Phosphorous acid is a white colorless crystal. It is an intermediate in the preparation of other phosphorus compounds. The most important use of phosphorous acid (phosphonic acid) is the production of phosphites (phosphonates) which are used in water treatment. Phosphorous acid is also used for preparing phosphite salts, such as potassium phosphite. These salts, as well as aqueous solutions of pure phosphorous acid, are fungicides.
Phosphorous acid is mainly used in the plastics industry as reducing agent, nylon whitening agent, plasticizers for plastics, synthetic fibers, and so on. It also used as raw materials of herbicides, fungicides and water stabilizer.
