A process of preparing the herbicide N-phosphonomethylylycine by oxidizing N-phosphonomethyliminodiacetic acid was investigated. The content of N-phosphonomethylylycine was above 75.04 %. The solid yield was 73.34 % and the total yield was 87.63 % when the reaction was carried out with the mol ratio of the manganese salt catalyst and N-phosphonomethyliminodiacetic acid as 0.04:1 at 80 degrees C under 0.4 MPa for 90 min.
