ABSTRACT:
A (methyl-substituted)diphenyl methane such as methyldiphenylmethane is prepared by a coupling reaction wherein a methyl-substituted benzene such as toluene is contacted with a solid heterogeneous catalyst having labile oxygen such as an oxide of vanadium, rhenium or molybdenum. By-product formation, especially the formation of carbon dioxide, is significantly reduced by the practice of this process.
