nature
Colorless crystal. The relative density is 1.651(21.2ºC). Melting point 73,6ºC. Boiling point 200ºC (decomposition). Soluble in water and alcohol. It is slowly oxidized into orthophosphate in the air and decomposes into orthophosphate and phosphine (highly toxic) when heated to 180 ° C. Phosphorous acid is a dibasic acid, its acidity is slightly stronger than phosphoric acid, it has strong reducibility, easy to reduce Ag ions to silver metal, can reduce sulfuric acid to sulfur dioxide. Strong hygroscopicity and deliquability, corrosive.
preparation
The industrial production methods are phosphorus trichloride hydrolysis and phosphite process.
Hydrolysis method: Phosphorus trichloride is slowly hydrolyzed with water under stirring to generate phosphorous acid, which is refined, cooled, crystallized and decolorized to obtain the finished product of phosphorous acid. Hydrogen chloride produced in the production process can be recycled into hydrochloric acid.
use
It is a raw material for the manufacture of phosphite, and it is also a raw material for the manufacture of plastic stabilizers (such as: lead disalt phosphate) and organophosphorus pesticides. Used as a stabilizer for polycarbonate. Also used as an antioxidant for nylon 1010.
