Chemical Properties
Hypophosphorous acid is a reducing agent. Strong monobasic acid. The aqueous solution is acidic and can be gradually oxidized in the air at room temperature. Contact with H porogen will cause burning. Combustible by violent reaction with oxidizing agents. Decompose highly toxic phosphine gas by high heat, even explode. Corrosive. Hypophosphorous acid is often added to cool drinks because it is not absorbed. So the risk is small, but particularly concentrated hypophosphorous acid can harm the gastrointestinal tract.
Main Introduce
Hypophosphorous acid, also known as "hypophosphorous acid", is a colorless oil or deliquescent crystal, and is an important product of fine chemical industry. The main purpose is to be used as a reducing agent for electroless plating, to prevent the discoloration of phosphoric acid resin, and it can also be used as a catalyst and refrigerant for esterification reaction, especially for the production of high-purity sodium hypophosphite. There are many preparation methods, among which the common preparation methods in industry include ion exchange resin method and electrodialysis method.
