Safety Profile

The pure material and concentrated solutions are potenially explosive. Ignites in air at 130°C. The flame temperature in OXYGEN can reach 4700°C. When heated to decomposition it emits toxic fumes of CN⁻ and NO_x. See also NITRILES and ACETYLENE COMPOUNDS and ALKYNES.

Specification

Dicyanoacetylene ,its cas register number is 1071-98-3. It also can be called But-2-ynedinitrile ;and Carbon subnitride . It has a linear structure with alternating triple and single covalent bonds, and it can explode to carbon powder and nitrogen gas for its high endothermic heat of formation. As of 2006, its the detection in the interstellar medium has been impossible, because its symmetry means it has no rotational microwave spectrum.
