  • Patent number: 4153564
    Abstract: Compounds that act as emulsifiers, detergents and antioxidants when added to a lubricant or a fuel are prepared from (1) an alkenylsuccinic anhydride or acid and an aniline-aldehyde resin or (2) the product of (1) and an aromatic triazole, e.g. benzotriazole, and aldehyde. Also included are lubricant compositions containing the compounds.
    Type: Grant
    Filed: April 24, 1978
    Date of Patent: May 8, 1979
    Assignee: Mobil Oil Corporation
    Inventor: Sheldon Chibnik
  • 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.
    Type: Grant

  • Patent number: 4083699
    Abstract: The detergency properties of a fuel or a lubricant are improved by adding thereto a Mannich base product prepared by reacting a high molecular weight alkyl substituted hydroxyaromatic compound, a polyoxyethylene polyamine and an aldehyde.

  • 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.
