Abstract
Procedeul de preparare a triesterului N-fosfonometilglicinei, caracterizat prin aceea ca tetraetilesterul de acid N-fosfono-metiliminodiacetic este supus electrolizei la un voltaj de circa +1,6 V fata de electrodul de calomel saturat si amperaj cuprins între 3 si 30 mA timp de 5 h în prezenta de hexafluorofosfat de amoniu, în mediu de acetonitril, la temperatura camerei si presiune normala, apoi amestecul de reactie este supus concentrarii, iar rezidul este prelucrat în vederea separarii produsului de reactie în mod cunoscut.
