Butyronitrile or butanenitrile or propyl cyanide, is a nitrile with the formula C3H7CN. This colorless liquid is miscible with most polar organic solvents.
Uses
[edit]Butyronitrile is mainly used as a precursor to the poultry drug amprolium.[4]
It also has recognized use in the synthesis of Etifelmine.
Synthesis
[edit]Butyronitrile is prepared industrially by the ammoxidation of n-butanol:
- C3H7CH2OH + NH3 + O2 → C3H7CN + 3 H2O
Occurrence in space
[edit]Butyronitrile has been detected in the Large Molecule Heimat in Sagittarius B2 cloud along with other complex organic molecules.[5]
