Abstract
Magnesium bis(phosphorodiamidate) hexahydrate and calcium bis(phosphorodiamidate) dihydrate were made by adding an aqueous solution of magnesium chloride or calcium chloride to a sodium phosphorodiamidate solution. These phosphorodiamidates reacted with the water of crystallization and/or adsorbed water to produce phosphoramidate and orthophosphate. They also reacted with HCl gas, acetic acid, and oxalic acid to make polyphosphates and phosphates with amino and/or imino groups. Several typical reactions are as follows: (Remark: Graphics omitted.) where M and HA stand for alkaline earth metal and acid respectively.
