Ammoxidation of 2-furaldehyde by using oxygen gas as an oxidant was examined in methanolic solution at 30°, in the presence of cupric chloride and sodium methoxide catalysts, and the kinetics of the reaction was studied. The presence of furimido-methyl ester in addition to 2-furonitirile was confirmed as main oxidation products. The ratio of the yield of nitrile to imido ester depends on the concentration of sodium methoxide. It became clear from kinetic analysis that the overall reaction proceeds according to the following scheme : [numerical formula] The reaction order and the rate constant of each step were determined. It was found that k_1,k_2,and k_<-2> are affected by the concentration of catalysts, and that the activity of cupric chloride decreases during reaction. The rate of reaction of 2-furaldehyde and the rate of formation of furfurylidenimine, 2-furonitrile, and furimidomethyl ester were determined as the equations (23), (24), (6) and (12), respectively.
