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-kuleyl, heerkulkana waxaa laga yaabaa in la xakameeyo si loo hagaajiyo heerka falcelinta iyo dhalidda.
• Qaabka kalsiyumku wuxuu u soo baxaa sidii mid adag, isku darka falcelinta waxaa 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 nadiifnimada iyo wax-soo-saarka badeecada sare.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.
