Zoo Nqe Loj Tshuag Hypophosphorous acid CAS 6303-21-5 Colorless Liquid
Chemical Properties
Hypophosphorous acid yog ib qho kev txo qis.Muaj zog monobasic acid.Cov tshuaj aqueous yog acidic thiab tuaj yeem maj mam oxidized hauv huab cua ntawm chav tsev kub.Kev sib cuag nrog H porogen yuav ua rau kub hnyiab.Combustible los ntawm nruj cov tshuaj tiv thaiv nrog oxidizing agents.Decompose heev phosphine roj los ntawm kub kub, txawm tawg.Corrosive.Hypophosphorous acid feem ntau ntxiv rau cov dej txias vim nws tsis nqus.Yog li qhov kev pheej hmoo me me, tab sis tshwj xeeb yog cov concentrated hypophosphorous acid tuaj yeem ua mob rau lub plab zom mov.
Main Qhia
Hypophosphorous acid, tseem hu ua "hypophosphorous acid", yog cov roj tsis muaj xim los yog deliquescent crystal, thiab yog ib qho tseem ceeb ntawm cov khoom lag luam zoo.Lub hom phiaj tseem ceeb yog siv los ua tus neeg sawv cev txo qis rau electroless plating, los tiv thaiv cov xim ntawm phosphoric acid resin, thiab nws kuj tseem siv tau los ua cov khoom siv hluav taws xob thiab cov tub yees rau cov tshuaj tiv thaiv esterification, tshwj xeeb tshaj yog rau kev tsim cov high-purity sodium hypophosphite.Muaj ntau txoj hauv kev npaj, ntawm cov txheej txheem kev npaj ntau hauv kev lag luam suav nrog ion exchange resin method thiab electrodialysis method.
Qee yam ntawm kuv cov khoom tshwm sim
Kev siv:
1. Raws li tus neeg sawv cev txo cov tshuaj plating;
2. Siv los tiv thaiv cov xim ntawm phosphoric acid resin;
3. Siv los ua catalyst rau esterification thiab cov tub yees;
4. Nws yog siv los ua hypophosphite, thiab nws cov ntsev ntsev, manganese ntsev, hlau ntsev, thiab lwm yam. feem ntau yog siv los ua tshuaj noj;
5. Siv nyob rau hauv cov tshuaj thiab raws li ib tug txo tus neeg sawv cev, reagents rau txiav txim arsenic, tellurium thiab cais tantalum thiab niobium.
