| Hazard Information | Back Directory | [Chemical Properties]
white crystals | [Uses]
As catalyst in polyamide manufacture. | [General Description]
White crystalline solid. Sinks and mixes with water. | [Hazard]
Evolves flammable and toxic fumes on heating. | [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]. | [Air & Water Reactions]
Water soluble. AMMONIUM HYPOPHOSPHITE(7803-65-8) liberates spontaneously flammable phosphine at about 240°C [Mellor 8:880 1946-47]. | [Health Hazard]
Non-toxic or low toxicity unless heated to decomposition (240°C). | [Purification Methods]
Crystallise it from hot EtOH. | [Flammability and Explosibility]
