Reaction Steps

The disodium salt of [bis(2hydroxyethyl)amino]methylphosphonic acid monohydrate (4.0 g, 0.016 mol) was heated with 85% potassium hydroxide (15.0 g, 0.23 mol) at 250° C. for 75 minutes. Product isolation gave N-phosphonomethylglycine (0.31 g, 12.6%) and aminomethylphosphonic acid (1.0 g, 60.0%).
