In a process for producing a nitrile compound from a corresponding aldehyde exhibited by the general formula (I) and a hydroxylamine inorganic acid salt R.sup.1 CHO (I) or from an aldoxime exhibited by the general formula (II), R.sup.2 CH.dbd.NOH (II) (in the general formulas shown hereinabove, R.sup.1 represents an aryl group having 6 to 9 carbon atoms and R.sup.2 represents an alkyl or alkenyl group having 1 to 9 carbon atoms or an aryl group having 6 to 9 carbon atoms), a process, wherein water produced in the reaction is azeotropically distilled out of the reaction system with the aid of a solvent which makes an azeotropic mixture with water. The nitrile compound is useful as an important intermediate for the synthesis of pharmaceuticals or pesticides.
