ABSTRACT:
This invention relates to novel organic phosphonate compounds which can be used as water treatment agents. More specifically, this invention relates to 1,1 -diphosphonic acid N-oxides and water-soluble salts thereof for control of corrosion and scale in aqueous systems. Preferred N-oxides are morpholinomethane-1,1-diphosphonic acid N-oxide and N,N-dimethylaminomethane-1,1-diphosphonic acid N-oxide.
