Ammonium hypophosphite Chemical Properties,Uses,Production

Chemical Properties

white crystals


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].


Evolves flammable and toxic fumes on heating.

Health Hazard

Non-toxic or low toxicity unless heated to decomposition (240°C).

Purification Methods

Crystallise it from hot EtOH.
