Cov mis mos molecular ntawm ethylene glycol (MEG CAS 107-21-1) yog C2H6O2. Nws yog ib qho organic compound, tseem hu ua glycol lossis dihydroxyethanol. Lub ethylene glycol molecule muaj ob lub carbon atoms, rau hydrogen atoms, thiab ob lub atoms oxygen. Nws cov yam ntxwv yam ntxwv yog tias ob pawg hydroxyl (-OH) txuas rau ob lub pa roj carbon atom, tsim cov qauv sib luag. Cov qauv no endows ethylene glycol nrog solubility zoo thiab hygroscopicity, ua rau nws siv dav hauv ntau yam kev lag luam.

Kev siv tseem ceeb ntawm Ethylene glycol (MEG CAS 107-21-1)
Ethylene glycol muaj ntau yam kev siv, suav nrog:
- Feem ntau siv los ua cov kuab tshuaj, tshuaj tiv thaiv kab mob, thiab cov khoom siv raw rau hluavtaws polyester.
- Aqueous kev daws teeb meem ntawm MEG muaj qhov chaw khov qis heev, yog li nws yog siv los ua cov tshuaj tiv thaiv kab mob.
- MEG tuaj yeem tov nrog dej hauv txhua qhov kev faib ua feem. Tom qab sib tov, lub vapor siab ntawm cov dej txias tau hloov pauv, txo qis qhov chaw khov thiab tswj xyuas cov khoom tiv thaiv zoo ntawm qhov kub thiab txias. Yog li ntawd, nws yog dav siv nyob rau hauv coolants rau tsheb thiab aircraft engine.
- 1,2-ethanediol (ethylene glycol) kuj tuaj yeem siv los ua tus neeg sawv cev ntub dej hauv cellophane, fibers, tawv, thiab nplaum.
