  • Patent number: 4292186
    Abstract: Fluid compositions containing a lubricant or liquid hydrocarbon fuel and a minor amount of a complex salt containing a 5- or 6-member ring are provided. These derivatives are made by complexing (1) the reaction product of an alcohol or an aminoalcohol with a succinic compound containing a long-chain hydrocarbon with (2) a metal salt. One such complex is one made by reacting a metal salt with the product of reaction between an alkylsuccinic acid or anhydride and said alcohol or aminoalcohol.
    Type: Grant
    Filed: July 3, 1980
    Date of Patent: September 29, 1981
    Assignee: Mobil Oil Corporation
    Inventors: Sheldon Chibnik, Ferdinand P. Otto, deceased, Helen F. Otto, executrix
  • Patent number: 4093614
    Abstract: Multiple metal complexes of nitrogen compounds are prepared by reacting in any desired order (1) an organic reactant, preferably an alkenylsuccinic acid or anhydride or a polyalkylphenol-aldehyde reaction mixture, or a halogenated polyolefin; (2) a polyamine, having one nitrogen atom reactive with the organic reactant and at least one additional nitrogen atom such as an ethylene polyamine and the imidazoline or imidazolidine derivative thereof; (3) and at least two metal compounds, one of which is a metal of Groups IB, IIB, IVA, IVB, VB, VIB, VIIB or VIII of the Periodic Table, capable of both forming a coordinated complex of the Werner type with the polyamine and also forming a complex with the second metal compound, and the said metal compound of metals of the above groups plus alkali and alkaline earth metals. The reactants may be reacted in any order, such as the above order, or the amine reactant may be precomplexed.

  • Patent number: 4028259
    Abstract: Phosphorus- and sulfur-containing metal salts are prepared by reacting a mixture comprising a metal oxide and a hydrocarbon in the presence of an oxidizing gas and then reacting this product with a phosphorus sulfide. The invention provides lubricant compositions containing the product.

    Inventors: Richard S. Herd, Ferdinand P. Otto
  • Patent number: 4011167
    Abstract: Lubricant compositions are provided containing a detergency improving amount of a metal complex prepared by (a) reacting a salt or oxide of a metal capable of forming a Werner complex with a compound containing at least one phenolic group to yield the metal salt of said compound; (b) reacting the resulting metal salt with a polyamine having the formula H.sub.2 N(C.sub.2 H.sub.4 NH).sub.x H where x is 1 to 5; and (c) reacting the resulting product with an alkenylsuccinic anhydride characterized by a molecular weight between about 400 and about 3,000.
