Title:
芳香族ハロゲン化物の製造方法及び製造設備
Document Type and Number:
Japanese Patent JP7401998
Kind Code:
B2
Abstract:
To provide a method and an apparatus for producing an aromatic halide, which can remove a metal component contained in a catalyst from a distillation residue liquid of an aromatic halide and can improve a recovery rate of a halide.SOLUTION: There is provided a method for producing an aromatic halide including the steps of: (a) producing an aromatic halide from an aromatic compound and at least one of an inorganic halide and a halogen using a metal-containing catalyst; (b) mixing a distillation residue liquid after distilling the aromatic halide, and an extractant separating the distillation residue liquid to obtain a mixed liquid and then extracting a metal compound derived from the metal-containing catalyst contained in the distillation residue liquid to the extraction agent side to obtain an extraction residue liquid; (c) burning the extraction residue liquid in a combustion furnace to generate an exhaust gas containing halides; and (d) recovering the halides from the exhaust gas.SELECTED DRAWING: Figure 1
