    Abstract: This invention relates to novel overbased and neutral oil soluble metal dialkaryl hydrocarbon sulfonate compositions possessing low viscosity and outstanding rust inhibiting as well as water demulsification properties. Also, this invention relates to oil soluble metal dialkaryl sulfonate compounds in which the alkyl substituents contain from eight to 18 carbon atoms and are bonded to the aryl nucleus through a secondary carbon atom. In one aspect, the present invention concerns metal dialkaryl sulfonate compositions containing at least 20 weight percent metal dialkaryl sulfonate compounds in which the alkyl substituents are straight chain and contain from about eight to about 18 carbsn atoms, the aryl moiety being selected from the group consisting of benzene, toluene, xylene, naphthalene and mixtures thereof. In another aspect, the present invention concerns oil soluble metal sulfonate compositions containing metal dialkaryl sulfonate compounds in which one of the alkyl substituents is a straight chain group and the other is a branched chain group, the aryl moiety being selected from the group consisting of benzene, toluene, xylene, naphthalene, and mixtures thereof. In still another aspect, this invention concerns oil soluble metal hydrocarbon sulfonate compositions containing a major amount of metal dialkaryl sulfonate compounds in which the alkyl substituents are straight chain and contain from about eight to about 18 carbon atoms, the aryl moiety being selected from the group consisting of benzene, toluene and xylene, and a minor amount of tetrahydronaphthalene sulfonate compounds, said conpositions being derived from hydrocarbon compositions prepared by the disproportionation of mono-n-alkaryl compounds using aluminum chloride and/or aluminum bromide as the catalyst.

    Abstract: An overbased dispersion useful as a lubricating oil additive is prepared by adding a metal alkoxide-carbonate complex to an alcohol or alcohol-aromatic solution of a metal free, oil soluble, neutral or basic dispersing agent containing an acylated nitrogen atom. The dispersing agent is preferably an amide, imide or ester derived from the reaction of a high molecular weight alkenyl carboxylic acid or acid anhydride with an organic nitrogen-containing compound having at least one amino group or hydroxyl group. Concurrently with, or following, addition of the alkoxide-carbonate complex, the complex is hydrolyzed to yield a dispersion of fine particles of metal carbonate. The solvents are then stripped from the dispersion to form a bright, clear composition having a base number of from about 50 to about 250 and useful as an ashless detergent-dispersant additive to lubricating oils.
