ABSTRACT:
A process for preparing highly basic magnesium sulfonates useful as lubricants including (a) forming an admixture of an oil-soluble sulfonic acid, a previously overbased magnesium sulfonate having a TBN in excess of about 200, a lower alkanol, and a volatile solvent, (b) heating the admixture to neutralize the acid, (c) cooling the first admixture and then forming a second admixture by adding magnesium oxide, naphthenic acid, a lower alkanol and a diluent oil, (d) carbonating the second admixture with carbon dioxide, while simultaneously adding water and ammonia or an ammonium compound as promoters, during the addition of about the first 25% of the carbon dioxide, (e) heating the carbonated solution to remove water and the lower alkanol, (f) further carbonating the solution for a short time between 180.degree. F. and 220.degree. F., (g) heating the solution to remove water, (h) diluting the solution with volatile solvent, (i) clarifing the solution, and (j) removing the volatile solvent, preferably by heating under vacuum.
