| titleOfInvention | Method for producing 2,6-dimethylnaphthalene |
| abstract | The present invention comprises the steps of cold crystallizing a dimethylnaphthalene-containing mixture containing 2,6-dimethylnaphthalene; Solid-liquid separation; And it comprises a step of washing the solid component with a solvent, and the solid-liquid separation step relates to a method for producing high purity 2,6-dimethylnaphthalene, characterized in that it comprises compression filtration. In the method of the present invention, the pressure at the time of compression filtration is preferably 10 kg / cm 2 or more. According to the method of the present invention, high purity 2,6-dimethylnaphthalene can be prepared even when using DMN mixture containing 5% by weight or more of 2,7-dimethylnaphthalene as a starting material. A high purity 2,6-dimethylnaphthalene can be prepared from the DMN mixture containing 25% by weight or less as a starting material. |
