Chaw tsim tshuaj paus Zoo Nqe Phosphorous Acid CAS: 13598-36-2

1. Phosphorous acid yog siv los tsim cov chiv phosphate ntsev xws li potassium phosphite, ammonium phosphite thiab calcium phosphite. Nws nquag koom nrog hauv kev npaj cov phosphites zoo 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 raws li qhov ntsuas lossis corrosive. Nws kuj yog siv nyob rau hauv cov tshuaj tiv thaiv raws li ib tug txo tus neeg sawv cev. Nws cov ntsev, txhuas phosphite yog siv los ua PVC stabilizer. Nws kuj yog siv los ua ib qho precursor hauv kev npaj ntawm phosphine thiab ua ib qho nruab nrab hauv kev npaj ntawm lwm cov phosphorus compounds.
2.Phosphorous acid (H3PO3, orthophosphorous acid) yuav siv tau los ua ib qho ntawm cov tshuaj tiv thaiv rau cov synthesis ntawm 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 natural amino acids) ntawm amidoalkylation cov tshuaj tiv thaiv
3. Muaj kev siv ： Cov khoom siv no tau tsim los tsis ntev los no thiab tau siv feem ntau los ua cov khoom tshwj xeeb rau cov cassiterite los ntawm cov ores nrog cov kab mob sib luag.Rau lub hauv paus ntawm phosphonic acid, Albright thiab Wilson tau tsim ntau yam ntawm cov khoom siv feem ntau rau flotation ntawm oxidic minerals (xws li cassiterite, ilmenite thiab pyrochlore). Tsis tshua muaj neeg paub txog kev ua tau zoo ntawm cov khoom siv no. Cov kev tshawb fawb txwv ua nrog cassiterite thiab rutile ores tau pom tias qee qhov ntawm cov khoom siv no tsim cov voluminous froth tab sis xaiv heev.
