1X W 1 3/8"

Properties:

Colourless, combustible toxic gas with a sweetish ether like odour.

Miscible in all proportions in water, methanol, acetone and Diethyl ether.

Has a tendency to spontaneously polymerise. 

The gas has a tendency to spontaneous polymerisation, which is catalysed by acids and alkalis and takes place with a large exotherm, making it an explosion risk and it should therefore be stored cool and under nitrogen. 

Ethylene oxide is obtained industrially by the oxidation of ethene with atmospheric oxygen over a silver catalyst. Sometimes the elimination of hydrogen chloride from ethylene chlorhydrin is also used.

The applications of ethylene oxide

Ethylene oxide is a reactive component used regularly in chemical syntheses plus it is used to manufacture antifreeze, solvents, plasticisers, carboxylic acids, surfactants and ethanolamines. Other downstream products of ethylene oxide are used as pharmaceuticals, plastics, textile auxiliaries and emulsifiers.

Sterilisation using ethylene oxide is also widespread and has the advantage of penetrating through packing materials and diffusing into the articles that are to be sterilised. This is used by fumigating medical products and in the medical area, it is only used for sterilising thermolabile products such as plastics, rubber, catheters and optical items. 

A distinction is made between low-pressure sterilisation mixtures with up to 90% vol./vol. Of Ethylene oxide. These gas mixtures must be withdrawn from the pressure vessels through dip-pipes that prevent a change in the composition.
