85 Orthophosphoric Acid

Phosphoric acid

85 orthophosphoric acid Introduction:

Phosphoric acid was prepared first by Robert Boyle in 1694 by dissolving phosphorus pentoxide in water. Phosphoric acid is probably the most important compound of phosphorus. It is the second largest inorganic chemical by volume, after sulfuric acid, marketed in the United States.
The single most important application of Phosphoric acid is manufacturing phosphate salts for fertilizers. Such fertilizer phosphates include sodium, calcium, ammonium, and potassium phosphates. Other applications are in metal pickling and surface treatment for removal of metal oxides from metal surfaces; electropolishing of aluminum; as a bonding agent in various refractory products such as alumina and magnesia; as a catalyst in making nylon and gasoline; as a dehydrating agent; in fireproofing wood and fabrics; in lithographic engraving; in textile dyeing; in dental cement; in coagulating rubber latex; in purifying hydrogen peroxide; and as a laboratory reagent. Dilute solutions of phosphoric acid are used as additives to carbonated beverages for a pleasing sour taste. Also, dilute acid is used in refining sugar; as a nutrient; and as a buffering agent in preparing jam, jelly, and antibiotics. The commercial phosphoric acid is 85% (w/w) in strength.

85 orthophosphoric acid use:

Matches are used to impregnate matchstick stems, which can prevent burnt matchstick stems from turning into charcoal instead of ash, making them safer to use;

Metallurgy is used to produce refractory mud and improve the service life of steelmaking furnaces;

Rubber is used as a coagulant for slurries and as a raw material for producing inorganic binders; Coatings used for metal anti rust paint; The food industry uses it as an acidic seasoning agent.
