A process for the manufacture of alkylamino alkylene phosphonic acids is disclosed. In detail, a specific phosphonate is reacted with an agent selected to yield an alkylamino moiety substituted by a radical selected from OH, OR', NH2, NHR', N(R')2, NH, N, S, S-S and SH in aqueous alkaline medium having a pH of 8 or higher at a temperature of 0°C or higher.
