Isopropanolyog ib qho kev siv tshuaj hnyav heev, thiab nws cov ntaub ntawv raw yog muab los ntawm cov fossil fuels.Cov khoom siv raw tshaj plaws yog n-butane thiab ethylene, uas yog muab los ntawm cov roj crude.Tsis tas li ntawd, isopropanol kuj tuaj yeem tsim los ntawm propylene, ib qho khoom nruab nrab ntawm ethylene.

Cov txheej txheem tsim tawm ntawm isopropanol yog qhov nyuaj, thiab cov khoom siv raw yuav tsum tau ua raws li cov tshuaj tiv thaiv thiab kev ua kom huv huv kom tau txais cov khoom xav tau.Feem ntau, cov txheej txheem tsim muaj xws li dehydrogenation, oxidation, hydrogenation, sib cais thiab purification, thiab lwm yam.

Ua ntej, n-butane lossis ethylene yog dehydrogenated kom tau propylene.Tom qab ntawd, propylene yog oxidized kom tau acetone.Tom qab ntawd Acetone yog hydrogenated kom tau isopropanol.Thaum kawg, isopropanol xav tau kev sib cais thiab kev ua kom huv si kom tau txais cov khoom purity siab.

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

Cov khoom siv raw rau isopropanol ntau lawm yog tsim los ntawm cov fossil fuels, uas tsis tsuas yog siv cov khoom siv txuas ntxiv dua tshiab xwb tab sis kuj ua rau muaj teeb meem ib puag ncig.Yog li ntawd, nws yog ib qho tsim nyog los tsim cov khoom siv tshiab thiab cov txheej txheem tsim khoom kom txo tau kev siv cov fossil fuels thiab ib puag ncig muaj kuab paug.Tam sim no, qee cov kws tshawb fawb tau pib tshawb nrhiav kev siv cov khoom siv txuas ntxiv dua tshiab (biomass) ua cov khoom siv raw rau isopropanol ntau lawm, uas tuaj yeem muab txoj hauv kev tshiab rau kev txhim kho kom ruaj khov ntawm isopropanol kev lag luam.
