Reactivities / Incompatibilities

Strong oxidizers such as chlorine, bromine, and fluorine; chlorosulfonic acid; oleum or sulfuric acid. May accumulate static electricial charges, and may cause ignition of its vapors.
Strong oxidizers.
Will react with water, steam, acids to produce toxic & flammable vapors.
Nitrogen-fluorine compounds are potentially explosive in contact with acetonitrile. ... A solution of an unspecified lanthanide perchlorate in acetonitrile detonated while being heated under reflux.
A mixture of acetonitrile and sulfuric acid on heating (or self-heating) to 53 deg C underwent an uncontrollable exothermic reaction to 160 deg C in a few seconds. The presence of 28 mol% of sulfur trioxide reduces the initiation temperature to about 15 deg C. Polymerization of the nitrile is suspected.
When fluorine was condensed onto acetonitrile and chlorine fluoride frozen at -196 deg C, a small explosion occurred in the reactor.
... Potentially explosive character of ... 2-cyanopropyl nitrate in acetonitrile.
Shaking a slow-reacting mixture /of dinitrogen tetraoxide, acetonitrile and indium/ caused detonation, attributed to indium-catalysed oxidation of acetonitrile.
The violent reaction which occurred on dissolution of the anhydrous salt in acetonitrile did not occur with the hydrated salt /of iron(III) perchlorate/.
Mixtures of fuming nitric acid and acetonitrile are explosive.
Latent hazards in storing and handling the explosive mixtures of perchloric acid with acetonitrile.
Reacts with oxidizing materials.
