PURPOSE:To provide a method for producing a phenoxy-substituted benzonitrile in high space time yield. CONSTITUTION:In producing a phenoxy-substituted benzonitrile of formula II by subjecting a phenoxy-substituted toluene of formula I to vapor-phase contact reaction with ammonia and molecular oxygen in the presence of a catalyst, an oxide expressed by the formula VaSbbCrcTidAeOx [A is at least one or more kinds of elements selected from a group consisting of alkali metals, alkaline earth metals, boron and phosphorus; when (a) is 1, (b) is 0.5-10, (c) is 0.1-10, (d) is 0-50, (e) is 0-5 and (x) is an arbitrary value determined from a valency of oxygen atom, valencies of other elements and an atomic ratio] is used as the catalyst and a molar ratio of the molecular oxygen/the phenoxy- substituted toluene is set to 1.5-7 to produce the objective phenoxy-substituted benzonitrile in high space time yield. |
