The invention relates to a method for producing N-phosphonomethylglycine by reacting a hexahydrotriazine compound with a triacyle phosphate in an organic solvent and the saponification of the phosphono compound which is obtained after previous extraction into an aqueous phase, and separation of the organic phase. According to the invention, said method prevents decomposition of the organic solvent during saponification.
