Ethanol (feem ntau hu ua cawv) yog ib qho tseem ceeb organic compound nrog ntau yam kev siv thiab kev ua haujlwm. Cov hauv qab no yog cov kev siv tseem ceeb thiab kev ua haujlwm ntawm ethanol:
① Dej haus: Ethanol yog cov khoom tseem ceeb ntawm cov dej haus cawv thiab tuaj yeem tsim los ntawm kev ua kom cov suab thaj hauv cov kab mob me me.
② Tshuaj tua kab mob: Cov tshuaj ethanol 70% -75% muaj cov khoom tua kab mob zoo thiab feem ntau siv rau kev kho mob thiab kev tua kab mob hauv tsev.
③ Roj tsheb: Ethanol tuaj yeem sib xyaw ua roj av ua roj tsheb, ua lub zog rov ua dua tshiab thiab huv.
④ Cov kuab tshuaj organic: Ethanol yog cov kuab tshuaj organic zoo heev uas muaj peev xwm yaj tau ntau yam tshuaj, ua rau nws siv dav ua cov kuab tshuaj hauv kev tsim khoom lag luam thiab kev tshawb fawb.
⑤ Cov khoom siv tshuaj lom neeg: Ethanol siv tau los tsim cov khoom siv tshuaj lom neeg xws li acetaldehyde, ethyl acetate, thiab ethylamine, thiab tseem yog cov khoom siv raw rau kev tsim tshuaj, cov xim pleev xim, cov xim pleev, cov tshuaj ntxuav tes, thiab lwm yam khoom.
⑥ Siv rau hauv biology: Anhydrous ethanol siv tau los rho cov pigments los ntawm chloroplasts.
⑦ Txo qhov kub taub hau: Siv cov tshuaj ethanol 25% -50% los txo qhov kub taub hau, vim nws ua rau txias.
⑧ Kev Saib Xyuas: Cov tshuaj cawv 40%-50% siv tau los da dej rau cov neeg uas pw hauv txaj ntev.
Hauv kev xaus, ethanol ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw, suav nrog lub neej txhua hnub, kev kho mob, kev tsim khoom lag luam, thiab kev tshawb fawb.
