Phosphoric acid (orthophosphoric acid, monophosphoric acid or phosphoric(V) acid) is a colorless, odorless phosphorus-containing solid, and inorganic compound with the chemical formula H3PO4. It is commonly encountered as an 85% aqueous solution, which is a colourless, odourless, and non-volatile syrupy liquid. It is a major industrial chemical, being a component of many fertilizers.
Transparent colorless viscous solution, odorless. General content of 75% ~ 85%. Continue to concentrate to obtain colorless columnar crystals, density (18 deg C) 1.834g/cm3, melting point 42.3 deg C, boiling point 158 deg C, freezing point 21.1 deg C. It was heated to 150 ° C. And changed to pyrophosphoric acid and to metaphosphoric acid at about 215 ° C., with a vapor pressure of 300. Strong deliquescence. Miscible with water and ethanol.
In the manufacture of superphosphates for fertilizers, other phosphate salts, polyphosphates, detergents. Acid catalyst in making ethylene, purifying hydrogen peroxide. As acidulant and flavor, synergistic antioxidant and sequestrant in food. Pharmaceutic aid (solvent).
