摘要： This invention relates to the preparation of N-(phosphonomethyl)glycine ('glyphosate') from N-(phosphonomethyl)iminodiacetic acid ('PMIDA'), and more particularly to a method 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 whereby the generation of carbon dioxide in the reaction zone is monitored.

摘要： A process is provided for destroying formic acid and/or formaldehyde in an aqueous, organic acid waste stream by contacting the stream with a supported precious metal catalyst and passing air or molecular oxygen gas through the solution to promote chemical oxidation. The invention is a safe, practical and cost effective alternative to bio-system treatment of these compounds using microorganisms. The process of the invention may be practiced in either a batch or continuous mode and, in accordance with the invention, formic acid present in a stream at a level of 3800 ppm and formaldehyde present in an amount of 5800 ppm can be reduced respectively to levels of 200 ppm or less.
