Physical and Chemical Properties


Phosphoric acid or orthophosphoric acid, chemical formula H3PO4, molecular weight 97.9724, is a common inorganic acid, is a medium strong acid. It is obtained by dissolving phosphorus tetroxide in hot water. Orthophosphoric acid is obtained commercially by treating apatite with sulfuric acid. Phosphoric acid dehydrates easily in air. Heat loses water to pyrophosphoric acid, and further loses water to metaphosphate. Phosphoric acid is mainly used in pharmaceutical, food, fertilizer and other industries, and can also be used as a chemical reagent.

Application


a.The most important use of phosphorous acid (phosphonic acid) is the production of basic lead phosphite, which is a stabilizer in PVC and related chlorinated polymers.

b.It is used in the production of basic lead phosphonate PVC stabilizer, aminomethylene phosphonic acid and hydroxyethane diphosphonic acid.

c.It is also used as a strong reducing agent and in the production of phosphorous acid, synthetic fibres, organophosphorus pesticides, and the highly efficient water treatment agent ATMP.

d.Ferrous materials, including steel, may be somewhat protected by promoting oxidation ("rust") and then converting the oxidation to a metalophosphate by using phosphoric acid and further protected by surface coating.
