Isopropanolndi wamba organic pawiri ndi ntchito zosiyanasiyana, kuphatikizapo mankhwala, zosungunulira, ndi mankhwala zipangizo. Ili ndi ntchito zambiri m'makampani komanso moyo watsiku ndi tsiku. Komabe, kumvetsetsa njira yopangira isopropanol ndikofunikira kwambiri kuti timvetsetse bwino zomwe zimapangidwira komanso ntchito zake. Nkhaniyi ifotokoza mwatsatanetsatane momwe amapangira isopropanol ndi zovuta zake.

Thupi lalikulu:

1.Synthesis njira ya isopropanol

Isopropanol imapangidwa makamaka ndi hydration ya propylene. Propylene hydration ndi njira yochitira propylene ndi madzi kupanga isopropanol pansi pa chothandizira. Ma catalysts amagwira ntchito yofunika kwambiri pochita izi, chifukwa amatha kufulumizitsa kuchuluka kwa momwe zinthu zikuyendera komanso kusintha kusankha kwazinthu. Pakalipano, zopangira zomwe zimagwiritsidwa ntchito kwambiri ndi sulfuric acid, alkali metal oxides, ndi ma ion exchange resins.

2.Gwero la propylene

Propylene makamaka imachokera ku zinthu zakale monga mafuta ndi gasi. Choncho, kupanga isopropanol kumadalira pamlingo wina pa mafuta oyaka. Komabe, ndi chidziwitso chowonjezeka cha chitetezo cha chilengedwe ndi chitukuko cha mphamvu zowonjezera, anthu akuyang'ana njira zatsopano zopangira propylene, monga kudzera mu fermentation yachilengedwe kapena kaphatikizidwe ka mankhwala.

3.Manufacturing process flow

Njira yopangira isopropanol imaphatikizapo njira zotsatirazi: propylene hydration, catalyst recovery, kulekanitsa mankhwala, ndi kuyenga. Propylene hydration imapezeka pa kutentha kwina ndi kupanikizika, pamene chothandizira chimawonjezeredwa kusakaniza kwa propylene ndi madzi. Zomwezo zikamalizidwa, chothandizira chiyenera kubwezeretsedwanso kuti chichepetse ndalama zopangira. Kulekanitsa katundu ndi kukonzanso ndi njira yolekanitsa isopropanol kuchokera kusakaniza kosakanikirana ndikuwongolera kuti mupeze mankhwala oyeretsedwa kwambiri.

Pomaliza:

Isopropanol ndi yofunika organic pawiri ndi ntchito zambiri. Njira yopangira zinthu makamaka imakhudza momwe ma hydration amachitira propylene, ndipo chothandizira chimakhala ndi gawo lalikulu pakuchita izi. Komabe, pali zovuta zina ndi mtundu wa chothandizira chomwe chimagwiritsidwa ntchito popanga isopropanol ndi gwero la propylene, monga kuwononga chilengedwe komanso kugwiritsa ntchito zinthu. Choncho, tiyenera kupitiriza kufufuza njira zatsopano zopangira ndi matekinoloje kuti tipeze zobiriwira, zogwira mtima, komanso zokhazikika za isopropanol.
