ABSTRACT:
A method is disclosed for preparing overbased petroleum oxidates which comprises carbonating a petroleum oxidate in the presence of a base selected from the group consisting of alkali metal compounds and alkaline earth metal components. The petroleum oxidate is made by oxidizing petroleum oil in the presence of a base. The overbased petroleum oxidates are useful as rust inhibitors, dispersants, detergents, friction modifiers and as a substrate for overbased sulfonates, phenates, and salicylates. The overbased sulfonates, phenates and salicylates are easily overbased and have improved storage stability and improved rust inhibition.
