Abstract: AN ALKALI METAL SALT AND PARTICULARLY A LITHIUM SALT OF SALICYLIC ACID OR RELATED HYDROXY BENZOIC ACID IS INCORPORATED INTO A LUBRICATING OIL OR GREASE AS AN ANTIOXIDANT BY SPONIFYING AN ALIPHATIC ALCOHOL ESTER OF THE HYDROXY BENZOIC ACID AND THEN REMOVING THE WATER AND ALCOHOL FORMED IN THE REACTION. IMPROVEMENTS OVER PRIOR ART METHODS INCLUDE BETTER PARTICLE SIZE DISTRIBUTION AND LOWER COST.
