Chaw tsim tshuaj paus zoo nqi phosphorous acid CAS: 13598-36-2

Cov lus piav qhia luv luv:

Phosphorous acid yog ib nrab nyob rau hauv kev npaj ntawm lwm cov duab phosphorous. Phosphorous acid yog cov khoom siv ua haujlwm los npaj phosphonates rau cov dej thiab kev tswj hwm kev sib cav, kev tswj hwm corrosion thiab corrosine ruaj khov. Lub alkali hlau ntsev (phosphites) ntawm phosphoration acid tau ua dav ua fungicers (piv txwv li qhov chaw tsis zoo ntawm cov nroj tsuag phosphoro. Phosphorous Acid yog siv nyob rau hauv stabilizing mixtures rau cov ntaub ntawv yas. Phosphorous Acid yog siv rau inhibling high-kub ntawm corrosion-nquag hlau cov npoo thiab los ua cov roj hlau thiab roj nplua nyeem thiab roj nplua nyeem.

Kev piav txog

Phosphorous acid, H3PO3, yog diprotic (nyeem tau ionizes ob tug protons), tsis yog triprotic li tej zaum yuav tau hais los ntawm cov mis no. Phosphorous acid yog ua nruab nrab hauv kev npaj ntawm lwm cov duab phosphorous. Vim tias kev npaj thiab siv ntawm "phosphorous acid" ua rau pom ntau dua rau cov tshuaj lom neeg H3piav ntxiv, nws yog qhov zoo tshaj plaws li HPO (Oh) 2 los qhia nws tus cwj pwm diprotic.

Txhais lus hais tias

Phosphorus trihydroxide; phosphorustrihydretras;

Trihydroxyphphphhphine; phosphorousacid, reagent;

Phosphonsure; phosphorous acid, 98%, ntxiv ntshiab; aurora ka-1076

Cov ntawv thov ntawm phosphorous acid

1.Posphorousor yog siv los tsim cov chiv phosphate ntsev li potassium phosphite, ammon calosphite thiab calosphite. 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.Phophorous acid (h3poogle, orthoposphorous acid) tej zaum yuav raug siv ua ib qho ntawm cov tshuaj tiv thaiv rau cov khoom siv 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.
