Inkqubo yeCalcium Formate Production

I-calcium fomati yikhemikhali ene-formula ethi Ca(HCOO)2. Iveliswa ngokusabela phakathi kwe-calcium hydroxide (Ca (OH) 2) kunye ne-formic acid (HCOOH). Nantsi inkcazo jikelele yenkqubo yemveliso ye-calcium formate:

1. Ukulungiswa kweCalcium Hydroxide:

• I-calcium hydroxide, ekwabizwa ngokuba yi-slaked lime, idla ngokuveliswa yi-hydration ye-quicklime (i-calcium oxide).
• I-Quicklime iqala ukufudumeza kwi-oven ukuya kumaqondo aphezulu okushisa ukukhupha i-carbon dioxide, okubangela ukubunjwa kwe-calcium oxide.
• I-calcium oxide iye ixutywe namanzi kwinkqubo elawulwayo ukuvelisa i-calcium hydroxide.

2. Ukulungiswa kweFormic Acid:

• I-asidi ye-Formic iveliswa nge-oxidation ye-methanol, isebenzisa i-catalyst efana ne-catalyst yesilivere okanye i-rhodium catalyst.
• I-Methanol isabela nge-oksijini phambi kwe-catalyst ukuvelisa i-asidi ye-formic kunye namanzi.
• Ukusabela kunokwenziwa kwinqanawa ye-reactor phantsi kobushushu obulawulwayo kunye neemeko zoxinzelelo.

3. Ukusabela kweCalcium Hydroxide ngeFormic Acid:

• Kwisitya se-reactor, isisombululo se-calcium hydroxide sixutywe kunye nesisombululo se-asidi ye-formic kumlinganiselo we-stoichiometric ukuvelisa i-calcium formate.
• Indlela abasabela ngayo idla ngokuba yi-exothermic, kwaye ubushushu bunokulawulwa ukunyusa izinga lokusabela kunye nesivuno.
• I-calcium fomati iphuma njengeqinileyo, kwaye umxube wokusabela unokuhluzwa ukwahlula i-calcium fomati eqinileyo kwisigaba solwelo.

4. ICrystallization kunye nokomisa:

• Ifomati ye-calcium eqinileyo efunyenwe kwi-reaction inokuqhubela phambili amanyathelo okucubungula afana necrystallization kunye nokomisa ukufumana imveliso efunekayo.
• I-Crystallization inokufezekiswa ngokupholisa umxube wokuphendula okanye ngokudibanisa i-solvent ukukhuthaza ukubunjwa kwekristale.
• Iikristale ze-calcium formate ziye zohlulwe kutywala benina zomiswe ukuze kususwe ukufuma okushiyekileyo.

5. Ukucoca kunye nokuPakisha:

• Ifomati ye-calcium eyomileyo inokuthatha amanyathelo okucoca ukususa ukungcola kunye nokuqinisekisa umgangatho wemveliso.
• I-calcium fomati ecocekileyo ifakwe kwiibhotile ezifanelekileyo okanye iingxowa zokugcina, ukuthutha, kunye nokuhanjiswa kubasebenzisi bokugqibela.
• Amanyathelo okulawula umgangatho aphunyezwa kuyo yonke inkqubo yokuvelisa ukuqinisekisa ukuba imveliso yokugqibela ihlangabezana neenkcukacha kunye neemfuno zokulawula.

Isiphelo:

Ukuveliswa kwefomati ye-calcium kubandakanya ukusabela phakathi kwe-calcium hydroxide kunye ne-asidi ye-formic ukuvelisa i-compound efunwayo. Le nkqubo ifuna ulawulo olucokisekileyo lweemeko zokusabela, i-stoichiometry, kunye namanyathelo okucoca ukufezekisa ubunyulu bemveliso ephezulu kunye nesivuno. I-calcium formate isetyenziswa kwizicelo ezahlukeneyo, kubandakanywa njenge-concrete additive, i-feed additive, kunye nokuveliswa kwesikhumba kunye namalaphu.
