Isopropanolthiab ethanol yog ob hom cawv cawv uas muaj ntau daim ntawv thov hauv ntau yam lag luam.Txawm li cas los xij, lawv cov khoom thiab kev siv sib txawv heev.Hauv tsab xov xwm no, peb yuav sib piv thiab sib piv isopropanol thiab ethanol los txiav txim seb qhov twg "zoo dua".Peb yuav xav txog yam xws li kev tsim khoom, tshuaj lom neeg, solubility, flammability, thiab lwm yam.

Yuav pib, cia peb saib cov txheej txheem tsim khoom ntawm ob qho cawv no.Ethanol feem ntau yog tsim los ntawm fermentation ntawm cov suab thaj muab rho tawm los ntawm biomass, ua rau nws muaj peev xwm txuas ntxiv mus.Ntawm qhov tod tes, isopropanol yog tsim los ntawm propylene, petrochemical derivative.Qhov no txhais tau hais tias ethanol muaj qhov zoo dua nyob rau hauv cov nqe lus ntawm kev ua lwm txoj hauv kev ruaj ntseg.

Tam sim no cia peb tshawb nrhiav lawv cov tshuaj lom.Isopropanol yog tshuaj lom ntau dua li ethanol.Nws yog volatile heev thiab muaj ib tug tsawg flash point, ua rau nws muaj teeb meem hluav taws kub.Tsis tas li ntawd, kev noj cov isopropanol tuaj yeem ua rau muaj kev noj qab haus huv hnyav, nrog rau lub siab thiab lub raum kev puas tsuaj, hauv nruab nrab lub paj hlwb kev nyuaj siab, thiab txawm tias tuag taus.Yog li ntawd, thaum nws los txog rau toxicity, ethanol yog kom meej meej xaiv kev nyab xeeb.

Tsiv mus rau solubility, peb pom tias ethanol muaj ntau dua solubility hauv dej piv rau isopropanol.Cov cuab yeej no ua rau ethanol tsim nyog rau kev siv ntau yam xws li tshuaj tua kab mob, cov kuab tshuaj, thiab tshuaj pleev ib ce.Isopropanol, ntawm qhov tod tes, muaj qis solubility hauv dej tab sis yog miscible ntau nrog cov kuab tshuaj organic.Cov yam ntxwv no ua rau nws tsim nyog siv rau hauv cov xim, nplaum, thiab coatings.

Thaum kawg, cia peb xav txog qhov flammability.Ob leeg cawv yog cov nplaim taws heev, tab sis lawv cov nplaim taws yog nyob ntawm qhov concentration thiab muaj cov khoom siv hluav taws xob.Ethanol muaj qhov taw qhia qis dua thiab qhov kub ntawm qhov pib pib dua li isopropanol, ua rau nws muaj peev xwm ntes hluav taws hauv qee yam mob.Txawm li cas los xij, ob qho tib si yuav tsum tau ceev faj heev thaum siv.

Hauv kev xaus, "zoo dua" cawv ntawm isopropanol thiab ethanol nyob ntawm daim ntawv thov tshwj xeeb thiab cov khoom xav tau.Ethanol sawv tawm raws li cov kev xaiv uas nyiam nyob rau hauv cov nqe lus ntawm sustainability thiab kev nyab xeeb.Nws tsis tshua muaj toxicity, siab solubility nyob rau hauv dej, thiab qhov chaw txuas ntxiv ua rau nws haum rau ntau yam kev siv los ntawm cov tshuaj tua kab mob mus rau roj.Txawm li cas los xij, rau qee cov ntawv thov kev lag luam uas yuav tsum muaj cov khoom siv tshuaj lom neeg, isopropanol yuav yog qhov kev xaiv zoo dua.Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum tau siv ob qho tib si cawv nrog kev ceev faj heev vim tias lawv yog cov nplaim hluav taws kub heev thiab tuaj yeem ua rau muaj kev phom sij yog tias tsis siv.
