Chemical Properties

I-Hypophosphorous acid iyi-ejenti yokunciphisa.I-monobasic acid enamandla.Isixazululo esinamanzi sine-asidi futhi singafakwa i-oxidized kancane kancane emoyeni ekamelweni lokushisa.Ukuthintana ne-H porogen kuzodala ukushisa.Ivutha ukusabela okunodlame ngama-oxidizing agents.Bolisa igesi ye-phosphine enobuthi kakhulu ngokushisa okuphezulu, ngisho nokuqhuma.Okulimazayo.I-Hypophosphorous acid ivama ukungezwa eziphuzweni ezipholile ngoba ayimuncwa.Ngakho-ke ingozi incane, kodwa ikakhulukazi i-hypophosphorous acid egxilile ingalimaza umgudu wamathumbu.

Isethulo Esiyinhloko

I-Hypophosphorous acid, eyaziwa nangokuthi "i-hypophosphorous acid", ingamafutha angenambala noma i-deliquescent crystal, futhi iwumkhiqizo obalulekile wemboni yamakhemikhali emihle.Inhloso eyinhloko kufanele isetshenziswe njenge-ejenti yokunciphisa i-electroless plating, ukuvimbela ukuguquguquka kwe-phosphoric acid resin, futhi ingasetshenziswa njenge-catalyst kanye nesiqandisi sokusabela kwe-esterification, ikakhulukazi ukukhiqizwa kwe-high-purity sodium hypophosphite.Kunezindlela eziningi zokulungiselela, phakathi kwazo izindlela ezijwayelekile zokulungiselela embonini zihlanganisa indlela ye-ion exchange resin kanye nendlela ye-electrodialysis.

Ukusetshenziswa:

1. Njenge-ejenti yokunciphisa yokucwenga ngamakhemikhali;
2. Isetshenziselwa ukuvimbela ukushintsha umbala kwe-phosphoric acid resin;
3. Isetshenziswa njenge-catalyst ye-esterification kanye nesiqandisi;
4. Isetshenziselwa ukwenza i-hypophosphite, futhi usawoti wayo we-sodium, usawoti we-manganese, usawoti wensimbi, njll. kuvame ukusetshenziswa njengezidakamizwa ezinomsoco;
5. Isetshenziswa kwezokwelapha futhi njenge-ejenti yokunciphisa, ama-reagents okunquma i-arsenic, i-tellurium nokuhlukanisa i-tantalum ne-niobium.
