Habka Waxtarka leh ee Sodium Hydrosulfide Synthesis Isticmaalka Kaarboonka Strontium

Sodium sulfide iyo Sodium hydrosulfide waa laba badeeco oo lagu helay habka nuugista alkaline ee lagu daweeyo gaaska qashinka warshadaha ee ammonia. Sodium sulfide iyo sodium hydrosulfide labaduba waxay leeyihiin codsiyo ballaaran. Sodium sulfide waxaa loo isticmaali karaa warshadaha dheeha si loo soo saaro midabada baaruudka, warshadaha birta aan birta ahayn sida wakiilka sabeynta ee macdanta, warshadaha maqaarka sida wakiilka nadiifinta timaha ee maqaarka cayriin, iyo warshadaha warqadda sida wakiilka karinta ee warqadda. Sodium hydrosulfide waxaa loo isticmaali karaa warshadaha rinjiga si loo sameeyo dhexdhexaadiyeyaasha dabiiciga ah, warshadaha maqaarka si loo nadiifiyo timaha loona mariyo maqaarka cayriin, iyo warshadaha bacriminta si looga saaro monomer sulfur-ka firfircoon Carbon kuwa wax ka saara sulfurizer-ka.

Sodium hydrosulfide waa nooc cusub oo walxo kiimiko ah oo la sameeyay kadib sodium sulfide, waxayna inta badan u jirtaa sida HS⁻ ions ee biyaha. Xalka aqueous wuxuu leeyahay alkalinity hoose marka loo eego sodium sulfide, waxayna muujisaa waxqabadka codsiga sare ee warshadaha iftiinka, warshadaha kiimikada, iyo meelaha kale. Tusaale ahaan, waxa loo isticmaalaa sida walxo ceeriin ah oo lagu soo saaro ammonium sulfide iyo ethyl mercaptan; warshadaha macdanta, waxaa si weyn loo isticmaalaa in ka faa'iidaysiga macdanta copper.

Waqtigan xaadirka ah, ganacsiyada intooda badani waxay ku shaqeeyaan ururinta gaaska hydrogen sulfide iyo carbon dioxide ee la dhaliyo inta lagu jiro diyaarinta strontium carbonate, hubinta in gaaska hydrogen sulfide iyo carbon dioxide ay leeyihiin xoogaa uruurin iyo cadaadis ka hor inta aan la gelin xalalka alkaline ee falcelinta. Tani waxay ka dhigan tahay in hababka diyaarinta ee strontium carbonate iyo sodium hydrosulfide ay kala duwan yihiin, ka hor diyaarinta sodium hydrosulfide, shaqaaluhu waxay u baahan yihiin inay qabtaan tillaabooyin dhexdhexaad ah oo dhexdhexaad ah iyo samaynta, taasoo ka dhigaysa habka diyaarinta mid adag.

Tillaabooyinka Geedi socodka Wax-soo-saarka

1. Xalka aqueous sodium sulfide waxaa lagu dhex geliyaa munaaradda falcelinta ugu horreysa iyada oo loo marayo munaaradda soo kabashada carbon dioxide, iyo kaarboon dioxide ayaa sidoo kale la soo galiyaa munaaradda falcelinta ugu horreysa, halkaas oo xalka aqueous sodium sulfide iyo carbon dioxide ay falcelinayaan.

2. Talaabada (1), kaarboonaysiinta strontium ee ka dhalatay, gaaska hydrogen sulfide ee soo saaray, iyo kaarboon laba ogsaydh oo aan falcelin ah ayaa laga soo ururiyay oo dib looga soo saaray munaaraddii falcelinta ugu horeysay ee munaaradda soo kabashada carbon dioxide. Kaarboon-dioxide-ka aan la falcelinin waxa uu la falgalaa xal-u-sodiyam sulfide aqueous ee munaaradda soo kabashada carbon dioxide, halka gaaska hydrogen sulfide uu galo munaaradda falcelinta labaad iyada oo loo marayo munaaradda soo kabashada carbon dioxide.

3. Sodium hydroxide xalalka alkaline waxaa lagu soo bandhigay munaaradda labaad ee falcelinta iyada oo loo marayo munaaradda soo kabashada hydrogen sulfide, halkaas oo gaaska hydrogen sulfide uu la falgalo xalka sodium hydroxide alkaline ee munaaradda labaad ee falcelinta.

4. Badeecada sodium hydrosulfide ee laga bilaabo tallaabada (3) ayaa la soo ururiyaa, gaaska hydrogen sulfide ee aan la falgelin ayaa dib loogu soo celinayaa munaaradda soo kabashada ee hydrogen sulfide si ay uga jawaabto xalalka alkaline sodium hydroxide.

Marka la soo koobo, habkani wuxuu si isdaba joog ah u soo saari karaa strontium carbonate iyo sodium hydrosulfide, taasoo muujinaysa sii socoshada habka wanaagsan iyo gaaritaanka dib-u-warshadaynta alaabta iyo alaabta ceeriin. Intaa waxaa dheer, habkani wuxuu fududeeyaa diyaarinta sodium hydrosulfide iyadoo la dhimayo baahida loo qabo tillaabooyinka diyaarinta iyo maaraynta dhexdhexaadka ah. Intaa waxaa dheer, waxay si wax ku ool ah u nuugtaa carbon dioxide iyo hydrogen sulfide gaaska, ka hortagga hydrogen sulfide in lagu sii daayo jawiga oo keena wasakhowga hawada.
