Abstract: AMINOALYLENE PHOSPHONATES CONTAINING SULFUR, OXYGEN, SULFOXIDE OR SULFONE GROUPS AND THEIR USE AS CORROSION INHIBITORS IN AQUEOUS SYSTEMS. IT HAS BEEN DISCOVERED THAT COMPOUNDS OF THIS NATURE NOT ONLY YIELD SATISFACTORY ANODIC INHIBITION, BUT ALSO VERY DESIRABLE CATHODIC CORROSION INHIBITION WHEN ADDED TO AQUEOUS SYSTEMS IN AN EFFECTIVE AMOUNT, E.G. RANGING FROM 1 TO 1000 PARTS PER MILLION PARTS BY WEIGHT OF THE AQUEOUS SYSTEM.
