Abstract
A process for the preparation of N-phosphonomethylglycine is disclosed which comprises preparing an N-alkyl-N-phosphonomethylglycine or its ester represented by formula (I), wherein R is an alkyl group represented by formula (Ia) and R<1>, R<2> and R<3> are indenpendently selected from the group consisting of hydrogen and alkyl having one to about four carbon atoms, and R<4>, R<5> and R<6> are independently selected from substituted and unsubstituted alkyl groups having from one to about six carbon atoms wherein any substitution on the alkyl group has electron withdrawing properties, and hydrogen, provided that R<4>, R<5> and R<6> cannot all be hydrogen; and thereafter treating the N-alkyl-N-phosphonomethylglycine with an acid, other than a hydrohalic acid, having a pKa value below about +3 in the presence of an organic acid to provide N-phosphonomethylglycine.
