Abstract:
COORDINATED METAL COMPLEXES USEFUL IN LUBRICATING OILS AND HYDROCARBON FUELS TO IMPART DETRGENCY AND NEUTRALIZING PROPERTIES THERETO ARE OBTAINED BY REACTING AN ALKYLENE POLYAMINE WITH A MONOCARBOXYLIC ACID OR ANHYDRIDE, FOLLOWERED BY REACTING THE PRODUCT THUS OBTAINED WITH ALKENYLSUCCINIC ACID OR ANHYDRIDE AND A METAL SALT.
Abstract:
Metal complexes useful as additives in industrial fluids to improve the detergency and neutralizing characteristics thereof are produced by reacting a metal salt of an acid with an organic nitrogen compound. The specific metal complexes of the invention are formed by reacting an alkylene polyamine with an aldehyde, followed by reacting this product with (1) the metal salt and (2) an alkenylsuccinic acid or aldehyde in the order 1, 2 or 2, 1.
