  • Graphite dispersion
    Patent number: 4434064
    Abstract: Disclosed is a method for stabilizing a graphite in-oil-dispersion by means of a fracture induced oxidation of graphite particles to produce a composition suitable as a constituent of a lubricating oil composition.The oxygen content of the graphite particles is at least about 1% by weight of the total weight of the ground graphite particle including oxygen.
    Type: Grant
    Filed: May 4, 1981
    Date of Patent: February 28, 1984
    Assignee: Atlantic Richfield Company
    Inventors: Tai S. Chao, Aubrey C. Smith, Jr., Frederic D. Smies
  • Graphite dispersion
    Patent number: 4372861
    Abstract: Disclosed is a method for providing a shear stable graphite-in-oil dispersion by means of selected non-polymeric dispersing agents. The oxygen content of the graphite particles is at least about 1% by weight of the total weight of the ground graphite particle including oxygen.
    Type: Grant
    Filed: May 4, 1981

  • Stabilization of hydrocracked oils with aliphatic amine components
    Patent number: 4264461
    Abstract: Hydrocracked lubricating oils are effectively stabilized against deterioration caused by light by the inclusion of at least one of certain substantially aliphatic amine components. Such substantially aliphatic amine components provide outstanding inhibition relative to aromatic amine components.
