1, 4 Dioxane
1,4-Dioxane, often simply 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. Dioxane is used mainly 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 primarily used as a stabilizer for 1,1,1-trichloroethane for storage and transport in aluminium containers. Normally aluminium is protected by a passivating oxide layer, but when these layers are disturbed, highly reactive metallic aluminium is exposed to the chlorocarbon. This aluminium reacts with 1,1,1-trichloroethane to givealuminium trichloride, which in turn catalyses the dehydrohalogenation of the remaining 1,1,1-trichloroethane to vinylidene chloride and hydrogen chloride. Reflecting its properties as a ligand, dioxane "poisons" the aluminum trichloride catalyst, by formation of an adduct. Apart from its use as a stabilizer, dioxane is used in a variety of applications as a solvent, e.g. in inks and adhesives.
