Safety Description:An unstable material. It explodes on impact or heating to 100°C. If warmed in air or oxygen it explodes on subsequent contact with acetylene. The sensitivity of the acetylide when precipitated from solution increases with acidity of the solution. It ignites on contact with chlorine; bromine vapor; or finely divided iodine. Reaction with silver nitrate solutions produces a sensitive, explosive mixture of silver acetylide and silver. When heated to decomposition it emits acrid smoke and fumes.
