Ethylene glycol, oo sidoo kale loo yaqaan glycol, waa aliphatic diol-ka ugu fudud. Waxay leedahay sifooyinka kiimikada ee aalkolada, sida awoodda ay u leedahay inay soo saarto ethers iyo esters-ka, waa la oxidin karaa si loo soo saaro aldehydes ama asiidhyo, waxayna isku milmi kartaa si loo soo saaro ethers.

Muuqaal: dareere aan midab lahayn, hufan, oo leh viscous.

Isticmaalka: Ethylene glycol waxaa inta badan loo isticmaalaa sidii walxo ceeriin ah oo loogu talagalay fiilooyinka polyester-ka waxaana sidoo kale loo isticmaalaa resins-ka kale ee polyester-ka, resins-ka polyester-ka ee aan dheregsanayn, iyo rinjiyada polyester-ka ee 1730. Noocyo kala duwan oo surfactants ah ayaa laga soo saari karaa ethylene glycol iyo polyethylene glycol. Isku-darka dinitro, dinitroethylene glycol, waa wax qarxa. Ethylene glycol wuxuu hoos u dhigi karaa barta barafowga ee xalalka biyaha sidaa darteed waxaa badanaa loo isticmaalaa sidii anti-baraf.
