Isopropanolimvura isina ruvara, inobvira moto inoshandiswa zvakanyanya mumaindasitiri akasiyana senge zvinonyungudutsa, marabha, zvinonamira, nezvimwe. Imwe yenzira dzekutanga dzekugadzira isopropanol ndeye hydrogenation yeacetone. Muchinyorwa chino, tichazama zvakadzama mukuita uku.
Nhanho yekutanga mukushandurwa kweacetone kuita isopropanol ndeye hydrogenation. Izvi zvinowanikwa kuburikidza nekuita acetone nehydrogen gasi pamberi pechinhu chinokonzeresa. Mhinduro equation yeiyi process ndeiyi:
2CH3C(O)CH3 + 3H2 -> 2CH3CHOHCH3
Iyo catalyst inoshandiswa mukuita uku inowanzoita simbi yakanaka senge palladium kana platinamu. Kubatsira kwekushandisa catalyst ndeyekuti inoderedza activation simba rinodiwa kuti mhinduro ienderere mberi, ichiwedzera kushanda kwayo.
Mushure mehanho yehydrogenation, chigadzirwa chinoguma musanganiswa we isopropanol nemvura. Nhanho inotevera mukuita inosanganisira kupatsanura zvikamu zviviri. Izvi zvinonyanya kuitwa uchishandisa distillation nzira. Iyo yekubikira yemvura uye isopropanol iri padyo kune mumwe nemumwe, asi kuburikidza neakatevedzana madiki distillations, anogona kunyatsopatsanurwa.
Kana mvura ichinge yabviswa, chigadzirwa chinoguma chakachena isopropanol. Zvisinei, isati yagona kushandiswa mune zvakasiyana-siyana, ingada kuenderera mberi nhanho dzekucheneswa senge dehydration kana hydrogenation kubvisa chero tsvina yasara.
Iyo yakazara maitiro ekugadzira isopropanol kubva kuacetone inosanganisira matanho makuru matatu: hydrogenation, kupatsanurwa, uye kucheneswa. Danho rega rega rinoita basa rakakosha mukuona kuti chigadzirwa chekupedzisira chinozadzisa kuchena kunodiwa uye zvemhando yepamusoro.
Iye zvino zvauri kunzwisisa zviri nani kuti isopropanol inogadzirwa sei kubva kuacetone, unogona kuonga maitiro akaoma eiyi kemikari yekushandura nzira. Iyo nzira inoda musanganiswa wezvese muviri uye kemikari kuita kuti zviitike nenzira inodzorwa kuti ibudise yemhando yepamusoro isopropanol. Pamusoro pezvo, kushandiswa kwezvinokonzeresa, senge palladium kana platinamu, kunoita basa rakakosha mukusimudzira kugona kwekuita.
