ABSTRACT:
A method for producing an electrical insulating oil composition composed of benzyltoluene and ditolymethane. The composition is excellent in low-temperature characteristics 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.degree. to 550.degree. 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.
