Ammoxidation of benzaldehyde by using oxygen gas as an oxidant was examined in methanolic solution at 30°, in the presence of cupric chloride and sodium methylate catalysts, and kinetics of the reaction was studied. The reaction is a complex one, which proceeds summarily according to the following scheme : [chemical formula] The order and the rate constant of each reaction were determined (Table I). It was found that the rate constants, k_1,k_<-1>, k_2,k_<-2>, are affected by the concentration of catalysts (Table I, II, III), and that the activity of cupric chloride decreases during reaction (Fig.4,5). The rate of reaction of benzaldehyde, the rate of formation of benzylidenimine and benzonitrile were determined as the equations, (19), (20) and (10), respectively.
