Epoxyethane (Ethylene oxide)

Epoxyethane (ethylene oxide EO) is a colourless gas at room temperature The bonds in the ring are easily broken so epoxyethane is very reactive This together with it being made directly from ethene (ethylene) a readily available feedstock makes it an extremely important intermediate in the manufacture of many useful chemicals Uses of epoxyethane (ethylene oxide) The principal use of

Epoxyethane reacts with water in the presence of an acid catalyst (very dilute sulphuric acid) at a temperature of about 60C Ethane-1 2-diol is produced A large excess of water is used to try to prevent the product from reacting with the original epoxyethane Ethane-1 2-diol is an alcohol (because it contains simple -OH groups) and alcohols react with epoxyethane (see below) Even in the
