Cinnamonitrile was synthesized directly from cinnamaldehyde and hydroxylamine hydrochloride in the presence of ZnO as the catalyst under solvent-free conditions. The results showed that the yield of cinnamonitrile is up to 90 . 2% when the molar ratio of cinnamaldehyde to hydroxylamine hydrochloride is 1:1 . 5 ,the amount of catalyst is 6%( based on the mass of cinnamaldehyde ),reaction temperature is 120 ℃ and the reaction time is 1 h. ZnO is a readily available and environment-friendly catalyst.
