Phosphorous Acid, Ib qho inorganic compound nrog cov tshuaj lom neeg H3pula3. Nws yog cov hmoov dawb huv, yooj yim soluble hauv dej thiab ethanol, thiab maj mam oxidized rau hauv astophosphate hauv huab cua. Phosphite yog dibasic acid, nws acidity yog me ntsis muaj zog dua phosphoric acid, nws muaj peev xwm txo cov sulfuric acid los sulphuric dioxide. Nws muaj kev hygroscopicity muaj zog thiab kev sib luag, thiab yog corrosive. Phospite yog tsuas yog siv los ua txo tus neeg sawv cev, Nylon beatening tus neeg sawv cev, tshuaj lom neeg cov khoom sib xyaw thiab cov organic phosphorus dej ua kom cov ntaub ntawv raw.
Khoom:Dawb crystalline hmoov. Soluble hauv dej thiab dej cawv.Kev: 1.651g / cm3, melting point: 73 ℃, boiling taw tes: 200 ℃.
Daim ntawv thov:
1.Phosphorous Acidyog siv los tsim cov chiv phosphate ntsev li potassium phosphite, ammon calosphite thiab calcium phospepite. Nws yog nquag koom nrog kev npaj phosphites zoo li aminotris acid) (athrophosphonics acid) (1,2-tricarboxylic acid (PBTC), uas pom Daim ntawv thov hauv kev kho dej raws li nplai lossis xeb cov pa dej. Nws kuj yog siv rau hauv cov tshuaj lom neeg raws li tus neeg sawv cev txo nqi. Nws cov ntsev, cov tshuaj phosphite yog siv ua PVC stabilizer. Nws tseem raug siv los ua cov thawj coj ua ntej hauv kev npaj phosphine thiab raws li ib nrab hauv nruab nrab hauv kev npaj ntawm lwm yam phosphorus tebchaw.
2.Phosphorous Acid(H3PO3, orthophosphorous acid) yuav siv los ua ib qho ntawm cov tshuaj tiv thaiv rau cov hluavtaws ntawm cov hauv qab no:
α-aminomethylphosphonic acids ntawm mannich-hom multicomponent tshuaj tiv thaiv
1-aminoalkephaphonicsphonic acids ntawm amidoalkylation ua raws li los ntawm hydrolysis
N-tiv thaiv α-aminophosphonic acids (phospho-isospes ntawm ntuj amino acids) ntawm amidoalkylation cov neeg
3. Kev lag luam siv: Tus sau no tau tsim tsis ntev los no thiab tau siv feem ntau ntawm cov neeg sau nyiaj txiag, piv txwv li cassiterite, ilmenite thiab pyrofore). Tsawg heev yog paub txog kev ua haujlwm ntawm cov neeg sau no. Cov kev tshawb fawb tsis tshua muaj nrog cov cim nqaij ncauj lus thiab cov kab mob rutile thiab cov neeg sib xyaw ntawm cov neeg sau khoom ua kom zoo nkauj tab sis tau xaiv ntau.
Txujcial Ntau Lawm:
Muaj cov txheej txheem ntau lawm xws li Trichhloroic phosphorus thiab phosphoric acid ntsev. Cov tshuaj hydrolysis maj mam ntxiv rau dej rau cov tshuaj tiv thaiv hydrolysis ua raws li kev sib xyaw ntawm cov trickhloride kom tsim cov sub -phosphoric acid. Tom qab kho dua tshiab, cov tshuaj tawm txias, cov crystallization thiab disoloration yog ua, thiab cov khoom tiav tau ua. Nws pci3 + 3h2o → H3PLO3 + 3HCL ua tau hydrogen chloride rov ua dua tshiab thaum lub zog ntau lawm, uas tuaj yeem ua rau hauv hydrochloric acid.
Kev Ruaj Ntseg:
Cov kab mob flammability muaj kev pheej hmoo: Hauv H Qhov laj thawj ua ke; Tshav kub decomposes toxic phosphorus oxide fumes.
Cov khoom ntim thiab tsheb thauj mus los: tais cua sov cua kub qhuav; Khaws cais los ntawm h pore-tso tus neeg sawv cev thiab alkali.
Packing: 25kg / hnab
Cia: khaws cia hauv qhov chaw kaw zoo, lub teeb-tiv taus, thiab tiv thaiv los ntawm ya raws.
