Reaction Conditions

Reaction Steps

To 100 mL of water, 5 g of an activated carbon shown in Table 1 and 20.0 g of N-(phosphonomethyl)iminodiacetic acid were added. Into the mixture, 20.0 g of a hydrogen peroxide aqueous solution having a concentration of 30% by mass was added dropwise over 3 hours at 65° C. under stirring while maintaining the temperature of 65° C. After the completion of the dropping, the resulting mixture was maintained for 1 hour, and N-(phosphonomethyl)glycine was then isolated as a crystal. The isolated crystal was quantitatively determined by a high-speed liquid chromatography, and the weight yield and purity were measured.
