Methanol kanyesowopropanolziyizixazululo ezimbili ezivame ukusetshenziswa kwezimboni. Ngenkathi bahlanganyela ngokufana okuthile, nabo banezakhiwo ezihlukile nezimpawu ezibekele zona. Kulesi sihloko, sizokwelulwa ekucacisweni kwalezi zinhlava ezimbili, siqhathanisa izakhiwo zazo ezingokomzimba nezamakhemikhali, kanye nezicelo zabo kanye namaphrofayili okuphepha.

Ake siqale nge-methanol, eyaziwa nangokuthi ngotshwala bezinkuni. Kuwuketshezi olucacile, olungenamibala olungenakuphikwa ngamanzi. I-Methanol inendawo evuthayo ephansi yama-degrees angama-65, awenza alungele ukusetshenziswa ezinhlelweni zokushisa okuphansi. Inesilinganiso esiphakeme se-octane, okusho ukuthi ingasetshenziswa njenge-solvent kanye ne-ejenti ye-anti-knock ngophethiloli.

I-Methanol isetshenziswa futhi njenge-feedstock ekukhiqizweni kwamanye amakhemikhali, njenge-formaldehyde ne-dimethyl ether. Iphinde yaqashwa ekukhiqizweni kwe-biodiesel, umthombo wamaphethiloli ovuselelekayo. Ngaphezu kwezinhlelo zayo zezimboni, i-methanol nayo isetshenziswa ekukhiqizweni kwama-varnish nama-lacquers.

Manje ake sibhekele i-isopropanol, eyaziwa nangokuthi 2-propapol noma i-dimethyl ether. Le solvent nayo icacile futhi ingenamibala, ngephuzu elibilayo liphakeme kancane kune-methanol kuma-degree angama-82 Celsius. I-Sopropanol iyingozi kakhulu ngamanzi nama-lipids, okwenza kube yi-solvent enhle kakhulu yezinhlelo eziningi. Isetshenziswa kakhulu njenge-ejenti yokusika epende ncamashi nasekukhiqizweni kwamagilavu ​​we-latex. I-Sopropanol nayo isetshenziswa ekukhiqizweni kwezikhangiso, ama-sealants, namanye ama-polymers.

Uma kukhulunywa ngokuphepha, zombili i-methanol ne-isopropanol zinezingozi zazo ezihlukile. I-Methanol inobuthi futhi ingadala ubumpumputhe uma buhlelwe emehlweni noma bangena. Kubuye kuvuswe kakhulu futhi kuqhume lapho kuxutshwa nomoya. Ngakolunye uhlangothi, i-sopropanol inokulinganiselwa okuvuthayo okuvuthayo futhi kuqhuma kancane kune-methanol lapho kuxutshwe nomoya. Kodwa-ke, kusavunyelwa futhi kufanele kusingathwe ngokunakekelwa.

Ekuphetheni, i-methanol ne-isopropanol zombili ziyizinto ezibalulekile zezimboni ngezakhiwo zazo ezihlukile kanye nezicelo. Ukukhetha phakathi kwabo kuya ngezidingo ezithile zohlelo lokusebenza nephrofayili yezokuphepha ye-solvent ngayinye. I-Methanol inendawo ebilayo ephansi futhi iqhuma kakhudlwana, kanti isopropanol inendawo ephakeme ebilayo futhi ayiqhumiswanga kangako kepha isenzakale. Lapho ukhetha i-solvent, kubalulekile ukucubungula izakhiwo zayo ezibonakalayo, ukuqina kwamakhemikhali, ubuthi kanye nephrofayili yokuvutha ukuze kuqinisekiswe ukusetshenziswa okuphephile nokusebenzayo.
