Isobutanol, ekwabizwa ngokuba yi-Iyopropyl Utywala, i-2-methyl propanol ngulwelo olungenamibala kotywala. Isobutanol yenye yezona zithako ziphambili zamagqabi amagqabi amatsha, iti emnyama kunye neti eluhlaza ukuze avelise ivumba elimnandi le-78.66, inqaku lokubila le-78.66 ℃, i-10/4 kunye nenqaku leflethi ezingama-37 ℃. Isobutanol ichithwe ngokupheleleyo kutywala kwaye i-ether, inyibilikiswe kancinci emanzini. Umphunga wayo unokwenza umxube wokuqhushumba unomoya; Umda wokuqhuma yi-2.4% (ivolumu). Ingayenza imijikelezo yongezwa (i-Cacl2 • 3c4h10o) nge-calcium chloride. I-isobutanol inokufunyanwa ngokukhululeka kwemveliso ye-methanol kwaye inakho ukwathathwe kwidilifayi ye-oyile e-crade fusel. Ukusebenzisa i-carbonyl ye-carbonyl ye-Coutalyst, yenza i-proplon kunye nomxube we-probon kunye ne-hydrogen ye-hydrogen iphendule i-bhyraldehyde kunye ne-shydrogening ye-hydrogening, kwaye emva koko kwahlukaniswa kwe-isobutanol. I-isobutanol isetyenziswa ekwenziweni kwe-petroleum yongezwa, i-antioxididants, iiplasitiki, irabha ye-synticletic, i-oyile ye-oyile kunye ne-oyile ye-oyile kwaye ikwasetyenziswa njengamachiza kunye nokuhlaziywa kweekhemikhali.
