Ethylene glycol tseem hu ua glycol, 1,2- ethylene glycol, lossis piv txwv li rau luv luv. Nws cov mis mis yog (ch2oh) 2, thiab nws yog qhov yooj yim teev. Ethylene glycol yog ib qho tsis muaj kob, tsw ntxhiab, qab zib-kua nrog cov tsiaj tsawg rau cov tsiaj. Ethylene glycol yog miscible nrog dej thiab acetone, tab sis muaj solubility uas tsis muaj kev ua kom muaj kev pab. Nws yog siv los ua cov kuab tshuaj, cov tshuaj tiv thaiv, thiab cov khoom siv raw rau cov khoom siv hluavtaws polyester. Ethylene Glycol Polymer Polyethylene Glycol (Peg) yog theem hloov catalyst thiab kuj yog siv rau cell fusion; nws nitrate ester yog tawg.
