Cas number 7681-53-0
Molecular formula NaH2PO2
Molecular weight 87.98
Sodium hypophosphite
White powder or colorless crystal, deliquescent and odorless. Salty. Weathered in dry air, slightly hygroscopic in humid air. Phosphine precipitates and ignites spontaneously under strong heat. Soluble in 1 part cold water, 0.15 part boiling water, soluble in boiling ethanol and glycerin, soluble in cold ethanol, slightly soluble in absolute ethanol, insoluble in ether The aqueous solution was neutral. There is a strong reduction. Grinding with chlorate or oxidant can cause an explosion. Q / (HG) SJ 711-1996
