Abstract

A new method for the prepn. of n-phosphonomethyl glycine by the phosphonomethylation of glycine in an aq.-alcoholic soln., characterised in that it comprises: i) reacting glycine with an aq.-alcoholic soln. of HCHO in the presence of a base selected from the gp. consisting of alkali and alkaline earth hydroxides; ii) reacting the soln. thus obtd. with trialkylphosphite and; iii) effecting hydrolysis in an aq. medium and recovering the N-phosphonomethyl glycine by crystallisation.
