Control of n-(phosphonomethyl)iminodiacetic acid conversion in manufacture of glyphosate |
| abstract |
This invention relates to the preparation of N-(phosphonomethyl)glycine (“glyphosate”) from N-(phosphonomethyl)iminodiacetic acid (“PMIDA”), and more particularly to methods for control of the conversion of PMIDA, for the identification of reaction end points relating to PMIDA conversion and the preparation of glyphosate products having controlled PMIDA content. One such method involves obtaining a series of Fourier transform infrared (“FTIR”) analyses of the PMIDA content of the aqueous reaction medium or a sample thereof during the course of the reaction. From a plurality of FTIR analyses, a projection is made of the batch reaction time or continuous oxidation residence time within the oxidation reaction zone at which a target conversion or end point may be anticipated to be attained or is attained. |
