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, 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. Lubricant, grease, fuel and aqueous compositions are provided detergency and anti-wear properties by the presence of these multiple complexes.
