Methanol kanyeisopropanolyizincibilikisi ezimbili ezivame ukusetshenziswa ezimbonini.Nakuba babelana ngokufana okuthile, banezinto ezihlukile nezici ezibenza bahluke.Kulesi sihloko, sizocubungula imininingwane yalezi zinyibiliki ezimbili, siqhathanise izakhiwo zazo ezingokomzimba namakhemikhali, kanye nezicelo zazo kanye namaphrofayili okuphepha.

Ake siqale nge-methanol, eyaziwa nangokuthi utshwala bezinkuni.Iwuketshezi olucacile, olungenambala oluxubene namanzi.I-Methanol inezinga eliphansi lokubilisa elingu-65 degrees Celsius, okuyenza ifanelekele ukusetshenziswa ezindaweni ezisezingeni eliphansi lokushisa.Inezinga eliphezulu le-octane, okusho ukuthi lingasetshenziswa njengesixazululi kanye ne-anti-knock ejenti kuphethiloli.

I-Methanol iphinde isetshenziswe njenge-feedstock ekukhiqizeni amanye amakhemikhali, njenge-formaldehyde ne-dimethyl ether.Iphinde isetshenziswe ekukhiqizeni i-biodiesel, umthombo wamafutha ovuselelekayo.Ngaphezu kwezicelo zayo zezimboni, i-methanol iphinde isetshenziswe ekukhiqizeni ama-varnishes nama-lacquers.

Manje ake sibhekise ukunaka kwethu ku-isopropanol, eyaziwa nangokuthi i-2-propanol noma i-dimethyl ether.Lesi sincibilikisi futhi sicacile futhi asinambala, sinephuzu lokubila elingaphezulu kancane kune-methanol ku-82 degrees Celsius.I-Isopropanol ixubene kakhulu nakho kokubili amanzi kanye nama-lipids, okuyenza ibe isinyibilikisi esihle kakhulu sezinhlelo zokusebenza eziningi.Ngokuvamile isetshenziswa njenge-ejenti yokusika kuma-paint thinners kanye nokukhiqizwa kwamagilavu ​​e-latex.I-Isopropanol iphinde isetshenziswe ekukhiqizeni okunamathelayo, ama-sealants, namanye ama-polymers.

Uma kuziwa ekuphepheni, kokubili i-methanol ne-isopropanol zinezingozi zazo eziyingqayizivele.I-Methanol inobuthi futhi ingabangela ubumpumputhe uma ichaphazwe emehlweni noma idliwe.Iphinde ivuthe kakhulu futhi iqhume uma ixutshwe nomoya.Ngakolunye uhlangothi, i-isopropanol inezinga eliphansi lokuvutha futhi ayiqhume kakhulu kune-methanol uma ixutshwe nomoya.Nokho, isavutha futhi kufanele iphathwe ngokucophelela.

Sengiphetha, i-methanol ne-isopropanol zombili izincibilikisi ezibalulekile zezimboni ezinezakhiwo zazo ezihlukile kanye nezicelo.Ukukhetha phakathi kwabo kuncike ezidingweni ezithile zohlelo lokusebenza kanye nephrofayili yokuphepha ye-solvent ngayinye.I-Methanol inephuzu eliphansi lokubilisa futhi iqhuma kakhulu, kuyilapho i-isopropanol inephuzu lokubila eliphezulu futhi ayiqhume kangako kodwa isavutha.Uma ukhetha i-solvent, kubalulekile ukucabangela izici zayo ezibonakalayo, ukuzinza kwamakhemikhali, ubuthi, kanye nephrofayili yokuvutha ukuze kuqinisekiswe ukusetshenziswa okuphephile nokuphumelelayo.
