IsoPropanolYog ib qho dav muaj cov kuab tshuaj muaj zog, thiab nws cov ntaub ntawv raw yog feem ntau yog muab los ntawm pob txha pob zeb. Cov ntaub ntawv raw feem ntau yog n-butane thiab ethylene, uas muab tau los ntawm cov roj nyoos. Tsis tas li ntawd, isopropanol kuj tseem tuaj yeem suav los ntawm Propylene, cov khoom nruab nrab ntawm ethylene.

Cov txheej txheem ntau lawm ntawm isopropanol yog cov nyom, thiab cov ntaub ntawv raw yuav tsum tau yauv cov tshuaj lom neeg thiab cov kauj ruam lim kom tau txais cov khoom xav tau. Feem ntau, cov txheej txheem ntau lawm suav nrog dehydrogenation, oxidation, hydrogenation, sib cais thiab kev ua kom huv thiab lwm yam.

Ua ntej, N-Butane lossis ethylene yog lub dehydrogenated kom tau Propylene. Tom qab ntawd, propylene yog oxidized kom tau acetone. Acetone yog ces hydrogenated kom tau isopropanol. Thaum kawg, isopropanol xav tau kev sib cais thiab cov kauj ruam lim kom tau txais cov khoom siab purity.

Ib qho ntxiv, isopropanol kuj tseem tuaj yeem ua cov khoom siv los ntawm lwm cov ntaub ntawv nyoos, xws li qab zib thiab biomass. Txawm li cas los xij, cov ntaub ntawv raw no tsis dav siv vim lawv cov txiaj ntsig qis thiab tus nqi siab.

Cov ntaub ntawv raw rau isopropanol ntau lawm feem ntau yog muab los ntawm pob txha roj, uas tsis tsuas yog haus cov peev txheej tsis nruab ntxiv tab sis kuj tseem ua teeb meem ib puag ncig. Yog li ntawd, nws yog qhov tsim nyog los tsim cov ntaub ntawv raw tshiab thiab cov txheej txheem ntau lawm los txo cov tshuaj txhuam hniav thiab ib puag ncig cov pa paug dawb. Tam sim no, qee cov kws tshawb nrhiav tau pib tshawb nrhiav kev siv cov khoom siv tshiab ntxiv rau kev tsim kho tshiab ntawm isopropanol kev lag luam.
