  • Low temperature performance lubricating oil detergents and method of making the same
    Patent number: 8993499
    Abstract: A carboxylate detergent prepared by the process comprising (a) alkylating a hydroxyaromatic compound with at least one normal alpha olefin having from about 12 to about 30 carbon atoms per molecule that has been isomerized to obtain an isomerized alpha olefin having 15-98 wt % branching and a residual alpha olefin content of between from about 0.1 to about 30 wt %, thereby producing an alkylated hydroxyaromatic compound; (b) neutralizing the resulting alkylated hydroxyaromatic compound with an alkali metal base; (c) carbonating the alkali metal salt from step (b) with carbon dioxide; (d) acidifying the salt produced in step (c); and (e) overbasing the resulting alkylated hydroxyaromatic carboxylic acid.
