(57) [Abstract] [Purpose] To provide a method for industrially advantageously producing a corresponding cyanonaphthalene at a high conversion and a high selectivity by ammoxidating methylnaphthalenes in the presence of a catalyst. is there. [Composition] When a raw material mixed gas comprising methylnaphthalene, ammonia and a molecular oxygen-containing gas is catalytically reacted on a catalyst to produce a cyanonaphthalene, the catalyst used is vanadium as an active component, an alkali metal and / or Or alkaline earth metal, antimony, nickel, It is characterized by containing at least one element selected from the group consisting of chromium, molybdenum, cobalt, manganese, tin, phosphorus and bismuth and containing titanium oxide and / or zirconium oxide as a carrier component. |
