Hypophosphoric Acid, H3PO3, together with phosphorous and phosphoric acids, was first produced by the slow oxidation of phosphorus in the air and in the presence of water at a moderately low temperature (5 to 10 C.); it was isolated through the formation of a sparingly soluble sodium salt.

It was also produced by the slow oxidation of phosphorus with silver nitrate in neutral or ammoniacal solution.

Oxidation of yellow phosphorus by copper nitrate in the presence of nitric acid at about 60 C. also yielded hypophosphoric acid along with phosphoric acid and copper phosphide. These reactions have been expressed by the equations

4P + 5Cu(NO3)2 + 8H2O = Cu3P2 + 2Cu + 10HNO3 + 2H3PO4
4P + 4Cu(NO3)2 + 6H2O = Cu3P2 + Cu + 8HNO3 + H4P2O6

Better yields were obtained by the electrolysis of 1 to 2 per cent, sulphuric acid using anodes of copper or nickel phosphide.
Hypophosphorous Acid Uses
Bleaching Agent

Hypophosphorous Acid is used as a bleaching or decolorizing agent for plastics, synthetic fibers, and chemicals

Color Stabilizer

HPA is used as a decolorizing agent and for color stabilization during the manufacture of chemicals and several plastics including: nylon fibers, polyamides, polyester fiber, polyacrilonitrile, alkyd rsins, epoxies, fatty acid esters, and glycerols.

Hypophosphite Salts

Hypophosphorous Acid is used in the production of Hypophosphite Salts (i.e., Calcium, Magnesium, Manganese, Potassium, Iron, and Ammonium) which are in turn used in synthetic fibers as wetting dispersing, emulsifying, and anti-static agents

Chemical Intermediate

Used in organic synthesis and organo phosphinic acid production

Neturalizing Agent

Used as a moderately strong monobasic acid

Catalyst

Used as a polymerization and polycondensation catalyst

Wetting Agent

Used as a wetting, dispersing, or emulsifying agent in electroplating

Reducing Agent

May be used for its strong but slow reducing action

Antioxidant

Hypophosphorous Acid may be used as an antioxidant

Pharmaceutical

HPA may be used as a stimulant in pharmaceuticals.

Hipofosforik Asit, H3PO3, fosfor ve fosforik asitlerle birlikte, fosforun havadaki yava oksidasyonu ve orta derecede dk bir scaklkta (5 ila 10 C) su varlnda retildi; Az znen bir sodyum tuzunun olumasyla izole edildi.

Ntr veya amonyakl zeltideki gm nitratla fosforun yava oksidasyonu ile de retildi.

Yaklak 60 C`de nitrik asit varlnda bakr nitrat ile sar fosforun oksidasyonu ayrca fosforik asit ve bakr fosfitle birlikte hipofosforik asit vermitir. Bu reaksiyonlar denklemlerle ifade edilmitir

4P + 5Cu (NO3) 2 + 8H2O = Cu3P2 + 2Cu + 10HNO3 + 2H3PO4
4P + 4Cu (NO3) 2 + 6H2O = Cu3P2 + Cu + 8HNO3 + H4P206

Bakr ya da nikel fosfat anotlar kullanlarak slfrik asidin yzde 1 ila 2`sinin elektrolizi ile daha iyi verim elde edildi.
