  • Patent number: 4765875
    Abstract: This invention relates to sulfonated lubricating agents for leather and furs. More specifically, this invention relates to a process for the production of sulfonated lubricating agent for leather and tanned furs consisting of the steps of:(a) sulfochlorinating higher fatty acids or esters of higher fatty acids having chain lengths of from 8 to 24 carbon atoms with chlorine and SO.sub.2 at a temperature of from about 20.degree. to 90.degree. C. under UV-radiation for a time sufficient to obtain a compound having a chlorine content of from about 5 to 30 percent by weight and a content of --SO.sub.2 Cl groups of from about 1 to 20 percent by weight, the ratio of chlorine atoms to --SO.sub.2 Cl groups being from about 0.7:1 to 70:1; and(b) forming a water-emulsifiable alkali metal, ammonium, or lower alkyl-ammonium salt of the compound produced in step (a).
    Type: Grant
    Filed: August 29, 1983
    Date of Patent: August 23, 1988
    Assignee: Henkel Kommanditgesellschaft auf Aktien

  • Patent number: 4309176
    Abstract: This invention is directed to an improved process of oiling and impregnating leather or pelts in which the leather or pelts are contacted with one or more oiling substances in an aqueous liquor, wherein the improvement comprises using an alkylolamide ether sulfate or phosphate of fatty acids of the formulaR--CO--NH--(CH.sub.2).sub.n --O--(CH.sub.2 --CH.sub.2 --O).sub.m XwhereinR represents an aliphatic radical of from about 13 to 19 carbon atoms;n is a number of from 2 to 4;m is a number of from 1 to 4;X is --SO.sub.3 Y or --PO(OY).sub.2 ; andY is a sodium, potassium, or ammonium anionas an oiling substance in the liquor bath.

  • Patent number: 3988247
    Abstract: Process and agent for fatting or lubrication of leather and furs based on the salts of sulfonated chlorinated products of higher fatty acids or of esters of higher fatty acids, said fatty acids having from 8 to 24 carbon atoms, especially natural fats and oils or tallow fatty acid methyl ester, having a chlorine content of 20% to 45% by weight and essentially free of olefinic double bonds and having an SO.sub.3 content of from 40 to 150 mol percent based on the chlorinated product, which agent and the leather and furs so treated are extraordinarily resistant to the effect of light, to oxidation and to acids.

  • Patent number: 3957426
    Abstract: Fatty acid ester mixtures liquid at low temperatures comprising (A) alkylene oxide adducts to train-oil fatty acids, or mixtures, esterified with unsaturated fatty acids, or mixtures, which are substantially free of any polyunsaturated train-oil fatty acids; or (B) alkylene oxide adducts to unsaturated fatty acids, or mixtures, which are substantially free of any polyunsaturated train-oil fatty acids, esterified with train-oil fatty acids, or mixtures; as well as compositions for using and the processes of preparing and using these esters.
