Physical and Chemical Properties | Character white square double cone crystal. relative density 1.59g/cm3 solubility in water. Insoluble in ethanol, ether. |
Use | For pharmaceutical applications |
white crystals with fluorescence. Soluble in water, its aqueous solution is neutral or weakly acidic, insoluble in ethanol and ether. The relative density was 1. 59 (12.5/4 ℃). It is easy to be weathered in dry air, and 5 molecules of crystal water are lost at 100 °c. It becomes anhydrous at 180 ° C., and when heating is continued, it decomposes and releases a flammable and extremely toxic phosphine gas.
hypophosphorous acid is neutralized with magnesium oxide (or magnesium hydroxide), and the precipitate is separated and dried to obtain magnesium hydrogen phosphate.
It is used in medicine for the manufacture of a medicament for the treatment of rheumatoid arthritis. The plastics industry is used as a stabilizer for plastics. It is also used as a flame retardant material. It is used in agriculture as an additive for chemical fertilizers and as an amendment for alkaline soils.
lined with plastic bag, coat paper plastic composite bag packaging, each bag of 25kg net weight, this product should be stored in a dry ventilation warehouse, during transport to prevent humidity, loading and unloading should be light, prevent package breakage and store separately from toxic substances.
