Diamidodiphosphoric Acid, (NH2)2P2O3(OH)2, was prepared by the action of phosphoryl chloride at low temperatures on ammonia in the presence of some water, thus
2NH3 + 2POCl3 + 3H2O = 6HCl + (NH2)2P2O3(OH)2
It may also be obtained by several other reactions. The diammonium salt has been prepared in the crystalline state and various other salts as precipitates. |
