Isopropanolkunye ne-ethanol zombini ii-alcohols, kodwa kukho ukungafani okuphawulekayo kwiipropati zabo ezenza ukuba zilungele izicelo ezahlukeneyo. Kweli nqaku, siza kuhlolisisa izizathu zokuba i-isopropanol isetyenziswe endaweni ye-ethanol kwiimeko ezahlukeneyo.

I-Isopropanol, ekwabizwa ngokuba yi-2-propanol, ilulwelo olungenambala, olubonakalayo olunevumba elimnandi. Iyaxubana namanzi kunye nezinyibilikisi ezininzi eziphilayo. I-Isopropanol isetyenziswa ngokuqhelekileyo njenge-solvent kwiindlela ezahlukeneyo zeekhemikhali kunye ne-arhente yokucoca iinjini kunye nezinye izixhobo zoshishino.

Kwelinye icala, i-ethanol nayo isiselo esinxilisayo kodwa inesakhiwo esahlukileyo. Ngokuqhelekileyo isetyenziswa njenge-solvent kunye ne-disinfectant, kodwa iipropati zayo zenza ukuba ingalungeli ezinye izicelo.

Makhe sijonge ezinye zezizathu zokuba i-isopropanol ikhethwa kwi-ethanol:

1. Amandla okunyibilikisa: I-Isopropanol inamandla okunyibilikisa anamandla xa kuthelekiswa ne-ethanol. Inokunyibilikisa uluhlu olubanzi lwezinto, iyenze ilungele ukusetyenziswa kwiinguqu ezahlukeneyo zemichiza apho ukunyibilika kubalulekile. Amandla okunyibilikisa e-Ethanol abuthathaka ngokwentelekiso, anciphisa ukusetyenziswa kwawo kwezinye iintshukumo zemichiza.

2. Iqondo lokubilisa: I-Isopropanol inomlinganiselo ophezulu wokubilisa kune-ethanol, oku kuthetha ukuba ingasetyenziselwa kumaqondo aphezulu ngaphandle kokunyuka lula. Oku kuyenza ilungele ukusetyenziswa kwemizi-mveliso apho kufuneka ukumelana nobushushu, njengokucocwa kweenjini kunye nabanye oomatshini.

3. I-solvent miscibility: I-Isopropanol ine-miscibility engcono ngamanzi kunye ne-solvents eninzi yezinto eziphilayo xa kuthelekiswa ne-ethanol. Oku kwenza kube lula ukusebenzisa kwimixube eyahlukeneyo kunye nokuqulunqwa ngaphandle kokubangela ukwahlukana kwesigaba okanye imvula. I-Ethanol, kwelinye icala, inomkhwa wokwahlula kumanzi kwindawo ephezulu, iyenza ingalungeli eminye imixube.

4. I-Biodegradability: Zombini i-isopropanol kunye ne-ethanol i-biodegradable, kodwa i-isopropanol inomlinganiselo ophezulu we-biodegradability. Oku kuthetha ukuba idiliza ngokukhawuleza kwimekobume, ukunciphisa nayiphi na impembelelo enokubakho kwimeko engqongileyo xa kuthelekiswa ne-ethanol.

5. Iingqwalasela zokhuseleko: I-Isopropanol inomda wokutsha ophantsi xa kuthelekiswa ne-ethanol, okwenza kube lula ukuphatha nokuthutha. Kwakhona inetyhefu ephantsi, inciphisa umngcipheko wokuvezwa kubaqhubi kunye nokusingqongileyo. I-Ethanol, nangona inetyhefu encinci kunezinye izinyibilikisi, inomlinganiselo ophezulu wokutsha kwaye kufuneka iphathwe ngononophelo.

Ekugqibeleni, ukhetho phakathi kwe-isopropanol kunye ne-ethanol luxhomekeke kwisicelo esithile kunye neemfuno. Amandla okunyibilikisa anamandla e-Isopropanol, indawo yokubilisa ephezulu, ukungahambi kakuhle kwamanzi kunye nezinyibilikisi ze-organic, izinga eliphezulu lokubola kwe-biodegradability, kunye neempawu zokuphatha ezikhuselekileyo zenza ukuba utywala obuguquguqukayo kunye nokukhethwa kotywala kumashishini amaninzi kunye nezorhwebo xa kuthelekiswa ne-ethanol.
