| titleOfInvention | Method for purifying 2,6-naphthalenedicarboxylic acid |
| abstract | The present invention relates to a method for purifying 2,6-naphthalenedicarboxylic acid, and in particular, protic polarity selected from the group consisting of crude 2,6-naphthalenedicarboxylic acid in the form of an amine salt, alcohol, water, and mixtures thereof. The present invention relates to a method for purifying 2,6-naphthalenedicarboxylic acid including a step of recrystallization using a solvent and a solvent containing acetate. According to the present invention, 2,6-naphthalenedicarboxylic acid excellent in purity and hue can be obtained, and at the same time, acetate, which is a by-product of a pure oxidation process, is used as a solvent, economically and environmentally friendly. Can be obtained. |
