Abstract (en)
[origin: EP0541333A1] The invention provides a process for the production of N-(phosphonomethyl)glycine, also known as glyphosate. The process comprises hydrogenating a mixture of glyoxylic acid and aminomethylphosphonic acid, the mixture having been enzymatically prepared in situ by the reaction of glycolic acid and oxygen in an aqueous solution containing aminomethylphosphonic acid and the enzymes glycolate oxidase and catalase.
Abstract (fr)
L'invention concerne un procédé de production de mélanges d'acide glyoxylique et d'acide aminométhyl phosphonique ainsi que la production ultérieure de N-(phosphonométhyl)glycine, également connu sous le nom de glyphosate. Le procédé comprend la préparation in situ d'un mélange d'acide glyoxylique et d'acide aminométhylphosphonique (AAMP) par réaction enzymatique d'acide glycolique et d'oxygène dans une solution aqueuse en présence d'acide aminométhylphosphonique et de catalyseurs consistant en une glycolate oxydase et une catalase. Le mélange obtenu est ensuite hydrogéné pour produire N-(phosphonométhyl)glycine, un agent phytotoxique et herbicide de post-émergence.
