Isopropanoliyincibilikisi yasezimbonini esetshenziswa kakhulu, futhi izinto zayo ezingavuthiwe zitholakala ikakhulu kumafutha ezinto ezimbiwa phansi. Izinto ezisetshenziswa kakhulu zokusetshenziswa yi-n-butane ne-ethylene, etholakala kuwoyela ongahluziwe. Ngaphezu kwalokho, i-isopropanol ingabuye ihlanganiswe kusuka ku-propylene, umkhiqizo ophakathi we-ethylene.

I-solvent ye-Isopropanol

 

Inqubo yokukhiqiza ye-isopropanol iyinkimbinkimbi, futhi izinto zokusetshenziswa zidinga ukubhekana nochungechunge lokusabela kwamakhemikhali kanye nezinyathelo zokuhlanza ukuze kutholwe umkhiqizo oyifunayo. Ngokuvamile, inqubo yokukhiqiza ihlanganisa i-dehydrogenation, i-oxidation, i-hydrogenation, ukuhlukaniswa nokuhlanzwa, njll.

 

Okokuqala, i-n-butane noma i-ethylene i-dehydrogenated ukuthola i-propylene. Ngemuva kwalokho, i-propylene i-oxidized ukuthola i-acetone. I-acetone ibe i-hydrogenated ukuze ithole isopropanol. Okokugcina, i-isopropanol idinga ukuhlukaniswa nezinyathelo zokuhlanza ukuze ithole umkhiqizo wokuhlanzeka okuphezulu.

 

Ngaphezu kwalokho, i-isopropanol ingabuye ihlanganiswe kwezinye izinto zokusetshenziswa, njengoshukela kanye ne-biomass. Nokho, lezi zinto zokusetshenziswa azisetshenziswa kakhulu ngenxa yesivuno sazo esiphansi kanye nezindleko eziphakeme.

 

Izinto ezisetshenziswayo zokukhiqizwa kwe-isopropanol ngokuyinhloko zitholakala kumafutha ezinto ezimbiwa phansi, ezingadli kuphela izinsiza ezingavuseleleki kodwa futhi zibangele izinkinga zemvelo. Ngakho-ke, kuyadingeka ukuthuthukisa izinto ezintsha zokusetshenziswa kanye nezinqubo zokukhiqiza ukuze kuncishiswe ukusetshenziswa kwezibaseli ezimbiwa phansi kanye nokungcoliswa kwemvelo. Njengamanje, abanye abacwaningi sebeqalile ukuhlola ukusetshenziswa kwezinsiza ezivuselelekayo (i-biomass) njengezinto zokusetshenziswa zokukhiqiza i-isopropanol, ezingase zinikeze izindlela ezintsha zokuthuthukiswa okusimeme kwemboni ye-isopropanol.
