ABSTRACT:
An additive useful in a marine lubricating oil is produced by reacting at elevated temperatures in the presence of at least one light hydrocarbon solvent and promoter: an alkyl oxy aromatic sulfonate; an alkaline earth metal base; carbon dioxide; and an acid component, such as carboxylic acid, an acid anhydride, an acid choride, or ester thereof. If the alkyl oxy aromatic sulfonate is in the acidic form, then the acid component is in the acidic form. If the alkyl oxy aromatic sulfonate is in the neutralized form, then the acid component is in the neutralized form. If the alkyl oxy aromatic sulfonate is in the overbased form, then the acid component is either in the acidic form or in the neutralized form.
