Ziziphi iipropati kunye nokusetyenziswa okuphambili kwe-rongalite?

Igama: Isodium formaldehyde sulfoxylate;Izigaqa zeRongalite C;I-Rongalite dihydrate;

Isodium bisulfoxylate formaldehyde;sodium hydroxymethane sulfinate

Ifomula yemolekyuli:NaHSO2-CH2O-2H2O

CAS No.:149-44-0/6035-47-8

Iipropati:Ikwabizwa ngokuba yi-sodium formaldehyde bisulfate (rongalite).

I-Rongalite powder translucent white rhombohedral crystals okanye amaqhekeza amancinci.

Ubuninzi obubonakalayo 1.80-1.85g / cm3. indawo yokunyibilika 64℃ (inyibilike emanzini ayo ayikristale). Ibola ngaphezulu kwe-120°C.

Inyibilika ngokukhululekileyo emanzini, inyibilika kancinane etywaleni.

Ityuwa ye-anhydrous izinzile ngakumbi. Noko ke, ngokuthe ngcembe ibola kumoya ofumileyo. Ukunciphisa kakhulu kumaqondo aphezulu.

Indlela yemveli yokuvelisa i-rongalite powder iqukethe i-zinc powder kunye namanzi ukwenza i-slurry,

dlula kwi-sulphur dioxide ukuze uphendule ukuvelisa i-dithionite ye-zinc, uze udibanise i-formaldehyde,

i-zinc powder ukunciphisa kwaye emva koko isabela nge-sodium hydroxide ukuvelisa.

Indlela entsha yokuvelisa inyathelo elinye isebenzisa i-sodium metabisulphite njengento ekrwada

kwaye igqitywe kwinqanaba elinye ngokunciphisa i-zinc powder kunye nokongezwa kwe-formaldehyde.

Isetyenziswa njengearhente yomzobo kunye nearhente yokunciphisa ukuprinta kunye nokudaya,

ukudibanisa irabha, ukuveliswa kweswekile,

ukuveliswa kwedayi ye-indigo kunye nokunciphisa idayi.

I-sodium formaldehyde sulfoxylate ethengiswa yiRongda Chemical iveliswa ngokusebenzisa inkqubo entsha.

Ngolu ncedo lulandelayo:

umxholo ophantsi wentsimbi enzima

zibonelela ngeyona nkonzo ilungileyo emva kokuthengisa

isidima esiphezulu kwintsimi yeekhemikhali
