DEG inogadzirwa nechidimbu hydrolysis ye ethylene oxide. Zvichienderana nemamiriro ezvinhu, huwandu hwakasiyana hweDEG uye hunoenderana glycols hunogadzirwa. Chigadzirwa chinoguma maviri ethylene glycol mamorekuru akabatanidzwa ne ether bond.
"Diethylene glycol inotorwa se-co-product ine ethylene glycol (MEG) uye triethylene glycol. Indasitiri inowanzoshanda kuti iwedzere kugadzirwa kweMEG. Ethylene glycol ndiyo yakawanda kwazvo yezvigadzirwa zveglycol mune zvakasiyana-siyana zvekushandisa. Kuwanika kweDEG. zvinoenderana nekudiwa kwezvinobva pachigadzirwa chekutanga, ethylene glycol, kwete pane DEG musika zvinodiwa."

Inoshandiswa segasi dehydrating agent uye aromatics extraction solvent, inoshandiswawo se textile lubricant, softener uye finishing agent, pamwe ne plasticizer, humidifier, sizing agent, nitrocellulose, resin uye grease solvent. |
Diethylene glycol inoshandiswa mukugadzirwa kwemafuta epolyester akazara uye asina kukwana, polyurethanes, uye plasticizers.DEG inoshandiswa sechivako chekuvaka mune organic synthesis, eg ye morpholine uye 1,4-dioxane. Iyo inonyungudutsa ye nitrocellulose, resins, dhayi, oiri, uye mamwe organic komisheni. Inoita humectant yefodya, cork, inki yekudhinda, uye glue.Iri zvakare chikamu mubrake fluid, lubricant, wallpaper strippers, artificial fog uye haze solutions, nemafuta ekudziya/kubikisa. lotions, deodorants), DEG inowanzotsiviwa neakasarudzwa diethylene glycol ethers. A dilute solution ye diethylene glycol inogonawo kushandiswa se cryoprotectant; zvisinei, ethylene glycol inonyanya kushandiswa. Yakawanda ethylene glycol antifreeze ine mashoma muzana diethylene glycol, iripo seyakagadzirwa nekugadzirwa kwe ethylene glycol.
