I-acetone iyi-solvent esetshenziswa kakhulu ephilayo enezinhlobonhlobo zezimboni, okuhlanganisa upende, izinto zokunamathisela, nezinto zikagesi. I-Isopropyl alcohol nayo iyisinyibilikisi esivamile esisetshenziswa ezinhlobonhlobo zezinqubo zokukhiqiza. Kulesi sihloko, sizohlola ukuthi i-acetone ingenziwa yini nge-isopropyl alcohol.
Indlela eyinhloko yokuguqula utshwala be-isopropyl bube i-acetone ngenqubo ebizwa ngokuthi i-oxidation. Le nqubo ihilela ukusabela kotshwala nge-oxidizing agent, efana ne-oxygen noma i-peroxide, ukuze buguqulelwe ku-ketone yayo ehambisanayo. Endabeni ye-isopropyl alcohol, i-ketone ewumphumela yi-acetone.
Ukwenza lokhu kusabela, i-isopropyl alcohol ixutshwa negesi ye-inert njenge-nitrogen noma i-argon phambi kwe-catalyst. I-catalyst esetshenziswe kulokhu kusabela ngokuvamile i-oxide yensimbi, njenge-manganese dioxide noma i-cobalt(II) oxide. Ukusabela bese kuvunyelwa ukuqhubeka emazingeni okushisa aphezulu kanye nezingcindezi.
Enye yezinzuzo eziyinhloko zokusebenzisa utshwala be-isopropyl njengento yokuqala yokwenza i-acetone ukuthi ishibhile uma kuqhathaniswa nezinye izindlela zokukhiqiza i-acetone. Ukwengeza, le nqubo ayidingi ukusetshenziswa kwama-reagents asebenzayo kakhulu noma amakhemikhali ayingozi, okuyenza iphephe futhi ihambisane nemvelo.
Nokho, zikhona nezinye izinselelo ezihlobene nale ndlela. Enye yezingqinamba eziyinhloko ukuthi le nqubo idinga amazinga okushisa aphezulu kanye nezingcindezi, okwenza ibe namandla kakhulu. Ukwengeza, i-catalyst esetshenziswe ekuphenduleni kungase kudingeke ukuthi ishintshwe ngezikhathi ezithile noma yenziwe kabusha, okungase kwenyuse izindleko eziphelele zenqubo.
Ekuphetheni, kungenzeka ukukhiqiza i-acetone kusuka ku-isopropyl alcohol ngokusebenzisa inqubo ebizwa ngokuthi i-oxidation. Nakuba le ndlela inezinzuzo ezithile, njengokusebenzisa into yokuqala engabizi kakhulu futhi engadingi ama-reagents asebenza kakhulu noma amakhemikhali ayingozi, futhi inezihibe ezithile. Izinselelo ezinkulu zihlanganisa izidingo eziphezulu zamandla kanye nesidingo sokushintshwa ngezikhathi ezithile noma ukuvuselelwa kwe-catalyst. Ngakho-ke, lapho ucabangela ukukhiqizwa kwe-acetone, kubalulekile ukucabangela izindleko zizonke, umthelela wendawo, kanye nokwenzeka kobuchwepheshe bendlela ngayinye ngaphambi kokwenza isinqumo ngomzila wokukhiqiza ofaneleka kakhulu.
