Ethylene glycol CAS 107-21-1

Ethylene glycol, oo sidoo kale loo yaqaan glycol, waa aliphatic diol-ka ugu fudud. Waxay leedahay sifooyin kiimiko ah oo alkohol ah, sida awoodda lagu abuuro ethers iyo esters, in la oksaydhiyo si loo soo saaro aldehydes ama asiidhyo, iyo in la isku ururiyo si loo soo saaro ethers. Waxa kale oo lagu beddeli karaa halogens. Marka lala falgalo acyl chlorides ama acid anhydrides, diesters-ka guud ahaan waa la sameeyaa. Marka la kululeeyo iyadoo ay joogaan kataliye (manganese dioxide, aluminium oxide, zinc oxide ama sulfuric acid), waxaa lagu fuuq bixi karaa gudaha molecularly ama intermolecularly si loo soo saaro cyclic ethylene glycol acetal, kaas oo la falgala nitric acid si loo soo saaro ethylene glycol dinitrate (wax qarxa). Ethylene glycol waa walxo cayriin ah oo loogu talagalay soo saarista resins polyester, resins alkyd, iyo fiilooyinka polyester-ka. Waxa kale oo loo isticmaalaa qaboojiyaha ka hortagga barafowga baabuurta iyo matoorka diyaaradaha.

Isticmaalka Ethylene glycol waxaa inta badan loo isticmaalaa 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-ga dinitroethylene glycol waa wax qarxa. Ethylene glycol wuxuu hoos u dhigi karaa barta barafka ee xalalka biyaha, sidaas darteed waxaa badanaa loo isticmaalaa sidii wakiil ka hortagga barafowga.
