Ethylene Glycol: Definition, Chemical Reaction, Uses and Examples
网页Ethylene glycol is the most abundantly produced diol. It is one of the monomers of polyethylene terephthalate. Ethylene glycol has been synthesized by the oxidation of ethylene with \(O_2\) to ethylene oxide and the hydration of ethylene oxide to ethylene glycol. The molecular weight or molar mass of ethylene glycol is 62.07 gram per mole.
