  • Patent number: 7009072
    Abstract: The invention is a process for producing alkaline earth metal salicylates for use as lubricant detergents and to compositions prepared by the process. The process comprises two steps. Step 1 is the alkylation of salicylic acid is conducted using C14 or greater linear ?-olefins to produce alkyl salicylic acids in commercially acceptable yields. The alkylation conditions produce predominately mono-substituted para alkyl salicylic acids that are oil soluble. Step 2 is the oil soluble acid is subsequently neutralized and overbased by carbonation of lime using CO2 in the presence of a promoter and a surfactant. The reaction mixture after overbasing is filtered and solvents are removed by distillation. Alternatively, alkyl salicylic acid can be reacted with a previously overbased alkaline earth sulfonate, e.g., calcium sulfonate, to produce alkaline earth salicylate salts comprising varying percentages of dispersed alkaline earth carbonate salts.
