| titleOfInvention | Process for producing purified naphthalenedicarboxylic acid |
| abstract | A step of obtaining a naphthalenedicarboxylic acid amine salt crystal by mixing a naphthalenedicarboxylic acid-containing raw material and an amine in a mixed solution of water and an organic solvent; and a purified naphthalenedicarboxylic acid from the crystal of the naphthalenedicarboxylic acid amine salt obtained in the above step A method for producing purified naphthalenedicarboxylic acid, comprising a step of obtaining an acid, wherein (1) an amine is added to a slurry containing water, an organic solvent and naphthalenedicarboxylic acid to form a naphthalenedicarboxylic acid amine salt. Is added to an aqueous solution prepared by dissolving naphthalene dicarboxylic acid amine salt in water, or the aqueous solution is solidified. By adding an amine to the liquid obtained by liquid separation, the metal component is insolubilized and precipitated. Precipitation is removed by solid-liquid separation of the metal component that provides a method for producing a purified naphthalenedicarboxylic acid. |
