Abstract
The present invention relates to a method for achieving high purity separation and refinement by controlling morphology and particle size of 2,6-dimethylnaphthalene. And more particularly, the present invention relates to a method for obtaining high purity 2,6-dimethylnaphthalene crystals, in which crystallization is carried out with a solvent that enables the crystals to form a square-platy shape. During the process, crystallization variables such as, stirring speed, cooling speed, solvent and composition ratio, are adjusted to control morphology and particle size of 2,6-dimethylnaphthalene and to remove aggregation, thereby obtaining 2,6-dimethylnaphthalene crystals of high purity.
