Characteristic and superiority
Phosphorous acid, inorganic compounds, soluble in water and alcohol. In the air slowly oxidized to orthophosphoric acid, heated to 180 ° C when the decomposition of orthophosphoric acid and phosphine (highly toxic, explosive). Phosphoric acid is a dibasic acid, its acidity is slightly stronger than phosphoric acid, it has a strong reduction, easy to silver ions (Ag +) reduced to metallic silver (Ag), sulfuric acid can be reduced to sulfur dioxide. Strong hygroscopicity and deliquescence, corrosive. Phosphoric acid is mainly used as a reducing agent, nylon whitening agent, also used as phosphite raw materials, pesticide intermediates and organic phosphorus water treatment agent raw materials.
Application
1, used as a reducing agent, nylon whitening agent, also used as phosphite raw materials, pesticide intermediates,
2, is the manufacture of phosphite raw materials, but also the manufacture of plastic stabilizers (such as: salt) and organophosphorus pesticide raw materials. Used as a stabilizer for polycarbonate. Also used as antioxidant for nylon 1010.
3, used as chemical reagents,
4, water treatment
5, determination of mercury, gold, silver and lead, reducing agent, test iodic acid, copper and cadmium. Industrial phosphorous acid is the raw material for making plastic stabilizers. Also used in synthetic fibers and phosphites.
