titleOfInvention | Method for producing 2,6-dimethylnaphthalene and method for producing 2,6-naphthalenedicarboxylic acid |
abstract | Industrially advantageous method for efficiently producing high purity 2,6-dimethylnaphthalene in high yield by crystallization of dimethylnaphthalene isomer mixture and 2,6- in 2,6-dimethylnaphthalene obtained by this method A method for preparing naphthalenecarboxylic acid is disclosed.n n n The first invention is a method for producing high purity 2,6-dimethylnaphthalene by crystallizing 2,6-dimethylnaphthalene in a dimethylnaphthalene isomer mixture under the presence of a solvent,n n n In the second invention, when the crystal of 2,6-dimethylnaphthalene precipitated by the crystallization is filtered by a filtration device, the filter cake is peeled from the filter cloth, and then the filter cloth is washed with a solvent having a temperature higher than the filtration temperature. It is a method of stably producing 2,6-dimethylnaphthalene,n n n The third invention provides a method for producing high purity 2,6-naphthalenedicarboxylic acid by liquid-phase oxidation of 2,6-dimethylnaphthalene obtained by these methods. |
