  • Use of microorganisms in combination with surface active agents to synergistically disperse oil slicks
    Patent number: 4146470
    Abstract: A method of preparation and application of a composition comprising specified microorganisms in combination with surfactants for a synergistic dispersal of oil slicks.
    Type: Grant
    Filed: July 22, 1977
    Date of Patent: March 27, 1979

  • Process for polymer lithiation in graft polymerization
    Patent number: 4078019
    Abstract: Graft polymers are prepared by contacting an anionically polymerizable monomer such as butadiene with a polymer-Liotertiary chelating polyamine complex such as polystyrene-Liotetramethyl ethanediamine.
    Type: Grant
    Filed: March 28, 1975
    Date of Patent: March 7, 1978

  • Surface active quaternary higher dialkyl phosphonium salts
    Patent number: 3998754
    Abstract: Higher dialkyl lower dialkyl phosphonium chloride salts, derived via quaternarization of phosphines with primary chlorides, have unexpected surfactant biocidal properties. Such quaternary salts are broad spectrum bactericides, fungicides and algicides, highly effective against gram negative organisms even in hard water. They are also useful as intermediates for the synthesis of quaternary phosphonium clays.

    Date of Patent: December 21, 1976
    Assignee: Exxon Research and Engineering Company
    Inventor: Alexis A. Oswald
  • Preparation of zerovalent phosphine substituted rhodium compounds and their use in the selective carbonylation of olefins
    Patent number: 3946082
    Abstract: A process for preparing oxygenated products comprising aldehydes, which have high normal to branched-chain isomer ratios. The process involves using particularly characterized rhodium-containing complex catalysts under a specific combination of carefully controlled reaction conditions. The product aldehydes as made above may be condensed and hydrogenated to form saturated aldehyde dimers thereof.

  • Chelated lithium aluminum compounds
    Patent number: 3933879
    Abstract: Chelated lithium aluminum compounds are prepared by mixing a lithium aluminum compound such as a lithium aluminum hydride with a chelating agent wherein the agent contains at least one nitrogen atom. The chelating agent is a tertiary polyamine or aminoether. The resultant chelate is used for a variety of processes such as separations, catalytic reactions, substitution reactions, reductions, electrochemical reactions, and also as an oil and fuel additive.
