a temperature of not more than 40° C. and with a mol ratio of halogenated ethylenically unsaturated olefin to alkanolate of not more than 1.1; (b) contacting an acid with a thus obtained reaction mixture thereby obtaining a mixture comprising the desired halogenated ester; and (c) recovering the halogenated ester from said reaction mixture.Type: GrantFiled: April 5, 2002Date of Patent: March 9, 2004Assignee: 3M Innovative Properties CompanyInventors: Klaus Hintzer, Egon Obermaier, Werner Schwertfeger

Patent number: 6664429Abstract: Branched, substantially unsaturated fatty alcohol polylglycol ethers 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) alkoxylating the branched, substantially unsaturated fatty alcohols. The fatty alcohol polylglycol ethers thus produced exhibit improved performance properties and greater oxidative stability than standard unsaturated fatty alcohol sulfates.Type: GrantFiled: July 22, 2002Date of Patent: December 16, 2003Assignee: Cognis Deutschland GmbH & Co. KGInventors: Norbert Huebner, Ansgar Behler, Alfred Westfechtel
