Potassium hypophosphite Usage And Synthesis

Chemical Properties

White, opaque crystals or powder; pun- gent saline taste; very deliquescent. Soluble in water and alcohol; decomposed by heat.

Production Methods

Potassium hypophosphite, KH2PO2, white solid, soluble, formed (1) by reaction of hypophosphorous acid and potassium carbonate solution, and then evaporating, (2) by reaction of potassium hydroxide solution and phosphorus on heating (poisonous phosphine gas evolved).

Hazard

Moderate fire risk, may explode if ground with chlorates, nitrates, or other strong oxidizing agents.

Flammability and Explosibility
