A PROCESS FOR PRODUCING COMPLEX BASIC ALUMINUM SOAP GREASES, WHICH COMPRISES MIXING APPROXIMATELY 1.5 TO 2.5 MOLAR PARTS OF A MIXTURE OF HIGHER FATTY ACIDS AND AROMATIC CARBOXYLIC ACIDS IN WHICH THE MOL RATIO OF HIGHER FATTY ACID TO AROMATIC CARBOXYLIC ACID IS IN THE RANGE FROM ABOUT 0.25:1 TO 4:1, APPROXIMATELY 1 MOLAR PART OF A LOWER ALUMINUM ALCOHOLATE, FROM 0 TO 1. 5 MOLAR PARTS OF WATER AND A LARGE MOLAR EXCESS OF AN OIL OF LUBRICATING VISCOSITY, HEATING THE RESULTANT MIXTURE TO A TEMPERATURE IN THE RANGE ABOUT 150* TO 300*F. UNTIL REACTION OF THE ACIDS WITH THE ALCOHOLATE IS SUBSTANTIALLY COMPLETE, THEN ADDING A QUANTITY OF WATER IN THE RANGE 0.05 TO 10 MOLAR PARTS AND AT LEAST SUFFICIENT TO BRING THE TOTAL WATER INTRODUCED TO ABOUT 0.5 MOLAR PARTS AND VIGOROUSLY AGITATING THE RESULTANT MIXTURE AT A TEMPERATURE FROM ABOUT 200*F.
