| titleOfInvention | Method for producing purified naphthalene dicarboxylic acid |
| abstract | Mixing a naphthalene dicarboxylic acid-containing raw material and an amine in a mixture of water and an organic solvent to obtain a crystal of a naphthalene dicarboxylic acid amine salt; And a process for obtaining purified naphthalene dicarboxylic acid from crystals of naphthalene dicarboxylic acid amine salt obtained in the above process, comprising: (1) a slurry comprising water, an organic solvent and naphthalene dicarboxylic acid; In the step of adding an amine to form a naphthalene dicarboxylic acid amine salt, the addition rate of the amine is 0.002 to 0.4 mol per minute per 1 mol of naphthalene dicarboxylic acid, or (2) naphthalene dicarboxylic acid amine salt in water Provided is a method for producing purified naphthalene dicarboxylic acid, in which a metal powder is insolubilized and precipitated by adding an amine to an aqueous solution prepared by dissolving or a solution obtained by solid-liquid separation of the aqueous solution, and the precipitated metal powder is removed by solid-liquid separation. do. |
