Inkqubo yokuvelisa iCalcium Formate

I-Calcium formate yikhemikhali enefomyula i-Ca(HCOO)2. Yenziwa ngempendulo phakathi kwe-calcium hydroxide (Ca(OH)2) kunye ne-formic acid (HCOOH). Nantsi ingcaciso ngokubanzi yenkqubo yokuvelisa i-calcium formate:

1. Ukulungiswa kweCalcium Hydroxide:

• I-calcium hydroxide, ekwaziwa ngokuba yi-slaked lime, idla ngokuveliswa yi-hydration ye-quicklime (i-calcium oxide).
• IQuicklime ifudunyezwa kuqala kwi-oven ukuya kumaqondo obushushu aphezulu ukuze ikhuphe i-carbon dioxide, nto leyo ebangela ukwakheka kwe-calcium oxide.
• Emva koko i-calcium oxide ixutywa namanzi kwinkqubo elawulwayo ukuvelisa i-calcium hydroxide.

2. Ukulungiswa kwe-Formic Acid:

• I-asidi ye-formic idla ngokuveliswa ngokungxengwa kwe-methanol, kusetyenziswa i-catalyst efana ne-silver catalyst okanye i-rhodium catalyst.
• I-Methanol isabela kwi-oxygen xa kukho i-catalyst ukuze ivelise i-formic acid kunye namanzi.
• Impendulo ingenziwa kwisitya se-reactor phantsi kobushushu obulawulwayo kunye neemeko zoxinzelelo.

3. Impendulo yeCalcium Hydroxide kunye neFormic Acid:

• Kwisitya se-reactor, isisombululo se-calcium hydroxide sixutywa nesisombululo se-formic acid kwi-stoichiometric ratio ukuvelisa i-calcium formate.
• I-reaction idla ngokuba yi-exothermic, kwaye ubushushu bunokulawulwa ukuze kuphuculwe izinga lokuphendula kunye nemveliso.
• I-calcium formate iphuma njenge-solid, kwaye umxube we-reaction ungahluzwa ukuze kwahlulwe i-solid calcium formate kwi-liquid phase.

4. Ukwenziwa kwekristale kunye nokomisa:

• I-calcium formate eqinileyo efunyenwe kwi-reaction ingadlula kumanyathelo okucubungula angaphezulu afana ne-crystallization kunye nokomisa ukuze kufunyanwe imveliso oyifunayo.
• Ukwenziwa kwekristale kungenziwa ngokupholisa umxube wempendulo okanye ngokongeza isinyibilikisi ukukhuthaza ukwakheka kwekristale.
• Iikristale ze-calcium formate emva koko zahlulwa kwi-mother liquor kwaye zomiswe ukuze kususwe umswakama oseleyo.

5. Ukucoca kunye nokuPakisha:

• I-calcium formate eyomileyo ingathathwa amanyathelo okuhlanjululwa ukuze kususwe ukungcola nokuqinisekisa umgangatho wemveliso.
• I-calcium formate ecociweyo emva koko ipakishwa kwizikhongozeli okanye kwiingxowa ezifanelekileyo zokugcina, ukuthutha, kunye nokusasazwa kubasebenzisi bokugqibela.
• Amanyathelo okulawula umgangatho asetyenziswa kuyo yonke inkqubo yemveliso ukuqinisekisa ukuba imveliso yokugqibela iyahlangabezana neemfuno kunye neemfuno zomthetho.

Isiphelo:

Ukuveliswa kwe-calcium formate kubandakanya impendulo phakathi kwe-calcium hydroxide kunye ne-formic acid ukuvelisa i-compound efunekayo. Le nkqubo ifuna ulawulo olucokisekileyo lweemeko zokusabela, i-stoichiometry, kunye namanyathelo okucoca ukuze kufezekiswe ubunyulu kunye nemveliso ephezulu. I-calcium formate isetyenziswa kwizicelo ezahlukeneyo, kubandakanya njenge-additive concrete, i-additive feed, kunye nemveliso yesikhumba kunye nelaphu.
