  • Process for preparing white oil containing a high proportion of isoparaffins
    Patent number: 5453176
    Abstract: A process is disclosed for producing an isoparaffin white oil by contacting a refinery stream, in the presence of hydrogen, with a catalyst comprising an intermediate pore size silicoaluminophosphate molecular sieve and a hydrogenation component to form a dewaxed oil product. The dewaxed oil product is then contacted with a hydrogenation catalyst to produce a hydrogenated oil product which is then treated to remove aromatics to produce an isoparaffin white oil.
    Type: Grant

    Date of Patent: September 26, 1995
    Inventors: Bruce A. Narloch, Michael A. Shippey, Malcolm W. Wilson
  • Lubricating oil compositions containing a combination of a modified succinimide and a Group II metal overbased sulfurized alkylphenol
    Patent number: 4927551
    Abstract: Lubricating oil compositions containing a combination of a polyamino alkenyl or alkyl succinimide modified to contain carbamate functionalities and a Group II metal overbased sulfurized alkylphenol unexpectedly possess little, if any, adverse compatability effects on deposits in diesel engines as compared to lubricating oil compositions containing a combination of an unmodified polyamino alkenyl or alkyl succinimides and a Group II metal overbased sulfurized alkylphenol.
    Type: Grant
    Filed: April 14, 1989
    Date of Patent: May 22, 1990
    Assignee: Chevron Research Company
    Inventors: Timothy R. Erdman, Michael A. Shippey, Robert H. Wollenberg
  • Overbased ortho-carboxy phenylphenone lubricating oil additives
    Patent number: 4550197
    Abstract: Disclosed are overbased ortho-carboxy phenylphenones. The overbased ortho-carboxy phenylphenones provide detergency for the lubricating oil additionally providing an alkaline reserve.
    Type: Grant
    Filed: September 28, 1984
    Date of Patent: October 29, 1985
    Assignee: Chevron Research Company
    Inventor: Michael A. Shippey
  • Ortho-carboxy phenylphenone lubricating oil additives
    Patent number: 4548723
    Abstract: Disclosed are lubricating oil compositions containing the neutral and overbased ortho-carboxy phenylphenones. The neutral ortho-carboxy phenylphenones provide detergency for the lubricating oil; whereas, the overbased derivatives additionally provide an alkaline reserve.
    Type: Grant

  • Oil-soluble metal thiolate-succinimide complexes
    Patent number: 4397749
    Abstract: Oil-insoluble metal thiolates prepared by reacting an acyloin, phosphorus pentasulfide and a heavy metal salt are rendered oil soluble when combined with alkenyl or alkyl mono- or bis-succinimides. The complexes are effective as anti-oxidants and anti-wear inhibitors in lubricating oils.

    Date of Patent: August 9, 1983
    Assignee: Chevron Research Company
    Inventor: Michael A. Shippey
  • Process for synthesizing silylated polyalkenamers
    Patent number: 4396750
    Abstract: A process for polymerizing cycloalkenes into polyalkenamers is described wherein trisubstituted silyl groups are attached to the cycloalkenes. The silyl groups thus attached do not act as a poison to the polymerization process. Trimethylsilyl group can be substituted by other desired functional groups after the polymerization.
