FIELD: chemistry.
SUBSTANCE: present invention relates to a catalyst, a method for producing a catalyst and a method for producing acrylonitrile. A catalyst for the oxidative ammonolysis reaction to produce acrylonitrile and hydrogen cyanide is described, containing Mo, Bi and Fe and satisfying the following ratios during X-ray phase analysis: 0.10 < P/R < 0.18 and 0.06 < Q/R < 0.30, where P denotes the peak intensity at 2θ = 22.9±0.2°, Q denotes the intensity peak at 2θ = 28.1 ± 0.1°, and R denotes the intensity of the peak at 2θ = 26.6 ± 0.2°.
EFFECT: catalyst used in the method for producing acrylonitrile and hydrogen cyanide, including the stage of oxidative ammonolysis of propylene, can increase the yield of hydrogen cyanide, while preventing a decrease in the yield of acrylonitrile.
