I-Isobutanol, eyaziwa nangokuthi i-Isopropyl Alcohol, i-2-methyl propanol iyi-opobiwo yotshwala engenamibala. I-Isobutanol ingenye yezithako eziphambili zamaqabunga etiye amasha, itiye elimnyama netiye eliluhlaza ukukhiqiza iphunga elimangalisayo ngesisindo samangqamuzana esingu-74.66 ℃, i-20/4 ℃), i-16/4 ℃), inkomba eyevusayo nephuzu le-flash lika-37 ℃. I-Isobutanol ichithe ngokuphelele utshwala ne-ether, incibilika kancane emanzini. Umphunga wayo angakha ingxube eqhumayo emoyeni; Umkhawulo wokuqhuma ngu-2.4% (ivolumu). Ingakha amakhompiyutha okungeziwe (i-CACL2 • 3c4h10o) nge-calcium chloride. I-Isobutanol ingatholwa yi-distillation yomkhiqizo we-methanol futhi nayo ingasuselwa ekuhlolweni kwamafutha e-crude fusel. Kusetshenziswa i-carbonyl ye-carbonyl yezimboni njenge-catalyst, ukwenza i-propelene kanye ne-carbon monoxide ne-hydrogen ingxube ye-107 ~ 140 ° C, bese kuba yi-asobutyticdehyde, bese nge-catalytic hydrogenation, ukuhlukaniswa kwe-aspogenanol, ukwahlukana kungathola i-isobananol. I-Isobutanol isetshenziswa ekwenziweni kwezithasiselo zikaphethiloli, ama-antioxidants, amapulasitiki, irabha yokwenziwa, ama-musk okufakelwa kanye nezidakamizwa zokwenziwa futhi asetshenziswe njengezixazululo zamakhemikhali kanye namakhemikhali wamakhemikhali.
