Sodium Sulfide CAS 1313-82-2

Sodium sulfide yog cov tshuaj sib xyaw nrog cov mis Na₂S, lossis ntau dua nws cov hydrate Na₂S·9H₂O. Ob leeg yog dej tsis muaj xim -soluble ntsev uas muab cov tshuaj alkaline zoo heev. Thaum raug huab cua ntub, Na₂S thiab nws cov hydrates emit hydrogen sulfide, uas tsw zoo li lub qe lwj Sodium sulfide, anhydrous yog daj rau cib liab crystalline loj los yog fused khoom. Yog tias raug huab cua ntub, nws nqus dej noo los ntawm huab cua, thiab nws yuav tsum tau ua kom muaj cua sov tsis tu ncua thiab tuaj yeem ua rau hluav taws kub ntawm cov khoom siv hluav taws xob nyob ze. Kev lag luam sodium sulfide feem ntau nthuav tawm cov xim liab, xim liab los yog xim daj daj xim rau muaj cov impurities.

Kev siv Sodium Sulfide

Cov dej aqueous nthuav tawm muaj zog alkalinity thiab corrosive ntawm tooj liab, ntoo, tawv nqaij, thiab lwm yam. Nws yog me ntsis soluble hauv ethanol, tab sis insoluble hauv ether. Thaum ntsib cov kua qaub muaj zog, sodium sulfide yuav tso tawm hydrogen sulfide. Nws yuav raug deliquescence hauv huab cua thiab yooj yim oxidized rau hauv sodium thiosulfate. Sodium sulfide feem ntau yog siv los ua cov ntaub ntawv raw ntawm hides depilatories, pulp ua tus neeg sawv cev, thiab leej faj zas xim, txo cov neeg ua haujlwm ntawm cov xim nruab nrab, cov ntaub dyeing mordant, thiab ore flotation tus neeg saib xyuas. Nws kuj tseem siv tau los ua viscose fiber ntau desulfurizer thiab cov khoom siv raw rau kev tsim cov sodium hydrosulfide thiab sodium polysulfide.

Raws li sodium sulfide yog siv nyob rau hauv textile dyeing thiab xov, nws yuav siv tau raws li ib tug bleaching neeg sawv cev, ua lwm txoj rau sodium chlorite thiab hydrogen peroxide. Nws tshem tawm yellowish stains thiab me ntsis uas tsis raug tshem tawm los ntawm txheej txheem laundering. Sodium sulfide kuj tseem siv tau los ua desulfurizing thiab dechlorinating tus neeg sawv cev thaum cuam tshuam nrog cov ntaub ntawv tawv. Tsis tas li ntawd, nws yog siv kom tau txais sulfur dub dyes, uas tuaj yeem kho thiab ua tiav kom tau txais lwm cov xim dyes.

Nws yog feem ntau siv hauv kev lag luam pulp thiab ntawv hauv cov txheej txheem Kraft ntawm kev tsim cov ntawv. Nws yog ib feem ntawm cov cawv dawb ntxiv rau sodium hydroxide, thiab cawv dawb ua lub luag haujlwm tseem ceeb hauv kev tsim cov ntoo pulp. Nws yog koom nrog hauv thawj theem ntawm cov txheej txheem Kraft lossis cov kauj ruam impregnation qhov twg cov ntoo chips yog impregnated nrog cov cawv dawb.

Nws yog siv rau hauv cov txheej txheem kho dej los pab tshem tawm cov hlau impurities los ntawm mining - cuam tshuam - dej thaum kho. Sodium sulfide kuj tseem siv hauv kev tsim tshuaj raws li sulfonation thiab sulfomethylation tus neeg sawv cev. Ntxiv rau qhov ntawd, nws yog siv rau hauv kev lag luam kev yees duab los tiv thaiv thiab tiv thaiv tus tsim tawm los ntawm oxidation. Sodium sulfide kuj tseem siv rau hauv kev lag luam tawv. Nws yog siv los ua ib qho ntawm cov reagents kom tshem tawm cov plaub hau los ntawm qhov nkaum thiab siv rau hauv tanning ntawm cov tawv nqaij tsiaj los ua tawv. Cov txheej txheem unhairing yog siv nyob rau hauv lub txiv qaub ua hauj lwm, qhov twg nkaum yog soaked nyob rau hauv ib tug alkaline tov
