Description

General description

Isobutyronitrile (IBN) is an aliphatic nitrile. It is widely used as a solvent for electrochemical analyses. IBN can be prepared from amino acids, via anaerobic degradation. It undergoes oxidative dehydrogenation in the presence of an iron phosphate catalyst to afford methacrylonitrile, acetone, carbon oxides and traces of cyanic acid.
