Dioxane is used in a variety of applications as a versatile [[aprotic solvent]], e. g. for inks, adhesives, and cellulose esters.<ref name=weiss>Klaus Weissermel, Hans-Jürgen Arpe (2003) "Industrial Organic Chemistry".

While diethyl ether is rather insoluble in water, dioxane is [[miscible]] and in fact is [[hygroscopic]]. At standard pressure, the mixture of water and dioxane in the ratio 17.9:82.1 by mass is a positive [[azeotrope]] that boils at 87.6 C.<ref>Schneider, C. H.; Lynch, C.
