摘要：A method of preparing N-phosphonomethylglycine comprising (a) reacting a triazine with an acyl halide to form the N-cyanomethyl-N-halomethyl amide of the acyl halide; reacting the said amide with a phosphite to form a phosphonate compound; and hydrolyzing said phosphonate to yield N-phosphonomethylglycine.
