ABSTRACT:
Aromatic hydrocarbons are converted to biaryl compounds in a two-step process comprising hydroalkylation of the aromatic hydrocarbons to cycloalkyl aromatic hydrocarbons followed by dehydrogenation in the presence of a metal dehydrogenation catalyst and an acidic support to convert the cycloalkyl aromatic hydrocarbons to biaryl compounds. In one embodiment, benzene is hydroalkylated to cyclohexylbenzene, and the cyclohexylbenzene then dehydrogenated to biphenyl.
