CAS No:7664-38-2
Molecular Formula: H3PO4
Molecular Weight: 97.99
Melting point: 21 ºC
Boiling point: 158 ºC
Solubility in water: MISCIBLE
Properties: It is in Colorless, transparent and syrupy liquid or rhombic crystalline; It is odorless and tastes very sour; its melting point is 42.35ºCºC and when heated to 300ºCºC it will become into meta phosphoric acid; its relative density is 1.834 g/cm3; it is easily soluble in water and resolves in ethanol; it may irritate human skin to cause phlogosis and destroy the issue of human body; it shows corrosiveness being heated in ceramic vessels; it has got hydroscopicity.
Uses: Technical grade phosphoric acid may be used to produce variety of phosphates, electrolyte treatment liquids or chemical treatment liquids, refractory mortar with phosphoric acid and inorganic coheretant. It is also used as a catalyst, drying agent and cleaner. In coating industry it is used as a rust-proof coating for metals; As a acidity regulator and nutrition age nt for yeast food grade phosphoric acid may be applied to flavors, canned food and light drinks as well as used in wine brewery as a nutrients source for yeast to prevent the reproduction of useless bacteria.
