Use

Ethylene oxide is widely used as a sterilizingagent; as a fumigant; as a propellant; in theproduction of explosives; in the manufactureof ethylene glycol, polyethylene oxide, gly-col ethers, crown ethers, ethanolamines, andother derivatives; and in organic synthesis. It is used as fumigant for foodstuffs and textiles; to sterilize surgical instruments; agricultural fungicide. In organic syntheses, especially in the production of ethylene glycol. Starting material for the manufacture of acrylonitrile and nonionic surfactants.
