Isopropanollulwelo olungenambala, olunokutsha olusetyenziswa kakhulu kumashishini ahlukeneyo afana nezinyibilikisi, iirabha, izinto zokuncamathelisa, kunye nezinye. Enye yeendlela eziphambili zokuvelisa i-isopropanol ngokusebenzisa i-hydrogenation ye-acetone. Kweli nqaku, siza kungena nzulu kule nkqubo.

Isinyathelo sokuqala sokuguqulwa kwe-acetone kwi-isopropanol yi-hydrogenation. Oku kuphunyezwa ngokuphendula i-acetone ngegesi ye-hydrogen phambi kwe-catalyst. I-reaction equation yale nkqubo yile:

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

I-catalyst esetyenziswe kule ndlela yokusabela ngokuqhelekileyo yintsimbi ehloniphekileyo njengepalladium okanye iplatinam. Inzuzo yokusebenzisa i-catalyst kukuba yehlisa amandla okuvuselela afunekayo ukuze impendulo iqhubeke, inyusa ukusebenza kwayo.

Emva kwesinyathelo se-hydrogenation, imveliso ebangelwa ngumxube we-isopropanol kunye namanzi. Inyathelo elilandelayo kwinkqubo kubandakanya ukwahlula amacandelo amabini. Oku kuqhele ukwenziwa kusetyenziswa iindlela zokuhluza. Amanqaku abilayo amanzi kunye ne-isopropanol asondelene ngokusondeleyo, kodwa ngoluhlu lwe-distillations ye-fractional, anokwahlulwa ngokufanelekileyo.

Emva kokuba amanzi esusiwe, imveliso ebangelwa yi-isopropanol ecocekileyo. Nangona kunjalo, ngaphambi kokuba isetyenziswe kwizicelo ezahlukeneyo, kunokufuneka ukuba iqhubele phambili amanyathelo okucoca afana nokuphelelwa ngamanzi emzimbeni okanye i-hydrogenation ukususa nakuphi na ukungcola okushiyekileyo.

Inkqubo iyonke yokuvelisa i-isopropanol kwi-acetone ibandakanya amanyathelo amathathu aphambili: i-hydrogenation, ukwahlukana, kunye nokucoca. Inyathelo ngalinye lidlala indima ebalulekileyo ekuqinisekiseni ukuba imveliso yokugqibela iyahlangabezana nococeko olufunekayo kunye nemigangatho yomgangatho.

Ngoku ukuba unokuqonda okungcono malunga nendlela i-isopropanol eveliswa ngayo kwi-acetone, unokuyiqonda indlela eyinkimbinkimbi yale nkqubo yokuguqulwa kwemichiza. Inkqubo idinga indibaniselwano yeendlela zombini kunye neekhemikhali ukuba zenzeke ngendlela elawulwayo ukuvelisa i-isopropanol ephezulu. Ukongeza, ukusetyenziswa kwee-catalysts, ezifana ne-palladium okanye iplatinam, kudlala indima ebalulekileyo ekuphuculeni ukusebenza kakuhle kokuphendula.
