Process for producing aromatic nitriles

摘要

The description relates to a process for producing aromatic nitriles from their corresponding aldehydes, in which the latter are caused to react with ammonia at temperatures of 200 to 500 DEG C in the gas phase in the presence of a catalyst based on molybdenum nitride of the general formula MoNxOy in which x = 0.25 to 1.0 and y = 0 to 1.0. It is thus possible to produce aromatic nitriles from the corresponding aldehydes with yields and selectivities of up to 98 % with conversions of up to 100 %.
