I-calcium yakha inqubo yokukhiqiza

I-calcium yakha yindawo yamakhemikhali ngefomula ca (HCOO) 2. Kukhiqizwa ngokusabela phakathi kweCalcium Hydroxide (CA (OH) 2) ne-Formic Acid (HCOOH). Nakhu ukubuka konke okujwayelekile kwenqubo yokukhiqiza ye-calcium yakha:

1. Ukulungiselela i-calcium hydroxide:

• I-calcium hydroxide, eyaziwa nangokuthi i-slime lime, ivame ukukhiqizwa yi-hydration ye-Quicklime (calcium oxide).
• I-Quicklime iqala ukufuthelwa ku-kiln kuya emazingeni okushisa aphezulu ukushayela i-carbon dioxide, okuholela ekwakhekeni kwe-calcium oxide.
• I-calcium oxide ihlanganiswa namanzi kwinqubo elawulwa ukukhiqiza i-calcium hydroxide.

2. Ukulungiselela i-achi acid:

• I-formic acid ikhiqizwa ngokujwayelekile nge-oxidation ye-methanol, isebenzisa i-catalyst efana nesiliva catalyst noma i-rhodium catalyst.
• I-Methanol ibhekwa nge-oksijini phambi kweCatalyst ukukhiqiza i-acid namanzi.
• Ukuphendula kungenzeka kwenziwe emgodini wokuphendula ngaphansi kwezimo zokushisa ezilawulwayo nezimo zokucindezela.

3. Ukusabela kwe-calcium hydroxide nge-formic acid:

• Esitsheni sokuphendula, isixazululo se-calcium hydroxide sixutshwe nesixazululo se-formic acid kusilinganiso se-stoichiometric ukukhiqiza i-calcium yakha.
• Ukuphendula ngokujwayelekile, futhi izinga lokushisa lingalawulwa ukuze lisebenzise isilinganiso sokuphendula nesivuno.
• I-calcium yakha ama-precipitates njenge-solid, futhi ingxube yokusabela ingahlungwa ukuze ihlukanise i-calcium eqinile eyakha esigabeni se-liquid.

4. I-Crystallization nokomisa:

• I-SOLIGAL CALCISIM eqinile etholwe ekuphenduleni ingahle ibhekane nezinye izinyathelo zokucubungula ezifana ne-crystallization kanye nokomisa ukuthola umkhiqizo owufunayo.
• I-Crystallization ingahle itholakale ngokupholisa ingxube yokusabela noma ngokungeza i-solvent ukukhuthaza ukwakheka kwe-crystal.
• Amakristalu e-calcium asungulwa ahlukaniswe notshwala bamama futhi bomile ukususa umswakama osele.

5. Ukuhlanza nokupakisha:

• I-calcium eyomisiwe eyakha ingahle ibhekane nezinyathelo zokuhlanzwa ukususa ukungcola futhi kuqinisekise ikhwalithi yomkhiqizo.
• I-calcium ehlanziwe yasungulwa ifakwe ezitsheni ezifanele noma izikhwama zokugcina, zokuhamba, kanye nokusatshalaliswa kubasebenzisi bokugcina.
• Izindlela zokulawula ezisezingeni elifanele zenziwa kuyo yonke inqubo yokukhiqiza ukuze uqinisekise ukuthi umkhiqizo wokugcina uhlangabezana nokucaciswa kanye nezidingo zokulawula.

Isiphetho:

Ukukhiqizwa kwe-calcium okwakheka kufaka phakathi ukusabela phakathi kwe-calcium hydroxide ne-formic acid ukukhiqiza i-compand oyifunayo. Le nqubo idinga ukulawula ngokucophelela kwezimo zokuphendula, amaStoichiometry, nezinyathelo zokuhlanza ukuze kufinyelelwe ubumsulwa bomkhiqizo obuphezulu kanye nesivuno. I-calcium yakha isetshenziswa ezinhlelweni ezahlukahlukene, kufaka phakathi isengezo sikakhonkolo, isengezo sokuphakelayo, nasekukhiqizweni kwesikhumba nezindwangu.
