  • Patent number: 7572931
    Abstract: An improved process for production of dialkyldithiophosphinic acid including sulfurizing a purified dialkylphosphinic acid by: reacting a hypophosphorous acid or salt with a stoichiometric excess of an alpha olefin in the presence of a free radical initiator to form a reaction product comprising monoalkylphosphinic acid and dialkylphosphinic acid; adding sufficient aqueous base to the reaction product to i) form the salts of the phosphinic acids, and ii) establish an aqueous phase and an organic phase, wherein a monoalkylphosphinic acid solubilizes into an aqueous phase; separating the organic phase from the aqueous phase; acidifying the organic phase and removing the olefin from the organic phase; isolating the purified dialkylphosphinic acid product; and sulfurizing the purified dialkylphosphinic acid product to form a dialkydithiophosphinic acid.

  • Patent number: 7557072
    Abstract: Laundry detergent compositions that provide soil release benefits to all fabric comprising an organophosphorus soil release agents and optional non-cotton secondary soil release agents. The present invention further relates to a method for providing soil release benefits to cotton fabric by contacting cotton articles with a water soluble and/or dispersible organophosphorus material. The contacting can be during washing or by pretreating by applying the composition directly to stains or by presoaking the clothing in the composition prior to washing. The present invention further relates to providing soil release benefits to all fabric in the laundry wash load in the presence of a bleaching agent.
