Yield:-

Reaction Conditions:

with oxygen in water at 100;Flow reactor;Reagent/catalyst;

Steps:

10
A portion of the pyrolyzed Pt/Fe on modified carbon catalyst (1.38 g) and an aqueous solution (448 ml) containingN-(phosphonomethyl)iminodiacetic acid (PMIDA) (50 g; 10% by weight) was charged to a 1 liter reactor. The chargemixture was heated to 100°C under nitrogen, after which molecular oxygen gas was introduced into the mixture at a rateof 2.111 g moles/kg-hr. The reaction mass was sampled at 6 minutes, 10 minutes, 15 minutes, 19 minutes and 22minutes after the start of oxygen flow. Each of these samples was analyzed for N-(phosphonomethyl)glycine (glyphosate),N-(phosphonomethyl)iminodiacetic acid (PMIDA), formaldehyde (CH2O), formic acid (HCO2H), N-methyl-N-phosphonomethyl(glycine) (NMG), phosphate ion (PO4) and aminomethylphosphonic acid (AMPA) + N-methylaminomethylphosphonicacid (MAMPA).
