Product Description

Phosphorous acid CAS 10294-56-1 13598-36-2 Water Purification Chemicals

 

Description:

 

Phosphorous acid is a kind of inorganic compounds, its chemical formula is H3PO3, molecular weight of 82.00.Soluble in water and alcohol.Slow oxidation into phosphoric acid in the air, heated to 180 ℃ when broken down into phosphoric acid and phosphine (highly toxic, explosive).Phosphorous acid is dibasic acid, which is slightly more acidic than phosphoric acid. It has strong reducibility and is easy to reduce silver ion (Ag+) to silver metal (Ag). It can reduce sulfuric acid to sulfur dioxide.Have strong hygroscopicity and deliquescence, corrosive.

Application:

 

The most important use of phosphorous acid is the production of phosphonates which are used in water treatment. Phosphorous acid is also used for preparing phosphite salts, such as potassium phosphite. These salts, as well as aqueous solutions of pure phosphorous acid, have shown effectiveness in controlling a variety of microbial plant diseases, in particular, treatment using either trunk injection or foliar containing phosphorous acid salts is indicated in response to infections by phytophthora and pythium-type plant pathogens (both within class oomycetes, known as water molds), such as dieback/root rot and downy mildew. Anti-microbial products containing salts of phosphorous acid are marketed in Australia as 'Yates Anti-Rot'; and in the United States of America, for example, aluminum salts of the monoethyl ester of phosphorous acid (known generically as 'Fosetyl-Al') are sold under the trade name 'Aliette'. Phosphorous acid and its salts, unlike phosphoric acid, are somewhat toxic and should be handled carefully.
