Reactivities / Incompatibilities

Pure, dry, o- and hydroperoxide-free dioxane rapidly forms hydroperoxide on contact with air.
Decaborane ... forms impact sensitive mixtures with ... dioxane. ...
Since 1:1 addition /of sulfur trioxide-dioxane/ complex sometimes decomposes violently on storing at ambient temp, it should be prepared immediately before use (if refrigerated storage is not possible).
/In the reaction with triethynylaluminium/ the residue from sublimation of the complex with dioxane is explosive, and the complex should not be dried by heating.
Boron trifluoride in aq dioxane was being evaporated with nitric acid treatment (3 portions) for analysis. Final addition of perchloric acid with continued heating led to an explosion while unattended. Ring scission of dioxane to diethylene glycol and formation of diethylene glycol nitrate and/or perchlorate may have been involved.
... Can react vigorously with oxidizing materials.
Dioxane reacts with Raney nickel catalyst almost explosively above 210 deg C
Vapors may form explosive mixture with air. Vapors may form explosive mixture with air.
Incompatible materials: Oxygen, Oxidizing agents, Halogens, Reducing agents, Perchlorates., Trimethylaluminum
