Characteristic and superiority

Phosphorous acid, 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,As a raw material for the manufacture of plastic stabilizers, it is also used in the production of synthetic fibers and phosphites
