Abstract: METHOD OF PREPARING A LUBRICATING OIL COMPOSITION CONTAINING A PARTIALLY HYDROLYZED OVERBASED SULFURIZED CALCIUM ALKYLPHENOLATE DETERGENT OF ANTIOXIDANT AND SKIN FORMING RESISTANT PROPERTIES AND OF REDUCED VISCOSITY AND IMPROVED FLTERABILITY COMPROSING FIRST CONTACTING A SULFURIZED NORMAL CALCIUM ALKYLPHENOLATE WITH A CALCIUM ALKOXYALKOXIDE WHILE SIMULTANEOUSLY BLOWING THE REACTION MIXTURE WITH NITROGEN GAS AT A RATE OF BETWEEN ABOUT 0.25 AND 0.6 S.C.F.H/GALLON OF REACTION MIXTURE, SUBSEQUENTLY STRIPPING THE REACTION MIXTURE WITH SAID GAS AT A RATE OF BETWEEN ABOUT 0.25 AND 0.6 S.C.F.H./GALLON OF RESULTANT MIXTURE AND THEN SECOND CONTACTING THE STRIPPED MIXTURE WITH WATER WHILE SIMULTANEOUSLY BLOWING DURING SAID SECOND CONTACTING THE STRIPPED MIXTURE WITH SAID GAS AT A RATE OF BETWEEN ABOUT 0.1 AND 0.2 S.C.F.H./GALLON OF STRIPPED MIXTURE.
