Ethylene oxide (EO) is a useful intermediate in chemical manufacture, despite being a deadly product with about half the explosive content of TNT. It is also a suspected carcinogen. EO is primarily used in the production of ethylene glycol, which is in turn utilised mainly in the making of polyesters and antifreeze. Globally, some 63% of EO is converted to mono ethylene glycol (MEG), with a further 7% going into other glycols.
EO is a colourless gas at ambient temperatures which condenses when cooled to a colourless mobile liquid boiling at 10.4ºC. The vapours are extremely flammable and toxic if inhaled.
