    Abstract: The present invention relates to a process for the preparation of phosphonomethylglycine in which N-phosphonomethyliminodiacetic acid N-oxide is brought into contact with a catalytically active quantity of at least one catalyst, selected from amongst a thionyl halide, ammonium dithionite or an alkali metal dithionite, a dialkyl sulfite, sulfur dichloride, sulfur dioxide and sulfurous acid, in a reaction chamber by metering the N-phosphonomethyliminodiacetic acid N-oxide into the reaction chamber in such a way that always at least 50% of the N-oxide metered into the reaction chamber are converted.
