The present invention relates to methods for preparing aromatic nitriles and, more specifically, to a method for preparing phthalonitriles. The present method for preparing phthalonitriles resides in subjecting xylene to oxidative ammonolysis at a temperature of 340.degree. to 480.degree. C. in the presence of a catalyst having the following composition (in weight percent):

Method for preparing phthalonitriles

According to the invention, a method of producing orthoaminobenzonitrile is provided according to which ortho-toluidine is reacted with ammonia at a temperature of 360.degree.-460.degree. C. in the presence of oxygen, or a mixture thereof with inert gases, and a catalyst, namely, a mixture of oxides of antimony, bismuth, vanadium, and phosphorus taken in a weight ratio 5-12:3-9:1-9:0.5-4, respectively, the catalyst being applied to a support. The invention ensures an increase in the yield of orthoaminobenzonitrile per unit volume of the catalyst and selectivity with respect to the final product.
