Abstract: The invention relates to a process for preparing N-phosphono-methylglycine by reacting a hexahydrotriazine compound with a triacyl phosphite in an organic solvent, hydrolyzing the resulting phosphono compound after prior extraction into an aqueous phase and separation from the organic phase. The process avoids decomposition of the organic solvent during hydrolysis.

Abstract: The present invention relates to a process for the recovery of N-phosphonomethylglycine from an aqueous mixture which contains N-phosphonomethylglycine, ammonium halides, and alkali metal or alkaline earth metal halides and optionally organic impurities in dissolved form, where (a) the pH of the mixture is adjusted to a value in the range from 2 to 8, (b) a separation of the mixture on a selective nanofiltration membrane is performed, a retentate which is richer in N-phosphonomethylglycine and poorer in halides and a permeate which is richer in halides and poorer in N-phosphonomethylglycine being obtained, and (c) the N-phosphonomethylglycine is recovered from the retentate. The process according to the invention makes possible the recovery of the N-phosphonomethylglycine with simultaneous separation of the halide salts.
