Isopropanoliwuketshezi olungenambala, oluvutha umlilo olusetshenziswa kakhulu ezimbonini ezihlukahlukene ezifana nezincibilikisi, amarabha, izinto zokunamathisela, nezinye. Enye yezindlela eziyinhloko zokukhiqiza isopropanol ngokusebenzisa i-hydrogenation ye-acetone. Kulesi sihloko, sizongena sijule kule nqubo.

Isinyathelo sokuqala ekuguquleni i-acetone ibe isopropanol ngokusebenzisa i-hydrogenation. Lokhu kufezwa ngokuphendula i-acetone negesi ye-hydrogen phambi kwe-catalyst. I-equation yokusabela kule nqubo ithi:

2CH3C(O)CH3 + 3H2 -> 2CH3CHOHCH3

I-catalyst esetshenziswe kulokhu kusabela ngokuvamile iyinsimbi ehloniphekile njenge-palladium noma i-platinum. Inzuzo yokusebenzisa i-catalyst ukuthi yehlisa amandla okwenza kusebenze adingekayo ukuze ukusabela kuqhubeke, kwandise ukusebenza kahle kwayo.

Ngemuva kwesinyathelo se-hydrogenation, umkhiqizo owumphumela uyingxube ye-isopropanol namanzi. Isinyathelo esilandelayo kule nqubo sihlanganisa ukuhlukanisa izingxenye ezimbili. Lokhu kuvame ukwenziwa kusetshenziswa izindlela ze-distillation. Amaphuzu abilayo wamanzi kanye ne-isopropanol asondelene kakhulu, kodwa ngochungechunge lwe-distillations eyingxenye, angahlukaniswa ngokuphumelelayo.

Uma amanzi esusiwe, umkhiqizo owumphumela uyi-isopropanol ehlanzekile. Kodwa-ke, ngaphambi kokuthi isetshenziswe ezinhlelweni ezihlukahlukene, kungase kudingeke ukuthi kudlule ezinye izinyathelo zokuhlanzwa njengokuphelelwa amanzi emzimbeni noma i-hydrogenation ukuze kukhishwe noma yikuphi ukungcola okusalele.

Inqubo yonke yokukhiqiza isopropanol kusuka ku-acetone ihilela izinyathelo ezintathu eziyinhloko: i-hydrogenation, ukuhlukaniswa, nokuhlanzwa. Isinyathelo ngasinye sidlala indima ebalulekile ekuqinisekiseni ukuthi umkhiqizo wokugcina uhlangabezana nokuhlanzeka kanye nekhwalithi oyifunayo.

Manje njengoba usuqonda kangcono ukuthi i-isopropanol ikhiqizwa kanjani kusuka ku-acetone, ungakwazi ukuqonda isimo esiyinkimbinkimbi sale nqubo yokuguqulwa kwamakhemikhali. Inqubo idinga inhlanganisela yakho kokubili ukusabela komzimba namakhemikhali ukuze kwenzeke ngendlela elawulwayo ukuze kukhiqizwe i-isopropanol yekhwalithi ephezulu. Ukwengeza, ukusetshenziswa kwama-catalysts, njenge-palladium noma iplatinamu, kudlala indima ebalulekile ekuthuthukiseni ukusebenza kahle kokusabela.
