GB 1026366 describes the preparation of the tetrasodium salt of dichloromethylenebisphosphonic acid by refluxing dichloromethylene bisphosphonate tetraisopropyl ester with concentrated hydrochloric acid. The acidic solution was concentrated and twice azeotroped with isopropanol. Neutralisation of the acid with sodium hydroxide yielded the tetrasodium salt.
