Ammonium diphosphate

When heated, (NH4)4P207 slowly loses ammonia and becomes amorphous.3 The X-ray powder diffraction patterns,3,9,11,13 optical properties,11 13 and infrared absorption spectra13 for (NH4)4P207 and the other ammonium diphosphates have been published. The crystal structure of tetraammonium diphosphate has been described.14... [Pg.159]

Ammonium diphosphate cannot be made by thermal dehydration of ammonium phosphates because both water and ammonia are split off, and the resulting product is a mixture of short-chain ammonium polyphosphates and short-chain polyphosphoric acids. Ammonium diphosphate usually is prepared from pure diphosphoric acid. The diphosphoric acid is crystallized from a polyphosphoric acid mixture containing 80% PjOs or made by running a solution of sodium diphosphate through an ion exchange column. The resulting diphosphoric acid then is treated with ammonia. Ammonium diphosphate also has been made by heating a mixture of urea and phosphoric acid, but by-products such as cyanuric acid are tedious to remove. The present method is based on the reac-...
