Iithegi zeMveliso

Hypophosphorous acid

I-CAS 6303-21-5

Iipropati zeMichiza

I-Hypophosphorous acid yi-arhente yokunciphisa.Eyomeleleyo monobasic acid.Isisombululo esinamanzi sinomuncu kwaye sinokuthi ngokuthe ngcembe sifakwe i-oxidized emoyeni kwiqondo lokushisa.Ukuqhagamshelana ne-H porogen kuya kubangela ukutshisa.Inokutsha ngokusabela ngobundlobongela kunye nee-oxidizing agents.Ukubolisa irhasi yephosphine enetyhefu kakhulu ngobushushu obuphezulu, nokugqabhuka.Eyothusayo.I-Hypophosphorous acid isoloko igalelwa kwiziselo ezipholileyo kuba ayifuntshwa.Ngoko ke umngcipheko umncinci, kodwa ngokukodwa i-hypophosphorous acid egxininisiweyo inokulimaza i-gastrointestinal tract.

Intshayelelo engundoqo

I-Hypophosphorous acid, ekwabizwa ngokuba yi "hypophosphorous acid", yioyile engenambala okanye ikristale epholileyo, kwaye iyimveliso ebalulekileyo yoshishino lweekhemikhali ezilungileyo.Injongo ephambili kukuba isetyenziswe njenge-arhente yokunciphisa i-electroless plating, ukuthintela ukuguquguquka kwe-phosphoric acid resin, kwaye ingasetyenziselwa njenge-catalyst kunye ne-refrigerant ye-esterification reaction, ngakumbi ukuveliswa kwe-hypophosphite ye-sodium ecocekileyo.Kukho iindlela ezininzi zokulungiselela, phakathi kwazo iindlela zokulungiselela eziqhelekileyo kwishishini ziquka indlela ye-ion exchange resin kunye ne-electrodialysis method.
