ABSTRACT:
This invention relates to novel organic phosphonate compounds, and more particularly to ethoxylated N,N-bis-phosphonomethyl 2-(hydroxy) ethylamine N-oxides and their water soluble salts. These novel organic phosphonates are useful as water treatment agents which can be employed for the control of scale and/or corrosion.
