Phosphorous Acid

Phosphoric Acid

Phosphorous Acid is primarily used as a chemical intermediate in the production of various phosphorus compounds, particularly as a key component in the manufacturing of PVC stabilizers like basic lead phosphite, and also serves as a strong reducing agent in organic synthesis; its applications include the production of synthetic fibers, organophosphorus pesticides, and highly efficient water treatment agents like ATMP (aminotrimethylene phosphonic acid).

Phosphoric Acid Food Grade is used as an ingredient in foods and beverages. Phosphoric Acid is typically used for pH control in the food industry, for example in the manufacture of cheese products, fats, and shortenings. It is also used in the beverage industry in soft drinks, particularly cola. Itâ??s used for ph control in manufacture of imitation jellies, as a nutrient in production of yeast, to control bacteria growth in selected processed food, as a flocculating agent for clarification of sugar juices after liming process and in the Manufacture of phosphate salts.

Product Name: Phosphorous acid Other Names: Phosphonic acid; hydrogen phosphonate; phosphorus(+3) trihydride cation trihydroxide; Orthophosphorus; Orthophosphorous acid; Ortho-Phosphorous acid Molecular Formula: H3PO3 UN No.:2834 HS No.: 2811199090 CAS No.: 13598-36-2 EINECS No.:237-066-7 Hazard Class: 8 Purity:98% 99% Appearance: white crystal Physical and Chemical Properties Phosphorous acid (or phosphonic acid (singular)) is the compound described by the formula H3PO3. This acid is diprotic (readily ionizes two protons), not triprotic as might be suggested by this formula. Phosphorous acid is an intermediate in the preparation of other phosphorus compounds. Organic derivatives of phosphorous acid, compounds with the formula RPO3H2, are called phosphonic acids.
