SpecificationsUsed as the raw materials to make phosphorous 
acid salt,plastic stabilizator industry,used as reducer in 
chemical reaction.. 

Purity:

>/=99%

Properties:
Phosphorous acid is a colorless crystal. It can be slowly oxidized to phosphoric acid in the air. When heated to 180 °C, it can be decomposed into phosphoric acid and phosphine (highly toxic). As a dibasic acid, it has slightly ber acidity than phosphoric acid. Phosphorous acid has b reducibility and can easily reduce Ag+ to metal silver. It can also reduce sulfuric acid to sulfur dioxide. It is corrosive and has b hygroscopicity. 
Relative Density: 1.651 (21.1 °C)
Melting Point: 73.6 °C
Boiling Point: 200 °C (Decomposes)
Solubility: Easily soluble in water and alcohol.

 

Applications:
Phosphorous acid is mainly used in the production of phosphates, synthetic fibers and organophosphorus pesticides, etc.. It is also used in producing high performance water treating agent ATMP.
