  • Circulating oil compositions
    Patent number: 6916766
    Abstract: A combination of an ashless dispersant comprising the reaction product of a succinic anhydride and a polyamine and an ashless rust inhibitor comprising a mixture of a succinic anhydride and a oxime substituted aromatic compound in a lubricant base stock along with a poly alkylene alcohol demulsifier provides a circulating oil composition having good demulsibility, deposit control and rust inhibition.
    Type: Grant
    Filed: January 28, 2003
    Date of Patent: July 12, 2005
    Assignee: ExxonMobil Research and Engineering Company
    Inventors: Kevin Buzdygon, Angela Stefana Galiano-Roth
  • High viscosity index wide-temperature functional fluid compositions and methods for their making and use
    Publication number: 20040154957
    Abstract: This invention relates to lubricants comprising base stocks and base oils that exhibit an unexpected combination of high viscosity index (130 or greater) and a ratio of measured-to-theoretical high-shear/low-temperature viscosity at −30 C or lower and the methods of making them. Specifically, the present invention relates to novel high viscosity index, low-viscosity lubricants usable as wide-temperature lubricants, for example hyrdraulic oils, comprising novel low-viscosity base stocks, with improved performance in low-temperature viscosity, and methods to produce them.
