Beschreibung
Zusammenfassung:The invention provides a process and the product of process for the preparation of N-phosphonomethyl-glycine comprising the oxidation of an aqueous suspension of N-phosphonomethyl-imino diacetic acid in the presence of a catalyst with oxygen or an oxygen-containing gas. Comparing the process of the invention with the known processes, specific conversion is considerably increased and significant amounts of energy can be saved.
