Habka Wax-soo-saarka Kaalshiyamka

Kaalshiyam formate waa iskudhis kiimiko oo leh caanaha Ca(HCOO)2. Waxa lagu soo saaraa falcelin u dhaxaysa calcium hydroxide (Ca(OH)2) iyo formic acid (HCOOH). Halkan waxaa ah dulmar guud oo ku saabsan habka wax soo saarka ee qaabka calcium:

1. Diyaarinta Calcium Hydroxide:

• Calcium hydroxide, oo sidoo kale loo yaqaan lime slaked, waxaa caadi ahaan soo saara fuuq-celinta degdegga ah (calcium oxide).
• Quicklime marka hore waxaa lagu kululeeyaa foornada ilaa heerkul sare si looga saaro carbon dioxide, taasoo keentay sameynta calcium oxide.
• Kaalshiyam oxide ayaa markaa lagu qasaa biyo si loo soo saaro kaalshiyam hydroxide.

2. Diyaarinta Formic Acid:

• Aashitada Formic waxaa sida caadiga ah lagu soo saaraa oksaydhka methanol, iyadoo la isticmaalayo kicinta sida kicinta qalinka ama kicinta rhodium.
• Methanol waxaa lagu falceliyaa ogsijiin iyadoo ay jirto joogitaanka kicinta si loo soo saaro formic acid iyo biyo.
• Falcelinta waxa laga yaabaa in lagu sameeyo weelka reactor ee heerkulka la xakameeyey iyo xaaladaha cadaadiska.

3. Falcelinta Calcium Hydroxide ee leh Formic Acid:

• Weelka reactor-ka, xalalka kaalshiyamka hydroxide waxa lagu qasaa xal aashitada formic ee saamiga stoichiometric si loo soo saaro qaabka calcium.
• Dareen-celinta caadi ahaan waa heer-sare, waxaana laga yaabaa in heerkulka la xakameeyo si loo hagaajiyo heerka falcelinta iyo dhalidda.
• Qaabka kalsiyumku wuxuu u soo baxaa sidii mid adag, isku darka falcelinta ayaa laga yaabaa in la sifeeyo si loo kala saaro qaabka calcium adag iyo heerka dareeraha.

4. Crystallization iyo engejin:

• Qaabka adag ee calcium ee laga helay falcelinta waxa laga yaabaa in la marsiiyo tillaabo habayn dheeraad ah sida crystallization iyo engejinta si loo helo badeecada la rabo.
• Crystallization waxaa lagu gaari karaa in la qaboojiyo isku darka falcelinta ama lagu daro dareere si kor loogu qaado samaynta crystal.
• Kaalshiyamyada qaabka calcium ayaa markaa laga soocaa khamriga hooyada oo la qalajiyo si looga saaro qoyaanka haraaga ah.

5. Nadiifinta iyo Baakadaha:

• Qaabka kaalshiyamka qallalan waxaa laga yaabaa inuu maro tillaabooyin sifeyn si meesha looga saaro wasakhda loona hubiyo tayada alaabta.
• Qaabka kaalshiyamka la safeeyey ayaa markaa lagu dhex baakadeeyey weelal ama bacaha ku habboon kaydinta, gaadiidka, iyo qaybinta isticmaalayaasha dhamaadka ah.
• Tallaabooyinka xakamaynta tayada ayaa lafuliyaa inta lagu guda jiro habka wax soo saarka si loo hubiyo in badeecada ugu dambeysa ay buuxiso shuruudaha iyo shuruudaha sharciyeynta.

Gabagabo:

Soo saarista qaabka calciumku waxay ku lug leedahay falcelinta u dhaxaysa calcium hydroxide iyo formic acid si loo soo saaro xarun la doonayo. Nidaamkani wuxuu u baahan yahay in si taxadar leh loo xakameeyo xaaladaha falcelinta, stoichiometry, iyo tillaabooyinka sifaynta si loo gaaro nadiifnimo iyo wax-soo-saar sare oo alaabta. Qaabka Calcium waxaa loo isticmaalaa codsiyo kala duwan, oo ay ku jiraan wax lagu daro la taaban karo, wax lagu daro quudinta, iyo soo saarista hargaha iyo dunta.
