Okokuqala, ukuvutshelwa kuwuhlobo lwenqubo yezinto eziphilayo, okuyinqubo eyinkimbinkimbi yezinto eziphilayo yokuguqula ushukela ube yi-carbon dioxide notshwala ngaphansi kwezimo ze-anaerobic. Kule nqubo, ushukela ubola nge-anaerobically ube yi-ethanol ne-carbon dioxide, bese i-ethanol ibuye iboliswe ibe i-acetic acid ne-carbon dioxide.

Isopropanolwuhlobo lotshwala, oluwuketshezi oluguquguqukayo noluvutha kalula. Ngokuvamile isetshenziswa njenge-solvent kanye ne-antifreeze. Enqubweni yokuvutshelwa, ushukela ubola nge-anaerobically ube yi-ethanol ne-carbon dioxide, ukuze kukhiqizwe isopropanol. Ngakho-ke, kungashiwo ukuthi isopropanol iwumkhiqizo wokuvutshelwa.

Kodwa-ke, inqubo yokuvutshelwa iyinkimbinkimbi kakhulu, futhi izimo nezinto ezidingekayo zokuvutshelwa zihlukile. Ngaphezu kwalokho, imikhiqizo yokuvutshelwa ingase ihluke. Ngakho-ke, izimo ezithile nezinto ezidingekayo ekukhiqizeni isopropanol azicacile.

Ngokuvamile, i-isopropanol iwumkhiqizo wokuvutshelwa. Nokho, izimo ezithile nezinto ezidingekayo ekukhiqizeni kwayo akucaci. Kudingeka ukuqhubeka nokutadisha inqubo yokuvutshelwa kanye nezimo nezinto ezidingekayo ekukhiqizeni kwayo ukuze uthole ulwazi olunembile mayelana nokukhiqizwa kwe-isopropanol.
