I-ethylene glycol, ekwaziwa ngokuba yi-glycol, yeyona diol ilula kakhulu. Ineempawu zeekhemikhali ze-alcohols, ezinje ngokukwazi ukuvelisa ii-ether kunye nee-esters, ingaxutywa ukuze ivelise ii-aldehydes okanye ii-asidi, kwaye inokuxinana ukuze ivelise ii-ether.

Inkangeleko: ulwelo olungenambala, olucacileyo, olunencasa.

Ukusetyenziswa: I-Ethylene glycol isetyenziswa kakhulu njengezinto eziluhlaza kwiifayibha ze-polyester kwaye ikwasetyenziswa nakwezinye ii-polyester resins, ii-polyester resins ezingagcwaliyo, kunye neepeyinti ze-polyester ze-1730. Iindidi ezahlukeneyo ze-surfactants zinokufunyanwa kwi-ethylene glycol kunye ne-polyethylene glycol. I-dinitro compound yayo, i-dinitroethylene glycol, iyaqhuma. I-Ethylene glycol inokunciphisa iqondo lokuqandisa lezisombululo zamanzi kwaye ke ngoko isetyenziswa njenge-antifreeze.
