Quantity: 20Metric Tons Specs:98%99% Price:1100 USD Metric Tons Payment Method: T phosphorous acid is 98.5% 99% CAS NO 10294-56-1 25KG/BAG 500KG/BAG 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. Phosphorous acid is a colorless crystal, relative Density: 1.651 (21.1 °C); melting Point: 73.6 °C; moiling Point: 200 °C (Decomposes); easily soluble in water and alcohol. 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 stronger acidity than phosphoric acid. Phosphorous acid has strong reducibility and can easily reduce Ag+ to metal silver. It can also reduce sulfuric acid to sulfur dioxide. It is hygroscopic and has strong hygroscopy. |
