摘要:
An improved process is provided for the manufacture of N-phosphonomethylglycine from N-phophonomethyliminodiacetic acid in the presence of a molecular-oxygen containing gas utilizing a catalytically active carbonaceous char. The improvement is provided by the use of a carbonaceous char capable of rapidly decomposing hydrogen peroxide in an aqueous solution.
