IsopropanolIcho chisina ruvara, chinopisa, chinopisa chinwiwa chinoshandiswa zvakanyanya mumasango akasiyana-siyana senge solvent, rubber, anomisheni, uye vamwe. Imwe yenzira dzekutanga dzekugadzira isopropanol iri kuburikidza nehydrogenation yeacetone. Munyaya ino, isu tichakurudzira zvakadzama kuita izvi.

Nhanho yekutanga mukushandurwa kweacetone kune isopropanol iri kuburikidza ne hydrogenation. Izvi zvinowanikwa nekuita acetone ne hydrogen gasi pamberi pechikepe. Iyo yekugadzirisa equation yeichi maitiro ndeye:

2Ch3c (o) Ch3 + 3H2 -> 2Ch3chHCH3

Iyo Catalyst inoshandiswa mune iyi maitiro inowanzoita simbi yakanaka senge palladium kana platinamu. Kubatsira kwekushandisa CATALYST ndeyekuti iyo inoderedza iyo esimba simba rinodiwa kuti maitiro aenderere mberi, achiwedzera kushanda kwayo.

Mushure meiyo hydrogenation nhanho, chigadzirwa chinokonzeresa musanganiswa weIsopropanol nemvura. Nhanho inotevera iri muchirongwa ichi chinosanganisira kupatsanura zvikamu zviviri izvi. Izvi zvinowanzoitwa uchishandisa nzira dze distillation. Pfungwa dzinobikwa dzemvura neIsopropanol dzakabatana kune mumwe nemumwe, asi kuburikidza nemutevedzeri wezvevatevedzeri disctions, ivo vanogona kuparadzaniswa zvinobudirira.

Kana mvura yabviswa, chigadzirwa chinokonzeresa ndeye ipropropanol. Nekudaro, zvisati zvaitika zvinogona kushandiswa mukushandisa kwakasiyana-siyana, zvinogona kuda kuwedzera matanho ekuchenesa senge kushomeka kana hydrogenation kuti ubvise chero kusara kwakasara.

Maitiro ese ekugadzira isopropanol kubva kuacetone inosanganisira matanho matatu makuru: hydrogenation, kupatsanurwa, uye kucheneswa. Nhanho imwe neimwe inotora basa rakakosha mukuona kuti chigadzirwa chekupedzisira chinosangana nekuchena kwaunoda uye maitiro emhando yepamusoro.

Zvino zvaunonzwisisa zviri nani kuti haapiwepropanil anogadzirwa kubva kuacetone, unogona kukoshesa chimiro chakaomarara chechirongwa ichi chekushandurwa kwemakemikari. Maitiro acho anoda musanganiswa wezvese zvepanyama uye makemikari maitiro kuti zviitike nenzira inodzorwa yekuteedzera yakakwirira-mhando isopropanol. Pamusoro pezvo, kushandiswa kwekutengesa, senge palladium kana platinum, inotamba yakakosha basa mukuvandudza kushanda kwekuita.
