Abstract: Imidazolidione-N-ethylphosphonic acid was synthesized with carbamide and ethylenediaminoethylphosphonic acid which was prepared with ethylenediamine and chloroethylphosphonic acid .The title product was character ized by elementary analysis,IR, 1HNMR and potentiometric titration. The pH v alue of the reaction mixture has great influence on the yield of the product.
