A method for preparing an aromatic dialdehyde and a manufacturing system for the same |
| abstract |
The present invention relates to a method for preparing an aromatic dialdehyde, comprising, a) a step of gas phase oxidation reaction for preparing aromatic dialdehyde from dimethyl benzene; b) a step of separation for selectively recovering crude aromatic dialdehyde of molten phase from the reaction product of the step (a); and c) a step of purification for obtaining highly pure aromatic dialdehyde by purifying said crude aromatic dialdehyde, and a manufacturing system used for the preparation method. The method for preparation of the aromatic dialdehyde according to the present invention is simple, effective, and advantageous in that highly pure aromatic dialdehyde can be continuously prepared. |
