Stabilized substituted aminomethane-1, 1-diphosphonic acid n-oxides and use thereof in preventing scale and corrosion

摘要

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.
