Production of N-phosphonomethylglycine, useful as herbicide, comprises electrochemical oxidation of phosphonomethyliminodiacetic acid using anodically-polarized layer formed by deposition

摘要

A process for the production of N-phosphonomethylglycine (PMG) or corresponding salt by electrochemical oxidation of phosphonomethyliminodiacetic acid or corresponding salt (PMIDA) using an anode comprising an electrically conductive support material and an electrically conductive anodically polarized layer formed by in situ deposition.
