PROCESS FOR PREPARING GLYOXYLIC ACID/DIALKYL AMINOMETHYLPHOSPHONATE MIXTURES |
摘要 |
The invention provides a process for producing mixtures of glyoxylate and a dialkyl aminomethylphosphonate and the subsequent production of N-(phosphonomethyl)glycine, also known as glyphosate. The process comprises preparing in situ a mixture of glyoxylate and a dialkyl aminomethylphosphonate (DEAMPA) by enzymatically reacting glycolic acid (glycolate) and oxygen in an aqueous solution in the presence of a dialkyl aminomethylphosphonate and catalysts consisting of glycolate oxidase and catalase. The resulting mixture can be hydrogenated and then subjected to hydrolysis to produce N-(phosphonomethyl)glycine, a post-emergent phytotoxicant and herbicide.
