Product Description Product DescriptionHIGH QUALITY PHOSPHOROUS ACID CAS NO 13598-36-2Quality passed SGS&BV inspectionPhosphorous acid is an intermediate in the preparation of other phosphorus compounds.Water dissolution test: clear and colorless.Physical and chemical properties: a strong hygroscopicity and deliquescence, soluble in water and alcohol. Air slowly oxidizedinto orthophosphoric acid. 180 oC decomposition of phosphine and orthophosphoric acid. Corrosive.Acute toxicity LD50: 1895mg / kg (rat oral); 1700mg / kg (mouse oral)Application of Phosphorous acid:The most important use of phosphorous acid (phosphonic acid) is the production of phosphites (phosphonates) which are used inwater treatment. Phosphorous acid is also used for preparing phosphite salts, such as potassium phosphite. These salts, as well asaqueous solutions of pure phosphorous acid, are fungicides. Phosphites have shown effectiveness in controlling a variety of plantdiseases, in particular, treatment using either trunk injection or foliar containing phosphorous acid salts is indicated inresponse to infections by phytophthora and pythium-type plant pathogens (both within class oomycetes, known as water molds), suchas 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 phosphoricacid, are somewhat toxic and should be handled carefullyUsage of Phosphorous acid:1, Phosphorous acid is used as a reducing agent, nylon brightener, can also be used as raw materials for phosphite, pesticideintermediates and organic phosphorus water treatment agent;2, Phosphorous acid is the manufacture of phosphite raw materials, but also the manufacture of plastic stabilizers and organicphosphorus pesticide raw materials;3, Phosphorous acid can be used as a polycarbonate stabilizer;4, Phosphorous acid can be used as chemical reagents.Storage of Phosphorous acid:Stored in a cool, ventilated warehouse. Keep away from fire and heat. Packaging requirements sealed, not in contact with air.Should be stored separately with the base, avoid mixing reservoir. The storage area shall be provided with suitable material tocontain the spill.Caution:Phosphorous acid is a two inorganic acid corrosion products, the risk code number: 93014R22:Harmful if swallowed.R35:Causes severe burns.Detailed PhotosPhosphorous acid 98.5%Other name:Phosphonic acid; hydrogen phosphonate;phosphorus(+3) trihydride cation trihydroxideCAS No.:13598-36-2MF:H3PO3EINECS:237-066-7Appearance: colorless crystal powderMolecular weight: 82Density:1.651 g/cm3 (21 °C)Melting point:73.6 °C (164.5 °F; 346.8 K)Boiling point:200oC(392 °F; 473 K) (decomposes)Solubility in water: 310 g/100 mLApplication:Phosphate fertilizerClassification:Organic FertilizerUN number: 2834Quality Standard: HG/T 2520-93 CertificationsCompany ProfileOur Advantages Yunnan Litto Chemicals Corporation is a professional chemicals company which has deal with fine chemicals more than 20 years,the product such as plant hormones,organic fertilizer has been exported to more than 30 countries.
