Abstract

1428499 Preparing N-phosphonomethyl glycine and derivatives thereof MONSANTO CO 20 Dec 1973 [21 Dec 1972 6 Aug 1973] 59083/73 Heading C2P N-Phosphonomethyl glycine and its derivatives of the formula wherein M, M 1 and M 2 are each individually hydrogen, alkoxyalkyl groups, alkoxyalkoxyalkyl groups, alkyl groups of from 1 to 18 carbon atoms, alkali metal, alkaline earth metal, ammonium or organic ammonium provided that at least one of M, M 1 and M 2 is hydrogen, alkali metal or alkaline earth metal, are obtained by subjecting an aqueous electrolytic medium containing an N-organo-N-phosphonomethylamino acetic acid compound of the formula wherein R is selected from allyl, halogen-substituted allyl, benzyl, halosubstituted benzyl, 2,2,2-triphenylethyl, diphenylmethyl, 1,2- or 2,2-diphenylethyl, -CH 2 CH 2 OH, -CH 2 NO 2 , -CH 2 CN, -CH 2 C(O)C n H 2n+1 , -CH 2 -CH 2 OR<SP>1</SP>, -CH 2 Cl, -CH 2 CHO, -CH 2 CH 2 NR<SP>1</SP>R<SP>11</SP>, -CH 2 OR<SP>1</SP>, -CH 2 CCl 3 , CH 2 C(O)NR<SP>1</SP>R<SP>11</SP>, M 3 OOCCH 2 or (M 3 O)(M 4 O)P(O)CH 2 - wherein R<SP>1</SP> is C 1 -C 6 alkyl, R<SP>11</SP> is H or is as defined for R<SP>1</SP>, M 3 and M 4 are as defined for M, M 1 and M 2 , and n is 1 to 6 to an electromotive force to convert the amino acetic acid compound to N-phosphonomethyl glycine or derivative thereof. Preferably a 2% to 30% by weight solution of the compound II dissolved in 1À0 to 37% by weight aqueous HCl is charged into an electrolytic cell maintained at 25‹ to 110‹ C. and having noble metal, graphite or carbon electrodes and a current passed through at between 1 and 700 ma./cm.<SP>2</SP> for a time sufficient to effect the electrolytic conversion. The resultant solution may be vacuum evaporated to remove the aqueous HCl medium and volatile by-products and the residue dissolved in water and recovered by recrystallization on cooling the solution. Other acids, or bases or salts of such bases, may also be used to make the electrolytic solution conductive and a formaldehyde-scavenging agent, e.g. urea may be included in the medium. [GB1428499A]
