Succinonitrile or butanedinitrile, is an organic chemical compound, a nitrile. It has the formula NCCH2CH2CN or C4H4N2.

Properties

Chemical

Hydrogenation of succinonitrile yields putrescine.

Physical

Succinonitrile is a waxy colorless solid, that slowly turns brownish in air. It is soluble in water and alcohols.

Availability

Butanedinitrile is sold by chemical suppliers.

Preparation

Succinonitrile is mainly produced by the addition of hydrogen cyanide to acrylonitrile:[2]

CH2=CHCN + HCN → NCCH2CH2CN

Alternatively, it can also be produced by reacting 1,2-dibromoethane or 1,2-diiodoethane with potassium or sodium cyanide.[3][4]

Projects

Handling

Safety

Succinonitrile is expected to be toxic, as it's metabolized to free cyanide which is very toxic. It can be absorbed via ingestion, inhalation and skin/eye contact.[5]

Storage

In closed bottles, away from corrosive reagents.

Disposal

Should be carefully mixed with bleach. Alternatively it can be dissolved in a flammable solvent and burned in an incinerator.
