    摘要: 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.
