Chaw Tsim Khoom Zoo Nqe Phosphorous Acid CAS: 13598-36-2
Kev piav qhia
Cov kua qaub phosphorous, H3PO3, yog diprotic (yooj yim ionizes ob protons), tsis yog triprotic raws li cov qauv no yuav qhia. Cov kua qaub phosphorous yog ib qho nruab nrab hauv kev npaj lwm cov tshuaj phosphorous. Vim tias kev npaj thiab kev siv "phosphorous acid" yeej muaj feem cuam tshuam nrog cov tautomer tseem ceeb, phosphonic acid, nws feem ntau hu ua "phosphorous acid". Cov kua qaub phosphorous muaj cov mis tshuaj H3PO3, uas zoo tshaj plaws qhia ua HPO(OH)2 los qhia nws tus cwj pwm diprotic.

Cov ntawv thov ntawm Phosphorous Acid
1. Cov kua qaub phosphorous yog siv los tsim cov ntsev phosphate chiv xws li potassium phosphite, ammonium phosphite thiab calcium phosphite. Nws koom nrog kev npaj cov phosphites xws li aminotris (methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) thiab 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), uas pom daim ntawv thov hauv kev kho dej ua cov nplai lossis cov tshuaj tiv thaiv corrosive. Nws kuj tseem siv rau hauv cov tshuaj tiv thaiv ua tus neeg sawv cev txo qis. Nws cov ntsev, lead phosphite yog siv ua PVC stabilizer. Nws kuj tseem siv ua tus precursor hauv kev npaj phosphine thiab ua tus neeg nruab nrab hauv kev npaj lwm cov phosphorus compounds.
2. Phosphorous acid (H3PO3, orthophosphorous acid) yuav siv tau ua ib qho ntawm cov khoom siv rau kev tsim cov hauv qab no:
α-aminomethylphosphonic acids ntawm Mannich-Type Multicomponent Reaction
1-aminoalkanephosphonic acids ntawm amidoalkylation ua raws li hydrolysis
N-tiv thaiv α-aminophosphonic acids (phospho-isosteres ntawm cov amino acids ntuj) ntawm amidoalkylation reaction
3. Kev siv rau hauv kev lag luam: Cov khoom siv no tau tsim tsis ntev los no thiab siv ua cov khoom siv tshwj xeeb rau cassiterite los ntawm cov ores uas muaj cov khoom sib xyaw ua ke. Raws li cov phosphonic acid, Albright thiab Wilson tau tsim ntau yam khoom siv rau kev ua kom cov oxidic minerals (piv txwv li cassiterite, ilmenite thiab pyrochlore). Muaj tsawg heev uas paub txog kev ua tau zoo ntawm cov khoom siv no. Kev tshawb fawb tsawg tsawg uas tau ua nrog cassiterite thiab rutile ores qhia tau tias qee cov khoom siv no tsim cov npuas loj tab sis xaiv tau zoo heev.
