<p>(Methyl-substituted) diphenyl methanes are prepared by coupling at least a methyl-substituted benzene and optionally benzene into the (methyl-substituted) diphenyl methane by contacting at least the methyl-substituted benzene with a solid heterogeneous reactant-catalyst having labile oxygen under conditions whereby the (methyl-substituted) diphenyl methane is prepared. The solid heterogeneous reactant-catalyst having labile oxygen is selected from a vanadium oxide, a molybdenum oxide, a rhenium oxide, a tungsten oxide and other oxide catalysts. By-product formation, especially formation of carbon dioxide, can be very low.</p> |
