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.

Abstract: Synthesis of olefin from synthesis gas in the presence of at least a Fischer-Tropsch catalyst in a reaction column comprises introducing the synthesis gas into the beneath of the zone (A) of the reaction column and removing the obtained olefin from the beneath of the inlet for the synthesis gas. An independent claim is included for a mixture of olefin obtained by the above process.

Abstract: Described is 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. The catalyst may be selected from a thionyl halide, ammonium dithionite or an alkali metal dithionite, a dialkyl sulfite, sulfur dichloride, sulfur dioxide and sulfurous acid. The reaction is carried out 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 is converted.
