Revised Date: 26 June 1995

A Cheap and fast synthetic method for tetraethylmethylenediphosphonate has been proposed. In nonpolar solvent, soft needle-like crystals of sodium diethylphosphonate is prepared. By adding dichloromethane to the salt,methylenediphosphonate is produced af-ter stirring for two days at room temperature.
