  • Patent number: 3941907
    Abstract: This invention relates to the use of salts of diamines having the formula ##EQU1## where R.sub.3 is alkylene having 2 to 4 carbon atoms and R.sub.1 and R.sub.2, together or separately, are hydrogen or alkyl having 1 to 8 carbon atoms, with an anion component having the formulaR--X.sup.-where X.sup.- is --SO.sub.3 .sup.- or --OCO.sub.3 .sup.- and R is a hydrocarbon radical having 6 to 26 carbon atoms which may be interrupted or substituted by groups containing heteroatoms, as parting agents for natural and synthetic elastomer compositions.
    Type: Grant
    Filed: November 28, 1973
    Date of Patent: March 2, 1976
    Assignee: Henkel & Cie G.m.b.H.
    Inventors: Gunter Klement, Horst Baumann, Eugen Scheidt
  • Patent number: 3936317
    Abstract: A dishwashing and cleansing agent composition for manual dishwashing based upon anionic surface-active surfactants consists essentially of (A) from 20% to 90% by weight of a higher sulfonate or sulfate of the group of the alkyl sulfonates, olefin sulfonates, .alpha.-sulfofatty acid alkyl esters, dialkyl sulfosuccinic esters, alkylbenzene sulfonates and alkyl sulfates, each having 8 to 20 carbon atoms in the hydrophobic moiety, and (B) from 10% to 80% by weight of a mono- or polyglycol ether sulfate of a higher 1,2-alkanediol having 10 to 22 carbon atoms; as well as a dishwashing concentrate containing this composition and a method of using this composition.
    Type: Grant

  • Patent number: 3931271
    Abstract: A process for the production of secondary alcohol ether sulfates which consists essentially of reacting adducts of secondary alkanols having from 6 to 22 carbon atoms adducted with 1 to 10 mols of an alkylene oxide selected from the group consisting of ethylene oxide and propylene oxide, said adduct having at least 1 mol of oxypropylene per mol of alcohol, with at least a molecular equivalent of a sulfating agent stronger than concentrated sulfuric acid at temperatures of from to and recovering said secondary alcohol ether sulfate.THE PRIOR ARTAt present secondary alcohols can be prepared from inexpensive raw materials, such as by oxidation of paraffins, substantially simpler than the preparation of primary alcohols. However, up to now the practical use of secondary alcohols is limited to non-ionic products prepared from them.
