Phosphorous Acid Suppliers, Phosphorous Acid Manufacturers.
Molecular Formula: H3PO3
UN No.: 2834
Molecular Weight: 82.00
CAS No.:13598-36-1 or 10294-56-1
Properties:
Pure product is white crystals, specific gravity 1.651(21.2°C). M.P. 73.6°C, B.P. 200°C. Soluble in water and ethanol easily, and it will be oxidized into H3PO4 in the air slowly. Be decomposed into H3PO4 and phosphine when be heated to the temperature 180°C.H3PO3 is a kind of diacid, its acid-stage is higher than H3PO4. Be oxidized easily and has strong hygroscope and corrosively.
Usage:
Phosphorous acid is mainly used in the production of phosphates, synthetic fibers and organ phosphorus pesticides, etc. It is also used in producing high performance water treating agent ATMP.
