Sharaxaada Alaabta
Isticmaalka ugu weyn ee ethylene glycol waa sida wakiilka ka-hortagga barafka ee qaboojiyaha tusaale ahaan, baabuurta iyo nidaamyada qaboojiyaha kuwaas oo dhigaya qaboojiyaha ama hawo-bixiyeyaasha dibadda ama waa inay ku qaboojiyaan heerkulka qaboobaha ee biyaha. Nidaamyada kuleyliyaha/qaboojinta dhulka, ethylene glycol waa dareeraha qaada kulaylka iyadoo la adeegsanayo bamka kulaylka geothermal. Ethylene glycol midkood waxa uu tamar ka helaa isha ( harada, badweynta, ceelka biyaha) ama waxa ay u daadisaa kulaylka saxanka, iyada oo ku xidhan haddii nidaamka loo isticmaalo kulaylinta ama qaboojinta.
Ethylene glycol saafi ah ayaa leh awood kulayl gaar ah qiyaastii kala badh biyaha. Markaa, iyadoo la bixinayo ilaalinta baraf iyo bar karkarinta oo kordhay, ethylene glycol waxay hoos u dhigtaa awoodda kulaylka gaarka ah ee isku dhafka biyaha marka loo eego biyaha saafiga ah. A 1:1 isku dhafka cufku wuxuu leeyahay awood kuleyl gaar ah oo ku saabsan 3140 J/(kg·°C) (0.75 BTU/(lb·°F)), saddex meelood meel ahaan biyaha saafiga ah, sidaas darteed waxay u baahan tahay kororka heerka socodka isla- isbarbardhigga nidaamka biyaha.

Codsiga
| Loo isticmaalo soosaar ahaan, sida birta, cobalt, cusbo naxaas ah, soosaarista isku dhafan ee diphenylcarbamide dihydrazine. Si loo kala saaro koloridhida lithium ee chlorides birta alkali ah. |
Isku darka ethylene glycol biyo waxay bixisaa faa'iidooyin dheeraad ah si ay u qaboojiyaha iyo xal antifreeze, sida ka hortagga daxalka iyo xaalufka acid, iyo sidoo kale la joojiyo koritaanka microbes iyo fungi. Isku darka ee glycol ethylene iyo biyaha mararka qaarkood si aan rasmi ahayn loo tixraaco warshadaha sida glycol concentrates, xeryahooda, isku darka, ama xalalka.
Warshadaha caagga ah, ethylene glycol waa horudhac muhiim u ah fiilooyinka polyesterka iyo resins. Polyethylene terephthalate, oo loo isticmaalo samaynta caagagga caaga ah ee cabitaannada fudud, ayaa laga diyaariyey ethylene glycol.
Faa'iidada
Tayada badeecada, tiro ku filan, gaarsiinta wax ku oolka ah, tayada sare ee adeega Waxay leedahay faa'iido ka badan amine la mid ah, ethanolamine, in diirada sare loo isticmaali karo isla awooda daxalka. Tani waxay u ogolaanaysaa sifeeyayaasha inay xoqaan hydrogen sulfide oo ah heerka amiinada wareega hoose ee isticmaalka tamarta guud.
