Isopropanolchinhu chakajairwa organic musanganiswa une mashandisirwo akasiyana siyana, anosanganisira mishonga inouraya utachiona, zvinonyungudutsa, uye makemikari mbishi zvinhu. Iine huwandu hwakawanda hwekushandisa muindasitiri uye hupenyu hwezuva nezuva. Nekudaro, kunzwisisa maitiro ekugadzira isopropanol kwakakosha zvikuru kuti isu tinzwisise zviri nani zvimiro nemashandisirwo ayo. Ichi chinyorwa chinopa sumo yakadzama yekugadzirwa kweiyo isopropanol uye nenyaya dzayo dzakabatana.

Muviri mukuru:

1.Synthesis nzira ye isopropanol

Isopropanol inonyanya kugadzirwa ne hydration ye propylene. Propylene hydration ndiyo maitiro ekuita propylene nemvura kuti ibudise isopropanol pasi pechiito che catalyst. Catalysts inoita basa rakakosha mukuita uku, sezvo vachigona kukurumidza kuita maitiro uye kugadzirisa kusarudzika kwechigadzirwa. Parizvino, macatalyst anowanzo shandiswa anosanganisira sulfuric acid, alkali metal oxides, uye ion exchange resins.

2.Kunobva propylene

Propylene inonyanya kubva kumafuta ezvicherwa semafuta uye gasi rechisikigo. Nokudaro, nzira yekugadzira isopropanol inobva kune imwe nzvimbo pamafuta emafuta. Nekudaro, nekuwedzera kwekuziva nezvekuchengetedzwa kwezvakatipoteredza uye kuvandudzwa kwesimba rinogoneka, vanhu vari kutsvaga nzira nyowani dzekugadzira propylene, senge kuburikidza nekuvirisa kwebiological kana makemikari synthesis.

3.Manufacturing process flow

Nzira yekugadzira isopropanol inonyanya kusanganisira matanho anotevera: propylene hydration, catalyst recovery, kupatsanurwa kwechigadzirwa, uye kunatswa. Propylene hydration inoitika pane imwe tembiricha uye kudzvanywa, panguva iyo catalyst inowedzerwa kune musanganiswa wepropylene nemvura. Mushure mekuita kwapera, iyo catalyst inoda kudzoserwa kudzikisa mutengo wekugadzira. Kuparadzaniswa kwechigadzirwa uye kunatsiridza ndiyo nzira yekuparadzanisa isopropanol kubva musanganiswa wekuita uye kuigadzirisa kuti uwane chigadzirwa chepamusoro.

Mhedziso:

Isopropanol inokosha organic compound ine kushandiswa kwakawanda. Iyo yekugadzira maitiro inonyanya kusanganisira iyo hydration reaction yepropylene, uye iyo catalyst inoita basa rakakosha mukuita uku. Nekudaro, kuchine dzimwe nyaya nemhando yecatalyst inoshandiswa mukugadzirwa kweisopropanol uye kunobva propylene, sekusvibiswa kwezvakatipoteredza uye kushandisa zviwanikwa. Naizvozvo, isu tinofanirwa kuenderera mberi nekuongorora maitiro matsva ekugadzira uye matekinoroji kuti tiwane girinhi, inoshanda, uye inoenderera kugadzirwa kweisopropanol.
