Isopropanolkanye ne-ethanol kokubili kuwutshwala, kodwa kunomehluko omkhulu ezimpahleni 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. Ukuxubana kwe-solvent: 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 e-Isopropanol anamandla, 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.
