Reaction Steps
The procedure of Example 5 was followed in heating the disodium salt of [bis(2hydroxyethyl)amino]methylphosphonic acid trihydrate (2.0 g, 0.007 mol) in a 20% solution of potassium hydroxide (1.5 g, 0.02 mol) and sodium hydroxide (1.1 g, 0.03 mol) in water (10.0 g) at 250° C. for 60 minutes. Product isolation gave N-phosphonomethylglycine (0.57 g, 50.4%) and aminomethylphosphonic acid (0.14 g, 18.7%).
