| titleOfInvention | Method for producing 2,6-naphthalenedicarboxylic acid |
| abstract | [Problem] To produce 2,6-naphthalenedicarboxylic acid by liquid phase oxidation using 2,6-dialkylnaphthalene as a raw material, Even if the recycling rate of the reaction mother liquor is increased, a sufficient crystal separation ability is obtained, and a continuous production method with excellent production efficiency is provided. Kind Code: A1 A 2,6-dialkylnaphthalene is oxidized using a molecular oxygen gas in a solvent containing a lower aliphatic carboxylic acid in the presence of a catalyst comprising a heavy metal compound and a bromine compound. In the continuous production of 2,6-naphthalenedicarboxylic acid, after heating the mother liquor separated from the oxidation reaction product slurry through the solid-liquid separation step at a temperature of 150 ° C. or higher, Circulate to the oxidation reaction step. |
