Abstract
Abstract Process for preparing highly basic alkaline earth metal alkylphenates or sulfurized alkylphenates wherein the process comprises: A. FORMING AN ADMIXTURE OF ALKYLPHENOL OR SULFURIZED ALKYLPHENOL, NONVOLATILE DILUENT OIL, VOLATILE PROCESS SOLVENT AND WATER, B. ADDING AN OVERBASING AMOUNT OF ALKALINE EARTH METAL IN A GLYCOL ETHER AT A TEMPERATURE FROM ABOUT 20* TO ABOUT 55* C., c. adding a neutralizing amount of alkaline earth metal in a glycol ether at a temperature of about 55* to about 100* C., and D. REMOVING THE VOLATILE MATERIALS BY HEATING. The products are useful as additive agents for lubricating oils.
