okunye

I-Hypophosphorous acid iyi-ejenti yokunciphisa.I-monobasic acid enamandla.Isixazululo se-aqueous sine-acidic futhi kancane kancane singakhipha i-oxidize emoyeni ekamelweni lokushisa.Ukuthintana ne-H eyenza izimbotshana kungabangela ukusha.Ukuvutha ngenxa yokusabela okunamandla ngama-oxidants.Igesi ye-Phosphine, enobuthi obukhulu ngenxa yokubola okushisayo, iyaqhuma.Okulimazayo.I-Hypophosphorous acid ivama ukungezwa eziphuzweni ezipholile ngoba ayimuncwa.Ngakho-ke ingozi incane, kodwa i-Hypophosphorous acid ene-concentration enamandla kakhulu izolimaza i-gastrointestinal tract.Ukushisisa i-asidi eqinile iye ku-130-140 ℃ kuholela ekwahlukaneni nokubola ibe yi-PH3 ne-H3PO4.

I-Hypophosphorous acid, eyaziwa nangokuthi "i-hypophosphite", i-crystal oil engenambala noma i-deliquescent, iwumkhiqizo obalulekile wemboni yamakhemikhali emihle.Isetshenziswa kakhulu njenge-ejenti yokunciphisa i-electroless plating ukuvimbela ukushintsha kombala kwe-phosphoric acid resin, kanye ne-catalyst kanye nesiqandisi sokusabela kwe-esterification, ikakhulukazi ukukhiqizwa kwe-high-purity Sodium hypophosphite.Ziningi izindlela zokulungiselela, phakathi kwazo izindlela ezijwayelekile zokulungiselela embonini i-ion exchange resin method kanye nendlela ye-Electrodialysis.

Isebenzisa

1. I-Hypophosphorous acid isetshenziswa njenge-ejenti yokunciphisa i-electroless plating;
2. Ingasetshenziselwa ukuvimbela ukushintsha kombala kwe-phosphoric acid resin;
3. Isetshenziswa njenge-esterification catalyst, isiqandisi;
4. Isetshenziselwa ukukhiqiza i-hypophosphite, usawoti we-sodium, usawoti we-manganese, usawoti wensimbi ngokuvamile usetshenziswa njengezinto ezinomsoco;
5. I-Hypophosphorous acid isetshenziswa kwezokwelapha futhi njenge-ejenti yokunciphisa, ukuzimisela kwe-arsenic, i-tellurium nokuhlukaniswa kwe-tantalum, i-niobium namanye ama-reagents.
6. I-ejenti yokunciphisa enamandla, Ingasetshenziselwa ukulungiswa kwe-sodium hypophosphite, i-calcium phosphate kanye nezinye i-hypophosphite.
7. Ingasetshenziselwa ukugeza okucwebezelayo.Ezemithi.i-ejenti yokunciphisa.ama-reagents ajwayelekile.
8. I-agent yokunciphisa enamandla, ingasetshenziswa ekwenzeni i-sodium hypophosphite, i-calcium phosphate kanye nenye i-hypophosphite.
9. Lo mkhiqizo usetshenziswa kabanzi njenge-ejenti yokunciphisa, i-Ag, i-Cu, i-Ni, i-Hg nezinye izinsimbi zincishiswa zibe yinsimbi ehambisanayo, ukuze kuqinisekiswe i-As, Nb, Ta a
