Abstract
In a process for producing a methyl-substituted biphenyl compound, at least one methyl-substituted cyclohexylbenzene compound of the formula: wherein each of m and n is independently 1, 2, or 3, is contacted with hydrogen in the presence of a hydrogenation catalyst to produce a hydrogenation reaction product comprising at least one methyl-substituted bicyclohexane compound, and the methyl-substituted bicyclohexane compound is then contacted with a dehydrogenation catalyst to produce a dehydrogenation reaction product comprising at least one methyl-substituted biphenyl compound.
