Zusammenfassung:FIELD: organic chemistry, chemical technology. ^ SUBSTANCE: invention relates to the improved method for preparing N-phosphonomethylglycine. Method involves interaction of derivative of hexahydrotriazine of the formula (II): ^ wherein X represents CN, COOZ, CH2OY and others; Z and Y represent hydrogen atom and others with triacylphosphite of the formula: P(OCOR3)3 (III) wherein R3 means (C1-C18)-alkyl or aryl that can be substituted. The prepared product is hydrolyzed and (if X represents CH2OY) oxidized. The proposed method is a simple in realization, economy and provides high degree of the end product purity. ^ EFFECT: improved preparing method. ^ 19 cl, 11 ex
