Isopropanolthiab ethanol yog ob qho tib si cawv, tab sis muaj qhov sib txawv tseem ceeb hauv lawv cov khoom uas ua rau lawv haum rau kev siv sib txawv.Hauv tsab xov xwm no, peb yuav tshawb txog cov laj thawj vim li cas isopropanol siv los hloov ethanol hauv ntau qhov xwm txheej.

Isopropanol, tseem hu ua 2-propanol, yog ib qho tsis muaj xim, kua nplaum nrog lub qab zib me ntsis.Nws yog miscible nrog dej thiab feem ntau cov kuab tshuaj organic.Isopropanol feem ntau yog siv los ua cov kuab tshuaj nyob rau hauv ntau yam tshuaj tiv thaiv thiab ua tus neeg saib xyuas rau lub cav thiab lwm yam khoom siv.

Ntawm qhov tod tes, ethanol kuj yog cawv tab sis nrog cov qauv sib txawv.Nws yog feem ntau siv los ua cov kuab tshuaj thiab tshuaj tua kab mob, tab sis nws cov khoom ua rau nws tsis haum rau qee qhov kev siv.

Cia peb saib qee qhov laj thawj vim li cas isopropanol nyiam rau ethanol:

1. Lub zog hnyav: Isopropanol muaj zog hnyav zog piv rau ethanol.Nws tuaj yeem yaj ntau yam ntawm cov tshuaj, ua rau nws tsim nyog rau kev siv ntau yam tshuaj lom neeg uas yog qhov tseem ceeb ntawm solubility.Ethanol lub zog hnyav yog qhov tsis muaj zog, txwv tsis pub siv qee yam tshuaj lom neeg.

2. Boiling point: Isopropanol muaj qhov kub siab dua li ethanol, uas txhais tau tias nws tuaj yeem siv rau qhov kub siab dua yam tsis muaj evaporating yooj yim.Qhov no ua rau nws tsim nyog rau cov ntawv thov kev lag luam uas yuav tsum tau ua kom sov, xws li hauv kev tu lub cav thiab lwm yam tshuab.

3. Cov kuab tshuaj miscibility: Isopropanol muaj miscibility zoo dua nrog dej thiab feem ntau cov kuab tshuaj organic piv rau ethanol.Qhov no ua rau nws yooj yim dua rau kev siv ntau yam sib tov thiab cov formulations tsis ua rau theem sib cais lossis nag lossis daus.Ethanol, ntawm qhov tod tes, muaj kev nyiam sib cais los ntawm cov dej ntawm qhov siab, ua rau nws tsis haum rau qee qhov sib xyaw.

4. Biodegradability: Ob leeg isopropanol thiab ethanol yog biodegradable, tab sis isopropanol muaj ntau dua biodegradability tus nqi.Qhov no txhais tau tias nws tawg sai dua nyob rau hauv ib puag ncig, txo cov kev cuam tshuam ntawm ib puag ncig piv rau ethanol.

5. Kev txiav txim siab txog kev nyab xeeb: Isopropanol muaj qhov cuam tshuam qis dua piv rau ethanol, ua rau nws muaj kev nyab xeeb dua los tuav thiab thauj.Nws kuj muaj cov tshuaj toxicity qis, txo qhov kev pheej hmoo ntawm kev raug rau cov neeg ua haujlwm thiab ib puag ncig.Ethanol, txawm hais tias tsis muaj tshuaj lom ntau dua li lwm cov kuab tshuaj, muaj kev txwv ntau dua thiab yuav tsum tau ceev faj.

Hauv kev xaus, kev xaiv ntawm isopropanol thiab ethanol nyob ntawm cov ntawv thov tshwj xeeb thiab cov cai.Isopropanol lub zog hnyav dua, qhov kub siab dua, zoo dua miscibility nrog dej thiab cov kuab tshuaj organic, ntau dua biodegradability tus nqi, thiab kev tuav ruaj ntseg ua rau nws muaj ntau yam thiab nyiam cawv rau ntau daim ntawv thov kev lag luam thiab kev lag luam piv rau ethanol.
