Isicelo kanye nokuthuthukiswa kwenqubo ye-sodium formaldehyde sulfoxylate

Isikhathi: 2021-07-09 Ukushaya: 211

I-Sodium sulfoxylate formaldehyde (NaHSO2 · CH2O · 2H2O),

Eyaziwa nangokuthi i-assodium formaldehyde sulfoxylate,

Igama lempahla:Rongalite C.

Kuyibhulokhi emhlophe ekhanyayo enephuzu lokuncibilika elingu-64 ℃. Inokuncipha okuqinile emazingeni okushisa aphezulu futhi ingafiphala izindwangu ezidayiwe.

Ngakho-ke, isetshenziswa kakhulu njenge-ejenti yokukhipha embonini yokunyathelisa nokudaya, njenge-ejenti yokuxubha embonini ye-raber synthesis kanye noshukela.

Ngokuthuthukiswa nokusetshenziswa kwemikhiqizo, eminyakeni yamuva nje, ibisetshenziswa nasembonini yensipho kanye nokwelashwa kwezokwelapha njengekhambi le-Hg, Bi, Ba.

Ukukhiqizwa kwe-rongalite ngokuvamile kusebenzisa indlela yendabuko enezinyathelo ezintathu, okuyi-zinc powder-sulphur dioxide-formaldehyde method.

Okungukuthi, i-sulphur dioxide, i-zinc powder, ne-formaldehyde isetshenziswa njengezinto zokusetshenziswa, futhi i-sulfur dioxide ne-zinc powder isabela ekwakheni i-zinc dithionite (ZnS2O4), bese i-formaldehyde eyengeziwe, ukunciphisa i-zinc powder kanye ne-sodium hydroxide metathesis reaction yokwenza umkhiqizo.

Ukukhiqizwa kwe-domeryrongalite nakho kusebenzisa imisebenzi yezandla yendabuko eshiwo ngenhla. Imikhiqizo ihlinzekwa kakhulu emakethe yasekhaya, kanti eminye ithunyelwa eNingizimu-mpumalanga ye-Asia.

Esikwethula inqubo entsha , okungukuthi, inqubo yokuthola umkhiqizo ku-sodium metabisulfite njengento eluhlaza ngokunciphisa i-zinc powder kanye nokwengezwa kwe-formaldehyde ngesinyathelo esisodwa.

Izinto zokusetshenziswa ziyancishiswa futhi zengezwe kugedlela elifanayo, futhi wonke ama-reactants aguqulwa abe yimikhiqizo, futhi akukho mfucuza.

Ngaphezu kwemikhiqizo eyinhloko, iphinde ikhiqize imikhiqizo ehlanzekile ye-zinc oxide (99.5%).

Inqubo inezici zenqubo emfushane, izimo zobuchwepheshe ezizinzile, utshalomali lwemishini ephansi kanye nokusebenza okulula.

Esihlokweni esilandelayo, ngizokwabelana ngenqubo yokukhiqiza ehlobene ne-sodium formaldehyde sulfoxylate.


Xhumana nathi

Sijoyine futhi ube owokuqala ukwazi ngemikhiqizo yethu yakamuva kanye nokukhushulwa.
