Isopropanolndi madzi opanda mtundu, oyaka omwe amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana monga zosungunulira, mphira, zomatira, ndi zina. Imodzi mwa njira zazikulu zopangira isopropanol ndi kudzera mu hydrogenation ya acetone. M'nkhaniyi, tikambirana mozama za ndondomekoyi.

Gawo loyamba pakusintha kwa acetone kukhala isopropanol ndi kudzera mu hydrogenation. Izi zimatheka pochita acetone ndi mpweya wa haidrojeni pamaso pa chothandizira. Ma reaction equation panjira iyi ndi:

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

Chothandizira chomwe chimagwiritsidwa ntchito pochita izi nthawi zambiri chimakhala chitsulo cholemekezeka monga palladium kapena platinamu. Ubwino wogwiritsa ntchito chothandizira ndikuti umachepetsa mphamvu yoyambitsa yomwe ikufunika kuti zomwe zikuchitika zipitirire, ndikuwonjezera mphamvu zake.

Pambuyo pa sitepe ya hydrogenation, mankhwalawa ndi osakaniza a isopropanol ndi madzi. Chotsatira chotsatirachi chimaphatikizapo kulekanitsa zigawo ziwirizi. Izi zimachitika kawirikawiri pogwiritsa ntchito njira za distillation. Kuwira kwa madzi ndi isopropanol ndi pafupi wina ndi mzake, koma kupyolera mu ma distillations angapo, akhoza kulekanitsidwa bwino.

Madzi akachotsedwa, mankhwalawa ndi isopropanol yoyera. Komabe, isanayambe kugwiritsidwa ntchito pazinthu zosiyanasiyana, ingafunike kutsata njira zina zoyeretsera monga kutaya madzi m'thupi kapena hydrogenation kuchotsa zotsalira zilizonse zotsalira.

Njira yonse yopangira isopropanol kuchokera ku acetone imaphatikizapo njira zitatu zazikulu: hydrogenation, kupatukana, ndi kuyeretsedwa. Gawo lililonse limakhala ndi gawo lofunikira pakuwonetsetsa kuti chomaliza chikukwaniritsa chiyero ndi mikhalidwe yomwe mukufuna.

Tsopano kuti mukumvetsa bwino momwe isopropanol imapangidwira kuchokera ku acetone, mukhoza kuyamikira chikhalidwe chovuta kwambiri cha kusintha kwa mankhwala. Njirayi imafuna kuphatikiza kwa thupi ndi mankhwala kuti zichitike mwadongosolo kuti apereke isopropanol yapamwamba. Kuphatikiza apo, kugwiritsa ntchito zopangira, monga palladium kapena platinamu, zimathandizira kwambiri pakuwongolera magwiridwe antchito.
