  • Middle distillate hydrocarbon foam control agents from alkymethylsiloxanes
    Patent number: 5435811
    Abstract: Organosilicone materials that are "density-matched" to the hydrocarbon medium also act as defoamers in hydrocarbon fuel, specifically as described herein for diesel fuel. Specifically these new defoamers can be described as alkylmethylsiloxanes. They have the characteristics of being slightly soluble or insoluble in water and hydrocarbon fuels. By changing the solvent and the method of dispersion, different particle size distributions are obtained.
    Type: Grant
    Filed: November 19, 1993
    Date of Patent: July 25, 1995
    Assignee: Dow Corning Corporation
    Inventors: Kenneth C. Fey, Christopher S. Combs
  • Middle distillate hydrocarbon foam control agents from cross-linked organopolysiloxane-polyoxyalkyenes
    Patent number: 5397367
    Abstract: Organosilicone materials that are "density-matched" to the hydrocarbon medium also act as defoamers in hydrocarbon fuel, specifically as described herein for diesel fuel. Specifically these new defoamers can be described as cross-linked organopolysiloxane-polyoxyalkylenes. They have the characteristics of being slightly soluble or insoluble in water and hydrocarbon fuels. By changing the solvent and the method of dispersion, different particle size distributions are obtained.
