ABSTRACT:
Aminoalkylenephosphonic acids and their alkali metal salts prepared by a reaction utilizing a primary or secondary tetrahydrothiophenamine 1,1-dioxide or the hydrochloride thereof, an aldehyde or a ketone, and orthophosphorous acid are useful in the control of scale and sludge deposition in aqueous systems. When used in combination with known corrosion inhibitors they show synergistic results in inhibiting corrosion of metal surfaces in contact with an aqueous system that is normally corrosive to such metals.
