Abstract: A Cheap and fast synthetic method for tetraethy methy enediphosphonate hasbeen proposed.In nonpolar solvent, soft needle-like crystals of sodium diethylphosphonateis prepared.By adding dichloromethane to the salt,methylenediphosphonate is produced af-ter stirring for two days at room temperature.

Key words: tetraethy methy enediphosphonate, diethyl phosphonate, synthesis
