ABSTRACT:
An electrical insulating oil mainly comprising a fraction having excellent low temperature characteristics, said fraction being prepared by bringing a by-product oil fraction containing diphenylmethane and 1,1-diphenylethane into contact with alkylbenzenes in the presence of a ZSM-5 type synthetic zeolite catalyst, then recovering a fraction containing 1,1-diphenylethane and other diarylalkanes and containing mainly components having boiling points in the range of 270.degree. to 300.degree. C. as atomspheric pressure basis, said by-product oil fraction being by-produced in the preparation of ethylbenzene by alkylating benzene with ethylene.
