説明Calcium hypophosphite has the molecular formula of Ca(H2PO2)2 and the molecular weight of 170.0631 g/mol. This salt can be prepared by the aqueous reaction of the carbonate or oxide with H3PO2: CaO + 2H3PO2 Ca(H2PO2)2 The salt is soluble in water (20 g/100 ml at 20°C) so that the solution must be evaporated to obtain crystals. Ca(H2PO2)2 has the CAS number of 7789-79-9 and the density of 1.59 g/cm3. It is composed of white square monoclinic crystalswhich are water soluble. It is insoluble in alcohol or ether.When heated to about 305°C, it disproportionates, forming calcium phosphate and phosphine: Ca(H2PO2)2 + heat CaHPO3 + PH3
使用As corrosion inhibitor; in nickel plating. Pharmaceutic aid (retards oxidation of ferrous salts).
