  • Method of preparing overbased magnesium sulfonates
    Patent number: 4201682
    Abstract: Over-based oil-soluble magnesium sulfonate compositions are formed by one-step carbonation of a reactant mixture containing magnesium hydroxide formed in situ.
    Type: Grant
    Filed: October 24, 1975
    Date of Patent: May 6, 1980
    Assignee: Standard Oil Company (Indiana)
    Inventors: Albert R. Sabol, Dennis G. Petrille, Edward W. Heffern
  • Gelled hydrocarbon fuels
    Patent number: 4166723
    Abstract: Gelled fuel compositions having improved burning characteristics comprise a normally liquid petroleum fuel boiling in the range of about 100.degree.-600.degree. F.; a gelling agent; and about 0.5-20 volume percent acetic anhydride.
    Type: Grant
    Filed: July 30, 1965
    Date of Patent: September 4, 1979
    Assignee: Standard Oil Company (Indiana)
    Inventor: Edward F. Steigelmann
  • Method of preparing overbased barium sulfonates
    Patent number: 3959164
    Abstract: Over-based oil-soluble barium alkenyl sulfonates wherein the alkenyl moiety is a propene or butene polymer having a number average molecular weight of about 250-500 are obtained by heating a mixture of ammonium alkenyl sulfonates, a precarbonated mixture of barium oxide in methanol, barium oxide and water in the range of about 160-190.degree.F for time sufficient to convert the ammonium sulfonate to barium sulfonate.
    Type: Grant
    Filed: December 20, 1972
    Date of Patent: May 25, 1976
    Assignee: Standard Oil Company
    Inventor: Albert R. Sabol
  • Preparation of alkenyl sulfonates
    Patent number: 3954849
    Abstract: Treatment of oil-soluble viscous liquid propene or butene polymers having a number average molecular weight of about 250-500 with gaseous sulfur trioxide in falling-film or static reactors yields acidic sulfonation products comprising alkenyl sulfonic acids and polymer sultones. Two-stage neutralization of the sulfonation product with ammonia or sodium hydroxide reduces the sultone content and increases the sulfonate content in the neutralized product.
    Type: Grant
    Filed: December 5, 1974
    Date of Patent: May 4, 1976
    Assignee: Standard Oil Company
    Inventors: Robert E. Karll, Dennis G. Petrille, Edward W. Heffern
  • Process for introducing zinc micronutrients into liquid fertilizers
    Patent number: 3951639
    Abstract: Zinc particulate compositions precoated with aliphatic amines, salts of such amines or mixtures thereof, when added to phosphate-containing liquid fertilizers, avoid lumping and caking which otherwise occurs when uncoated zinc compositions are added to such liquid fertilizers.
    Type: Grant
    Filed: January 28, 1974
    Date of Patent: April 20, 1976
    Assignee: Standard Oil Company
    Inventor: Richard J. Windgassen
  • Olefin sulfonates
    Patent number: 3950401
    Abstract: Viscous liquid propene or butene polymers having number average molecular weights of about 250-500 are converted to the corresponding oil-soluble ammonium alkenyl sulfonates by treatment of the polymer with gaseous sulfur trioxide in a falling-film reactor, separation of the oil-soluble polymer sulfonic acids and oil-soluble polymer sultones from the sulfonation product mixture, and neutralization of the sulfonic acids and sultones with anhydrous ammonia.
    Type: Grant
    Filed: November 18, 1974
    Date of Patent: April 13, 1976
    Assignee: Standard Oil Company
    Inventors: Dennis G. Petrille, Robert E. Karll
