ABSTRACT OF THE DISCLOSURE A method for producing an electrical insulating oil composition composed of benzyltoluene and ditolymethane. The composition is excellent in low-temperature character- istics and contains substantially no chlorine. The method comprises the steps of reacting monocyclic aromatic hydrocarbon with diarylmethane which has been prepared without using a chlorinated hydrocarbon as a starting material, at a temperature of -10 to 550°C in the presence of a disperoportionation catalyst to prepare a reaction product containing benzyltoluene and ditolylmethane, and recovering benzyltoluene and ditolylmethane from said reaction product by distillation.
