(FR) PURIFICATION DE N-(PHOSPHONOMÉTHYL)GLYCINE
Abstract: front page image
(EN)The present invention is a process for the purification of glyphosate (PMG) comprising: 1) dissolving or suspending a material comprising PMG in water, in the presence of a base, to produce a composition comprising a PMG salt in an aqueous base, contacting the composition with an acid, such that the PMG salt is neutralized, forming a precipitate of PMG, and 3) isolating the precipitate of PMG. with the proviso that the composition of step 1) is not concentrated or filtered using a nanofiltration membrane.
(FR)La présente invention est un procédé pour la purification de glyphosate (PMG) comprenant : 1) de dissoudre ou mettre en suspension une matière comprenant du PMG dans de l'eau, en présence d'une base, pour produire une composition comprenant un sel de PMG dans une base aqueuse, 2) de mettre en contact la composition avec un acide, d'une façon telle que le sel de PMG soit neutralisé, formant un précipité de PMG et 3) de séparer le précipité de PMG, à condition que la composition de l'étape 1) ne soit pas concentrée ou filtrée en utilisant une membrane de nanofiltration.
