Reaction Steps
The disodium salt of [bis(2hydroxyethyl)amino]methylphosphonic acid monohydrate (10.0 g, 0.04 mol) was reacted in a 40% solution of sodium hydroxide (6.4 g, 0.16 mol) and water (10.0 g) at 270° C. for 130 minutes. The product mixture gave N-phosphonomethyliminodiacetic acid (2.76 g, 33.2%), N-phosphonomethylglycine (2.68 g, 51.2%) and aminomethylphosphonic acid (0.56 g, 10.2%).
