Abstract

1494197 Electrolytic preparation of N- methylphosphonoglycine IMPERIAL CHEMICAL INDUSTRIES Ltd 6 Nov 1974 [30 Nov 1973] 55663/73 Heading C2P [Also in Division C7] N-phosphonomethylglycine or a salt thereof is prepared by subjecting an aqueous solution of N-phosphonnmethyliminodiacetic acid or a salt thereof to electrolysis. Preferably the anode is maintained at a potential of 0À8 to 1À2 volts with reference to a standard calomel electrode and the electrodes are made of carbon, a noble metal or a metal oxide. Preferably the pH of the aqueous solution is greater than 7 and the solution is stirred or otherwise agitated to bring about movement of the aqueous solution relative to the anode. The electrolysed solutions may be formulated for use as herbicides. Reference has been directed by the Comptroller to Specification 1,428,499.
