  • Base oil for shear stable multi-viscosity lubricants and lubricants therefrom
    Patent number: 5436379
    Abstract: Fully synthetic lubricating base oil compositions are formulated from blends of 50-97 wt % of synthetic hydrocarbons and 3-30 wt % isobutylene oligomers. The lubricating base oil composition have constant viscosity indexes which are higher than those of the components used to form the compositions. The synthetic hydrocarbon and isobutylene oligomers are combinable in various amounts with conventional additives to form multi-grade engine lubricants, which are shear stable.
    Type: Grant

  • Preparation of alkylated cyclopentadienes
    Patent number: 5210351
    Abstract: Cyclopentadienes are alkylated by initially reacting primary or secondary alcohols at elevated temperatures in the presence of an alkali metal hydroxide with removal of water to form dimers of said primary or secondary alcohols, and thereafter reacting said alcohol dimers with a cyclopentadiene to alkylate said cyclopentadiene.

  • Substituted cyclopentadienes, methods of manufacture and uses
    Patent number: 5144095
    Abstract: Tertiary alkyl substituted cyclopentadienes are prepared by reaction of cyclopentadiene with a stoichiometric excess of a tertiary alkyl halide under phase transfer conditions. The tertiary-alkyl substituted cyclopentadienes are useful as synthetic lubricants.

  • Lubricants comprising novel cyclopentanes, cyclopentadienes, cyclopentenes, and mixtures thereof and methods of manufacture
    Patent number: 5012022
    Abstract: Hydrocarbyl substituted cyclopentadienes, cyclopentenes, and cyclopentanes and synthetic lubricating compositions. The preferred structures contain 1 to 6 alkyl groups which have 4 to 36 carbon atoms and may have different and varying carbon chain structures. The cyclopentenes and cyclopentanes are prepared by hydrogenation from the corresponding cyclopentadiene intermediates. The cyclopentadienes are prepared by reaction with hydrocarbylating agents or alcohols. Mixtures are also disclosed.

  • Process for removing sulfur from coal
    Patent number: 4497636
    Abstract: A process for the removal of divalent organic and inorganic sulfur compounds from coal and other carbonaceous material. A slurry of pulverized carbonaceous material is contacted with an electrophilic oxidant which selectively oxidizes the divalent organic and inorganic compounds to trivalent and tetravalent compounds. The carbonaceous material is then contacted with a molten caustic which dissolves the oxidized sulfur compounds away from the hydrocarbon matrix.
