Inqubo Yokukhiqiza I-Calcium Formate

I-calcium formate iyinhlanganisela yamakhemikhali enefomula ethi Ca(HCOO)2. Ikhiqizwa ngokusabela phakathi kwe-calcium hydroxide (Ca(OH)2) ne-formic acid (HCOOH). Nakhu ukubuka konke okujwayelekile kwenqubo yokukhiqiza ye-calcium formate:

1. Ukulungiswa kweCalcium Hydrooxide:

• I-calcium hydroxide, eyaziwa nangokuthi i-slaked lime, ivame ukukhiqizwa ukugeleza kwe-quicklime (i-calcium oxide).
• I-Quicklime iqala ukushiswa kuhhavini kuya kumazinga okushisa aphezulu ukuze ikhiphe isikhutha, okuholela ekwakhekeni kwe-calcium oxide.
• I-calcium oxide ibe isihlanganiswa namanzi ngenqubo elawulwayo ukuze kukhiqizwe i-calcium hydroxide.

2. Ukulungiswa kwe-Formic Acid:

• I-Formic acid ivame ukukhiqizwa nge-oxidation ye-methanol, kusetshenziswa i-catalyst efana ne-silver catalyst noma i-rhodium catalyst.
• I-Methanol isabela nge-oxygen phambi kwe-catalyst ukukhiqiza i-formic acid namanzi.
• Ukusabela kungase kwenziwe emkhunjini we-reactor ngaphansi kwezimo zokushisa ezilawulwayo nezingcindezi.

3. Ukusabela kweCalcium Hydroxide nge-Formic Acid:

• Emkhunjini we-reactor, isixazululo se-calcium hydroxide sixutshwa nesisombululo se-formic acid ngesilinganiso se-stoichiometric ukukhiqiza i-calcium formate.
• Ukusabela kuvamise ukuba yi-exothermic, futhi izinga lokushisa lingalawulwa ukuze kuthuthukiswe izinga lokusabela kanye nesivuno.
• I-calcium formate iphuma njengeqinile, futhi ingxube yokusabela ingase ihlungwe ukuze kuhlukaniswe i-calcium formate eqinile nesigaba soketshezi.

4. I-Crystallization kanye Nokomisa:

• I-calcium formate eqinile etholwe ekuphenduleni ingase ibhekane nezinyathelo zokucubungula ezengeziwe ezifana nokucwebezela kanye nokomiswa ukuze kutholwe umkhiqizo owufunayo.
• I-Crystallization ingafinyelelwa ngokupholisa ingxube yokusabela noma ngokungeza isincibilikisi ukuze kuthuthukiswe ukwakheka kwekristalu.
• Amakristalu e-calcium formate abe esehlukaniswa notshwala kamama bese omiswa ukuze kukhishwe umswakama osele.

5. Ukuhlanzwa kanye Nokupakishwa:

• I-calcium formate eyomisiwe ingase ithathe izinyathelo zokuhlanza ukuze isuse ukungcola futhi iqinisekise ikhwalithi yomkhiqizo.
• I-calcium formate ehlanzekile ibe isipakishwa ezitsheni noma ezikhwameni ezifanele ukuze zigcinwe, zihanjiswe, futhi zihanjiswe kubasebenzisi bokugcina.
• Izinyathelo zokulawula ikhwalithi zisetshenziswa kuyo yonke inqubo yokukhiqiza ukuze kuqinisekiswe ukuthi umkhiqizo wokugcina uhlangabezana nemibandela nezidingo zokulawula.

Isiphetho:

Ukukhiqizwa kwe-calcium formate kuhilela ukusabela phakathi kwe-calcium hydroxide ne-formic acid ukukhiqiza isakhi esidingekayo. Le nqubo idinga ukulawula ngokucophelela izimo zokusabela, i-stoichiometry, nezinyathelo zokuhlanza ukuze kuzuzwe ubumsulwa bomkhiqizo ophezulu kanye nesivuno. I-calcium Formate isetshenziswa ezinhlelweni ezahlukahlukene, kufaka phakathi njengesengezo sikakhonkolo, isithasiselo sokuphakelayo, nasekukhiqizeni isikhumba nezindwangu.
