| titleOfInvention | Method for producing 2,6-naphthalenedicarboxylic acid |
| abstract | (57) [Abstract] [Purpose] 2,6-naphthalenedicarboxylic acid without the use of large amounts of metal catalyst, without causing the precipitation of alkali metal salts of 2,6-naphthalenedicarboxylic acid Efficiently produce 2,6-naphthalenedicarboxylic acid by oxidation of diisopropylnaphthalene. [Structure] 2,6-diisopropylnaphthalene or its oxidized intermediate was used in an aliphatic carboxylic acid solvent with a catalyst consisting of a cobalt compound, a manganese compound and a bromine compound in the presence of amides at a temperature of around 200 ° C. Oxidized with gaseous oxygen to produce 2,6-naphthalenedicarboxylic acid. The reaction product is cooled to room temperature, and the precipitated solid is separated and washed to ensure purity. 97% or more of 2,6-naphthalenedicarboxylic acid is obtained. |
