摘要： A process for producing a cyanopyridine which comprises reacting the corresponding methylpyridine, ammonia and an oxygen-containing gas in the presence of a catalyst comprising a vanadium oxide, a chromium oxide, a boron oxide and optionally a phosphorus oxide and/or molybdenum oxide held on silica is disclosed. According to the present invention, the reactivity of the raw material and the yield of the reaction product are high.
