Ndi Kupaka Mowa, Isopropyl Mowa Wofanana ndi Hydrogen Peroxide
Isopropanol, ethanol (yomwe nthawi zambiri imatchedwa kusisita mowa), ndi hydrogen peroxide ndi zinthu zitatu zosiyana za mankhwala. Ngakhale ali ndi ntchito zofanana pakupha tizilombo toyambitsa matenda ndi kuyeretsa, katundu wawo wamankhwala, ntchito, ndi njira zomwe amachitira zimasiyana akaganiziridwa ndi momwe amapangira gasi wamakampani.
Isopropanol (Mowa wa Isopropyl)
Chemical formula: C₃H₈O
Njira Yopangira Gasi: Kuyaka
Isopropanol, ikawotchedwa, imapanga carbon dioxide ndi madzi, kutulutsa kutentha ndi mpweya. Zomwe zimachitika ndi izi:
2C3H8O+9O2→6CO2+8H2O2C3H8O+9O2 → 6CO2+8H2O
Izi zimapanga mpweya woipa (CO₂), womwe ukhoza kukhala wothandiza m'malo otentha kwambiri, okhala ndi mphamvu zamagetsi. Isopropanol imatha kukhala ngati mafuta kapena gwero la gasi muzochitika zotere.
Kuwola kwa Thermal: Pa kutentha kwambiri, isopropanol ikhoza kuchitidwa pyrolysis, kutulutsa mamolekyu ang'onoang'ono monga propylene ndi methane.
Kugwiritsa ntchito Isopropanol: M'mafakitale omwe amafunikira mpweya (monga carbon dioxide) ndi kutentha, isopropanol ikhoza kukhala ngati mafuta a mankhwala. Komabe, nthawi zambiri amagwiritsidwa ntchito popanga mpweya wabwino ndipo amagwiritsidwa ntchito makamaka popanga mpweya woipa wopangidwa pakayaka.
Ethanol (Mowa Wopaka)
Chemical formula: C₂H₅OH
Njira Yopangira Gasi: Kuyaka, Kusintha kwa Nthunzi, Kutentha
Ethanol amawotcha kuti apange mpweya woipa ndi madzi. Zomwe zimachitika ndi izi:
C2H5OH+3O2→2CO2+3H2OC2H5OH+3O2→ 2CO2+3H2O
The mpweya woipa kwaiye pa kuyaka Mowa ndi ofanana ndi opangidwa ndi isopropanol, koma Mowa ambiri amatulutsa kutentha kwambiri, kupanga mafuta abwino mu nkhani zazikulu kuyaka gasi.
Kusintha kwa Steam: Ethanol imakhudzidwa ndi mpweya wamadzi pa kutentha kwambiri kuti ipange haidrojeni (H₂) ndi carbon monoxide (CO). Izi zimagwiritsidwa ntchito kwambiri popanga haidrojeni:
C2H5OH+H2O→CO+3H2C2H5OH+H2O→CO+3H2
Njirayi ndiyofunikira kwambiri pakupanga gasi wamakampani omwe amafunikira haidrojeni ngati zopangira.
Kuyanika: Pazifukwa zenizeni, Mowa amatha kupangidwa kudzera mu nayonso mphamvu, yomwe imatulutsanso mpweya monga mpweya woipa ndi methane, kutengera momwe kagayidwe kake kamayambitsa tizilombo toyambitsa matenda.
Kugwiritsa ntchito Ethanol: Mowa amagwiritsidwa ntchito kwambiri m'mafakitale popanga haidrojeni, carbon dioxide, ndi mpweya woyaka. Imathandiza kwambiri pakupanga mafuta, kaphatikizidwe ka gasi wamankhwala (monga haidrojeni ndi methane), ndi njira zina zamafakitale.
Hydrogen Peroxide
Chemical formula: H₂O₂
Njira Yopangira Gasi: Kuwola Reaction
Hydrogen peroxide ndi okosijeni kwambiri, ndipo ikawola, imatulutsa madzi ndi mpweya. Zomwe zimachitika ndi izi:
2H2O2→2H2O+O22H2O2→ 2H2O+O2
Kuwola kwa hydrogen peroxide kumatulutsa mpweya wa okosijeni, womwe ndi njira yayikulu yopangira mpweya.
Kuwola kwa Catalytic: Zomwe zimawola zimatha kufulumizitsidwa ndi zopangira (monga manganese dioxide kapena chitsulo), kutulutsa mpweya wabwino kwambiri. Mpweya uwu umagwiritsidwa ntchito m'mafakitale omwe amafunikira mpweya wambiri.
Kugwiritsa ntchito haidrojeni peroxide: Hydrogen peroxide imagwira ntchito yofunika kwambiri kupanga mpweya, makamaka m'makampani opanga mankhwala (mwachitsanzo, makutidwe ndi okosijeni, kupanga feteleza). Mpweya umene umapangidwa chifukwa cha kuwonongeka kwake ndi wofunika kwambiri mu kaphatikizidwe ka mankhwala ndi ntchito zina za mafakitale zomwe zimafuna mpweya wabwino kwambiri.

Kufotokozera patebulo:
Mowa wa Isopropyl: makamaka umapanga mpweya woipa wa carbon dioxide ndi nthunzi wa madzi kupyolera mu kuyaka, komanso ukhoza kupanga mpweya wochepa wa hydrocarbon monga ethylene ndi methane kupyolera mu pyrolysis.
Ethanol: imapanga mpweya woipa ndi mpweya wa madzi kupyolera mu kuyaka, haidrojeni ndi mpweya wa carbon monoxide kupyolera mu kusintha kwa nthunzi, ndipo amathanso kupanga mpweya woipa kudzera mu nayonso mphamvu.
Hydrogen peroxide: imawola kuti ipange mpweya, womwe nthawi zambiri umagwiritsidwa ntchito popanga mpweya m'ma laboratories kapena m'mafakitale.
