The reactivity of epoxyethane Ring strain The reason that epoxyethane is so reactive is that bonding pairs in the ring of atoms in the molecule are forced very close together. The bond angles are about 60Â° rather than about 109.5Â° when carbon atoms normally form single bonds.hen epoxyethane reacts a carbon-oxygen bond is always broken and the ring opens up. Uses of epoxyethane Manufacture of ethane-1,2-diol (ethylene glycol) Acid catalysed hydrolysis of epoxyethane Epoxyethane reacts with water in the presence of an acid catalyst (very dilute sulphuric acid) at a temperature of about 60Â°C.
The conversion from epoxyethane to the diol takes place in two stages. First the epoxide reacts with carbon dioxide to form 1,3-dioxolan-2-one (ethene carbonate): An organophosphorus compound is used as the catalyst. Ethene carbonate is then reacted with water to form ethane-1,2-diol and regenerates carbon dioxide.igure 1 Uses of ethane-1,2-diol. By far the most important uses of the diol is in the manufacture of polyesters, particularly PET (polyehylene terephthalate), used widely for clothes and for packaging. Another important use is as a coolant in engines.
