Method of incorporating metal complexes in a base oil

Claim 1

A PROCESS FOR PREPARING A DETERGENT CONCENTRATE WHICH COMPRISES HEATING A SAPONIFIABLE CARBOXYLIC ACID MATERIAL SELECTED FROM THE GROUP CONSISTING OF ALIPHATIC, CYCLO-ALIPHATIC, AROMATIC, AND ALKYLATED AROMATIC CARBOXYLIC ACIDS AND THEIR ESTERS, AND OXYGEN-CONTAINING DERIVATIVES THEREOF, WITH AN EXCESS OF A BASIC REACTING METAL COMPOUND IN THE PRESENCE OF ABOUT 1-30 PERCENT OF WATER BASED ON THE REACTION MIXTURE AT A TEMPERATURE IN ABOUT THE RANGE 125-250* F, DEHYDRATING THE REACTION PRODUCT, AND THEREAFTER HEATING A MIXTURE OF THE RESULTING PRODUCT COMPRISING METAL CARBOXYLATE AND ANY UNREACTED BASIC REACTING METAL COMPOUND, WITH ABOUT 30-90 PERCENT BY WEIGHT BASED ON THE TOTAL WEIGHT OF THE MIXTURE OF A HYDROCARBON LUBRICATING OIL AND ABOUT 1-40 PERCENT BY WEIGHT BASED ON THE TOTAL WEIGHT OF THE MIXTURE OF A DISPERSANT, AT A TEMPERATURE IN THE RANGE 400-850* F, SUFFICIENT TO EFFECT CONVERSION OF THE SAID METAL CARBOXYLATE TO METAL CARBONATE, UNTIL SUBSTANTIAL CONVERSION OF THE SAID METAL CARBOXYLATE TO THE SAID METAL CARBONATE HAS OCCURED AND THE SAID MIXTURE CONTAINS 0.1-15 PERCENT BY WEIGHT OF METAL CARBONATE IN STABLY DISPERSED FORM AND 0.5-30 PERCENT BY WEIGHT OF THE SAID METAL CARBOXYLATE, AND THEREAFTER COOLING THE SAID MIXTURE, SAID BASIC REACTING METAL COMPOUND BEING SELECTED FROM THE GROUP CONSISTING OF OXIDES, HYDROXIDES AND CARBONATES OF ALKALI METALS, ALKALINE EARTH METALS, MAGNESIUM, ZINC, CADMIUM, TIN LEAD AND MANGANESE, AND SAID EXCESS THEREOF BEING SUFFICIENT TO GIVE AN EXCESS OF 20-400 PERCENT BY WEIGHT OF METAL IN THE SAID MIXTURE OVER THAT CONTAINED IN THE NEUTRALIZED CARBOXYLIC ACID MATERIAL AND THE SAID DISPERSANT SAID LUBRICATING OIL BEING SUBSTANTIALLY STABLE UNDER THE SAID HEATING CONDITIONS IN THE RANGE 400-850* F., AND SAID DISPERSANT BEING SELECTED FROM THE GROUP CONSISTING OF METAL SULFONATES, METAL SALTS OF OLEFIN-PHOSPHORUS SULFIDE REACTION PRODUCTS, AND METAL SALTS OF ALKYL PHENOLS AND SUBSTITUTED ALKYL PHENOLS.
