A novel heating medium comprising 1,1-diphenyl ethane is provided for use in heating processes. Said heating medium has good thermal stability, a high boiling point and a low melting point. It is applicable over a wide range of temperatures and easily degradable by microorganisms. The oily substances, by-produced in the step of separating ethyl benzene from polyalkyl benzenes in production of ethyl benzene from the reaction between benzene and ethylene, may be available for preparation of said heating medium.
