Page/Page column 6-7, (2008/06/13)
[PROBLEMS] To provide a process for industrially stably producing a highly purified 2,7-dimethylnaphthalene with high yield from a dimethylnaphthalene isomer mixture at low production cost through convenient means. [MEANS FOR SOLVING PROBLEMS] There is provided a method of purifying 2,7-dimethylnaphthalene, characterized by including the step of bringing a raw oil containing a mixture of 1,7-dimethylnaphthalene and 2,7-dimethylnaphthalene together with a developing solvent into contact with L-type zeolite to thereby effect adsorption of 1,7-dimethylnaphthalene.
