摘要: The present invention relates to a method and an apparatus for continuously separating aromatic dialdehyde from a reaction mixture obtained by gas-phase oxidation of dimethylbenzene. The method for continuously separating aromatic dialdehyde includes the steps of congealing aromatic dialdehyde by cooling the gas-phase reaction mixture including the aromatic dialdehyde, which is obtained by gas-phase oxidation of dimethylbenzene, to 5-70° C. and separating the congealed aromatic dialdehyde from the remaining reaction mixture. Using the method and apparatus in accordance with the present invention, aromatic dialdehyde can be effectively and selectively separated from a reaction mixture obtained by gas-phase oxidation of dimethylbenzene in high yield.
