Method and apparatus for the purification of high-purity 2,6-naphthalene dicarboxylic acid |
| abstract |
Disclosed is a method for purifying 2,6-naphthalenedicarboxylic acid (NDA) that is present in a solid state in a solution. According to the method, sintered metal membrane filtration units are used to efficiently separate and purify 2,6-naphthalenedicarboxylic acid separated after hydrogenation and crystallization in a continuous process. An apparatus for implementing the method is further provided. |
