Le ʋuwɔƒewo la, ethylene glycol nye nu vevi aɖe si wozãna tsɔ tsia tsikpe nu. Eɖea tsi ƒe fafa ƒe dzoxɔxɔ dzi kpɔtɔna, si wɔnɛ be fafanu megafa le dzoxɔxɔ si bɔbɔ me o, eye wòdoa tsi ƒe dzoxɔxɔ ɖe dzi, si wɔnɛ be mɔ̃a megaxɔa dzo akpa o. Wozãa tsikpewutike si wotsɔ ethylene glycol wɔe geɖe le ʋuwo, agbatsɔʋuwo, kple dɔwɔƒewo ƒe fafamɔ̃wo me be woakpɔ egbɔ be mɔ̃a le dɔ wɔm nyuie le dzoxɔxɔ si gbɔ eme me. Tsɔ kpe ɖe eŋu la, dzoxɔxɔ ƒe liƒo nyui kple xɔxlɔ̃ ƒe ŋutete le ethylene glycol si, si ate ŋu ana fafamɔ̃wo ƒe dɔwɔwɔ nadidi ɖe edzi.
Le atikewɔƒewo la, ethylene glycol nye nu vevi aɖe si wotsɔ wɔa nu gbagbewoe. Wozãnɛ tsɔ wɔa polyethylene terephthalate (PET), si nye nu vevitɔ si wotsɔ wɔa polyester ka, aŋɔ, kple aŋetuwoe. Woate ŋu azã ethylene glycol hã atsɔ awɔ lãmenugbagbeviwo ƒe nu vovovowo abe ethylene glycol ethers, esters, kple amines ene, siwo wozãna geɖe le atike siwo wotsɔna tsia nu, nutsyɔnu, nuŋlɔtsi, kple elektrɔnik atikewo me.
Le atikewɔƒewo la, wozãa ethylene glycol abe atike si wotsɔna tsia atikewoe kple domedomenuwo ene. Ate ŋu alɔ atike ƒe akpa aɖewo, si ana atikewo nali ke eye woƒe ʋeʋẽ nanyo ɖe edzi. Tsɔ kpe ɖe eŋu la, woate ŋu azã ethylene glycol atsɔ awɔ atikewo ƒe domedomenuwo abe ethylene glycol ethers kple esters ene, siwo ŋudɔ vevi aɖe le le atikewo wɔwɔ me.
Le avɔlɔ̃ƒewo la, wozãa ethylene glycol tsɔ wɔa polyester ka. Wonya polyester kawo be ŋusẽ le wo ŋu ŋutɔ, wote ŋu nɔa te ɖe vuvu nu, eye woléa nɔnɔme nyui me ɖe asi, eye wozãa wo geɖe le awuwo, aƒeme avɔwo, kple dɔwɔƒewo ƒe avɔwo me. Ethylene glycol wɔa akpa vevi aɖe le polyester ka wɔwɔ me to nuwɔwɔ kple terephthalic acid tsɔ wɔa polyethylene terephthalate (PET), si wɔnɛ be wokpɔa polyester ka siwo le nyonyome nyuie.
Le elektrɔnikmɔ̃ɖaŋudɔwɔƒewo la, wozãa ethylene glycol abe atike si wotsɔna tsia nu kple fafa ene. Woate ŋu azãe atsɔ akɔ elektrɔnikmɔ̃wo ƒe akpa aɖewo ŋu, aɖe ɖiƒoƒo siwo le anyigba dzi kple nusiwo susɔ la ɖa.
