Method of producing ortho-aminobenzonitrile

摘要

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 DEG -460 DEG 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.
