I-Hypophosphorous acid yi-arhente yokunciphisa.Eyomeleleyo monobasic acid.Isisombululo se-aqueous si-acidic kwaye sinokukhupha ngokuthe ngcembe emoyeni kwiqondo lokushisa.Ukudibana ne-H i-ejenti eyenza i-pore kunokubangela ukutsha.Ukutshisa ngenxa yokusabela okunzulu kunye nee-oxidants.Irhasi yePhosphine, enetyhefu kakhulu ngenxa yokubola okuphezulu kwe-thermal, ide iqhume.Eyothusayo.I-Hypophosphorous acid isoloko igalelwa kwiziselo ezipholileyo kuba ayifuntshwa.Ngoko ingozi incinci, kodwa i-Hypophosphorous acid ene-concentration enamandla kakhulu iya kulimaza i-gastrointestinal tract.Ukufudumeza i-asidi eqinileyo ukuya kwi-130-140 ℃ kubangela ukungalingani kunye nokubola kwi-PH3 kunye ne-H3PO4.

I-Hypophosphorous acid, ekwabizwa ngokuba yi "hypophosphite", i-oyile engenambala okanye i-deliquescent crystal, iyimveliso ebalulekileyo yoshishino lweekhemikhali ezilungileyo.Isetyenziswa kakhulu njenge-arhente yokunciphisa i-electroless plating ukuthintela ukujika kombala we-phosphoric acid resin, kunye ne-catalyst kunye ne-refrigerant yokusabela kwe-esterification, ngakumbi ukuveliswa kwe-Sodium hypophosphite ephezulu.Kukho iindlela ezininzi zokulungiselela, phakathi kwazo iindlela zokulungiselela eziqhelekileyo kwishishini i-ion exchange resin method kunye ne-Electrodialysis method.

Usebenzisa
