Dioxane

• 1,4-Dioxane, often called dioxane because the 1,2 and 1,3 isomers of dioxane are rare, is a heterocyclic organic compound. It is a colorless liquid with a faint sweet odor similar to that of diethyl ether. It is classified as an ether. 
• It is a volatile organic compound that has a moderate vapor pressure and has a specific gravity of 1.033. It is very mobile and only weakly retarded by sorption during transport.
• This colorless liquid is mainly used as a stabilizer for the solvent trichloroethane. It is an occasionally used solvent for a variety of practical applications as well as in the laboratory.
• Dioxane is produced by the acid-catalysed dehydration of diethylene glycol, which in turn arises from the hydrolysis of ethylene oxide.
