  • Process for making an overbased, sulfurized salt of an alkylated hydroxyaromatic compound
    Patent number: 8580717
    Abstract: An overbased, sulfurized salt of at least one alkylated hydroxyaromatic compound, wherein the alkyl substituent of the hydroxyaromatic compound is a residue of at least one isomerized olefin having from about 15 to about 99 wt. % branching is disclosed. The overbased, sulfurized salt of at least one alkylated hydroxyaromatic compound is produced by the process comprising: (a) alkylating at least one hydroxyaromatic compound with at least one isomerized olefin having from about 15 to about 99 wt. % branching obtained by isomerizing at least one normal alpha olefin having from about 10 to about 40 carbon atoms, to provide at least one alkylated hydroxyaromatic compound; (b) neutralizing and sulfurizing the alkylated hydroxyaromatic compound in any order to provide at least one neutralized, sulfurized alkylated hydroxyaromatic compound; and (c) overbasing the at least one neutralized, sulfurized alkylated hydroxyaromatic compound.

  • Lubricating oil additive and lubricating oil composition containing same
    Patent number: 7943796
    Abstract: An overbased salt of an oligomerized alkylhydroxyaromatic compound is disclosed, wherein the alkyl group of the alkylhydroxyaromatic compound is derived from an olefin mixture comprising propylene oligomers having an initial boiling point of at least about 195° C. and a final boiling point of no more than about 325° C. as measured by ASTM D86. Also disclosed is a lubricating oil composition containing at least (a) a major amount of an oil of lubricating viscosity and (b) the overbased salt of the oligomerized alkylhydroxyaromatic compound.
