PURPOSE:To produce 1-phenyl-1-naphthylethane having excellent low-temperature fluidity in high efficiency, by reacting naphthalene with styrene using clay as a catalyst at a specific molar ratio of charged raw materials and a specific reaction temperature. CONSTITUTION:1-Phenyl-1-naphthylethane is produced by reacting naphthalene with styrene selecting the charged molar ratio of naphthalene/styrene to 1-10 (especially the styrene concentration in the reaction system is preferably <=10%) in the presence of clay (especially preferably bentonite, montmorillonite, acid clay or kaolin) at 20-230 deg.C (especially preferably 80-150 deg.C). The reaction product contains 30-60mol% titled compound. USE:Intermediate raw material for traction drive fluid and raw material for plasticizer for rubber and various synthetic resins, a solvent for pressure- sensitive copying paper, etc.
