FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to a novel method for synthesis of N-phosphonomethylglycine. Method involves interaction of hexahydrotriazine compound with triacyl phosphite in organic solvent, saponification of formed phosphonic compound after preliminary extraction into aqueous phase, separation of organic phase and precipitation of N-phosphonomethylglycine by pH value control in the range from 0.5 to 2.0. Invention prevents decomposition of an organic solvent in saponification.
EFFECT: improved method of synthesis.
