Using an aromatic compound having a solid cyano group at room temperature as a raw material, melting and transporting the compound by transport and melting means, evaporating the compound, mixing the compound and halogen gas, In the method for producing a nucleohalogenated aromatic compound through each step of reacting the compound vapor and halogen gas in the gas phase in the presence of a catalyst, the magnetic of the aromatic compound containing a cyano group in the compound vapor reacted with halogen gas The average pore radius of the method for producing a nucleohalogenated aromatic compound having a cyano group and the catalyst to be used by nitrogen adsorption of activated carbon, wherein the content of the condensate is maintained at 2.5 mol% or less relative to the compound, is 12.2 占 폚 or higher. And the water vapor adsorption method in the pore radius of activated carbon of 5 to 100 It is obtained to the cumulative pore volume of not less than 0.4g / cc. |
