PURPOSE: To produce the subject substance in high efficiency and selectivity by reacting ethylnaphthalene at a temperature within a specific range in the presence of a composite metal oxide catalyst exhibiting a powder X-ray diffraction pattern same as that of mordenite.
CONSTITUTION: The subject substance can be produced by reacting ethylnaphthalene (preferably having a basic nitrogen content of ≤20ppm) at 100-400°C (preferably 150-300°C) in the presence of a composite metal oxide catalyst exhibiting a powder X-ray diffraction pattern same as that of mordenite. The catalyst is e.g. mordenite or chemically treated mordenite subjected to ion-exchange treatment, fluorination treatment, dealuminizing treatment, etc. The catalyst may be silica-zirconia, titania-zirconia, etc., exhibiting a powder X-ray diffraction pattern same as that of mordenite. The di- or triethylnaphthalene contained in the reaction mixture is preferably returned to the reactor after trans-ethylation reaction.
