WebEthylene intermediate of ethylene oxide glycol used (EO) in and the is other a production versatile oxide intermediate used in the production of ethylene glycol and other oxide derivatives. It is also used to a lesser extent as a sterilant for medical sup-plies and as fumigant for spices. EO has been shown to be mutagenic in several test systems. WebPropylene oxide (PO) is made either by the chlorohydrin process or the hydroperoxide process. The chlorohydrin process needs lime or cell liquor for neutralization; in the latter case, the PO plant is virtually integrated with a chlorine plant. The hydroperoxide process uses isobutane or ethylbenzene to coproduce t-butyl alcohol or styrene.
