Isopropanolkanye ne-ethanol kokubili kuwutshwala, kodwa kunomehluko ophawulekayo ezindaweni zabo ezibenza bafanelekele ukusetshenziswa okuhlukile. Kulesi sihloko, sizohlola izizathu zokuthi kungani i-isopropanol isetshenziswa esikhundleni se-ethanol ezimweni ezihlukahlukene.
I-Isopropanol, eyaziwa nangokuthi i-2-propanol, iwuketshezi olungenambala, olune-viscous olunephunga elimnandi kancane. Ixubene namanzi nezinyibilikisi eziningi eziphilayo. I-Isopropanol ivame ukusetshenziswa njenge-solvent ekuphenduleni kwamakhemikhali okuhlukahlukene futhi njenge-ejenti yokuhlanza izinjini nezinye izinto zokusebenza zezimboni.
Ngakolunye uhlangothi, i-ethanol nayo ingutshwala kodwa inesakhiwo esihlukile. Ivamise ukusetshenziswa njenge-solvent kanye nesibulala-magciwane, kodwa izakhiwo zayo zenza ingafaneleki kwezinye izinhlelo zokusebenza.
Ake sibheke ezinye zezizathu zokuthi kungani isopropanol ikhethwa kune-ethanol:
1. Amandla e-solvent: I-Isopropanol inamandla okuncibilikisa anamandla uma kuqhathaniswa ne-ethanol. Ingancibilikisa inhlobonhlobo yezinto, iyenze ifanelekele ukusetshenziswa ekuphenduleni kwamakhemikhali okuhlukahlukene lapho ukuncibilika kubalulekile. Amandla okuncibilikisa e-Ethanol abuthakathaka uma kuqhathaniswa, anciphisa ukusetshenziswa kwawo kwezinye izimo zamakhemikhali.
2. Iphuzu lokubilisa: I-Isopropanol inephuzu lokubilisa eliphakeme kune-ethanol, okusho ukuthi ingasetshenziswa emazingeni okushisa aphezulu ngaphandle kokuhwamuka kalula. Lokhu kuyenza ifanelekele izinhlelo zokusebenza zezimboni lapho kudingeka ukumelana nokushisa, njengalapho kuhlanzwa izinjini neminye imishini.
3. I-solvent miscibility: I-Isopropanol inokuxubeka okungcono namanzi kanye nezincibilikisi eziningi eziphilayo uma kuqhathaniswa ne-ethanol. Lokhu kwenza kube lula ukusetshenziswa emixubeni ehlukahlukene kanye nokwakheka ngaphandle kokubangela ukuhlukana kwesigaba noma imvula. I-Ethanol, ngakolunye uhlangothi, inomkhuba wokuhlukana namanzi ekugxilweni okuphezulu, okwenza ingalungeli ezinye izingxube.
4. I-Biodegradability: Kokubili isopropanol ne-ethanol kungabola, kodwa i-isopropanol inezinga eliphezulu lokubola kwe-biodegradability. Lokhu kusho ukuthi iphuka ngokushesha emvelweni, inciphisa noma yimuphi umthelela ongaba khona endaweni ezungezile uma kuqhathaniswa ne-ethanol.
5. Ukucatshangelwa kokuphepha: I-Isopropanol inomkhawulo ophansi wokuvutha uma kuqhathaniswa ne-ethanol, okwenza kube okuphephile ukuphatha nokuthutha. Futhi inobuthi obuphansi, inciphisa ubungozi bokuchayeka ku-opharetha kanye nemvelo. I-Ethanol, nakuba ingenabuthi obuncane kunezinye izincibilikisi, inomkhawulo ophezulu wokuvutha futhi kufanele isingathwe ngokuqapha.
Sengiphetha, ukukhetha phakathi kwe-isopropanol ne-ethanol kuncike ekusetshenzisweni okukhethekile kanye nezidingo. Amandla okuncibilikisa anamandla e-Isopropanol, indawo yokubilisa ephakeme, ukungezwani okungcono kwamanzi nezincibilikisi eziphilayo, izinga eliphezulu lokubola kwe-biodegradability, kanye nezakhiwo zokuphatha eziphephile zikwenza kube utshwala obuguquguqukayo nobukhethwayo ezisetshenziswa eziningi zezimboni nezohwebo uma kuqhathaniswa ne-ethanol.
