  • Patent number: 6756509
    Abstract: A method for purifying crude 2,6-naphthalenedicarboxylic acid includes a reduction step of reducing crude 2,6-naphthalenedicarboxylic acid containing 6-formyl-2-naphthoic acid with hydrogen and a cleaning step of cleaning the reduction product with alcohol. Preferably, in the reduction step, the crude 2,6-naphthalenedicarboxylic acid and the hydrogen is brought into contact with a hydrogenation catalyst in a liquid phase, and particularly in water. The method makes the purification process less complex and makes it possible to produce high-purity 2,6-naphthalenedicarboxylic acid without damaging equipment or increasing cost.
