Phosphorous Acid H3PO3 98.5% 99.0% Crystal Powder CAS 13598-36-2 

Product Description
 

English name:      Phosphorous acid    H3PO3   

BRAND:                 KAGRO    

CAS No.:               13598-36-2

Molecular weight: 81.99

Appearance:         White crystal

Certificate :           COA        

Character:             Achromatic crystal,density1.65g/m3,better hygroscopi-city,dissolved easily in the water,has corrosive characteristics

Usage:                   Widely used as the raw materials to make phosphorous acid salt,used as the raw materials for making of plasticstabilizator in the plastic industry,used as reducer in chemical reaction,also used in the olefin industry, 
agricultural chemical industry and so on.

Agrochemical :Phosphorous acid is used to prepare phosphite salts, such as potassium phosphite, which serve as excellent agricultural fungicides. These salts, in addition to aqueous solutions of pure phosphorous acid, are very effective in controlling a variety of microbial plant diseases. An important and nutritious element in all living species, phosphorous compounds are also applied extensively as fertilizer e.g. phosphites, phosphonates or phosphates.

Life Science : Used in chemical reactions as a reducing agent that is somewhat less vigorous than the related Hypophosphorous Acid

Oil & Gas : Phosphorus based compounds are used extensively in the oil industry as additives. These chemicals have properties which aid lubrication, oxidation and inflammability. They also have good thermal and cold resistance attributes. e.g. tributyl phosphate, tris(2-ethylhexyl) phosphate

Plastics & Polymers : Phosphorus compounds are used as PVC stabilsers to prevent decomposition and impart enhanced resistance to daylight, weathering and heat ageing. As lead based stablisers are being phased out within Europe, materials such as calcium phosphite are now widely used.

Water Treatment : One of the most important use of phosphorous acid is the production of phosphonates for industrial water treatment. Phosphonates are employed as chemical additives to function in a wide range of antiscalants and corrosion inhibitors, because they have high stability in the presence of oxidizing agents e.g. 2-phosphonobutane-1,2,4-tricarboxylic acid.
