Method for preparation of N-phosphonomethylglycine |
| abstract |
A method for the preparation of N-phosphonomethylglycine is disclosed which comprises the steps of: n (1) reacting N-(diethylphoshonomethyl)iminobisethanol in an oxygen free atmosphere with an alkali metal hydroxide selected from the group consisting of sodium hydroxide and potassium hydroxide, in the presence of water as solvent and a catalyst selected from the group consisting of zinc oxide and cadmium oxide at a high temperature and pressure for a sufficient period of time to cause the reaction to go to completion, and n (2) acidifying the product formed. |
