| Ammonium hypophosphite Usage And Synthesis |
| Chemical Properties | white crystals |
| Uses | As catalyst in polyamide manufacture. |
| General Description | White crystalline solid. Sinks and mixes with water. |
| Air & Water Reactions | Water soluble. Ammonium hypophosphite liberates spontaneously flammable phosphine at about 240°C [Mellor 8:880 1946-47]. |
| Reactivity Profile | Ammonium hypophosphite liberates spontaneously flammable phosphine at about 240°C [Mellor 8:880 1946-47]. Some inorganic materials, such as hypophosphites, tend to form explosive mixtures with perchloric acid when hot [Analyst 84:215 1959]. |
| Hazard | Evolves flammable and toxic fumes on heating. |
| Health Hazard | Non-toxic or low toxicity unless heated to decomposition (240°C). |
| Flammability and Explosibility | Notclassified |
| Purification Methods | Crystallise it from hot EtOH. |
