Cov txheej txheem tseem ceeb rau kev npaj cov dej haus ethanol muaj xws li distillation, molecular sieve adsorption, thiab tshuaj synthesis. Cov txheej txheem no zoo tshem tawm cov dej los ntawm ethanol, yielding ntshiab anhydrous ethanol. Anhydrous ethanol yog nplaim taws thiab tawg, yog li ntawd, yuav tsum tau ceev faj tshwj xeeb thaum khaws cia thiab siv. Tsis tas li ntawd, nws muaj qhov zoo solubility thiab volatility, cov khoom uas ua rau nws siv dav hauv ntau qhov chaw.
Vim nws cov purity siab thiab cov khoom tshwj xeeb, anhydrous ethanol muaj cov ntawv thov tseem ceeb hauv ntau qhov chaw:
Kev Lag Luam Tshuaj: Ua ib qho hnyav, siv hauv kev tsim thiab ua cov xim, txheej, resins, thiab lwm yam.
Kev Lag Luam Kev Kho Mob thiab Kev Noj Qab Haus Huv: Siv rau hauv kev npaj cov tshuaj tua kab mob, thiab hauv kev tsim thiab tu cov tshuaj, khoom siv kho mob, thiab lwm yam.
Kev Tshawb Fawb Txog Kev Tshawb Fawb: Raws li cov tshuaj reagent, siv ntau yam kev sim tshuaj, xws li cov organic synthesis thiab analytical testing.
Khoom noj khoom haus: Raws li tus nqa khoom rau flavorings thiab fragrances, siv los txhim kho cov saj thiab tsw ntawm zaub mov.
