Abstract

See full text

In a process for producing biphenyl compounds, a Cn aromatic hydrocarbon may be hydroalkylated to give C2n cycloalkylaromatic compounds and byproduct Cn saturated cyclic hydrocarbons. The C2n cycloalkylaromatic compounds are dehydrogenated to provide the biphenyl compounds. The Cn saturated cyclic hydrocarbons may also be dehydrogenated back to the corresponding Cn aromatic hydrocarbon, which may be recycled to provide additional feed. Although both the intermediate C2n cycloalkylaromatic compounds and the byproduct Cn saturated cyclic hydrocarbons should be dehydrogenated, at least part of the dehydrogenation of the Cn saturated cyclic hydrocarbons should take place in the absence of C2n or greater hydrocarbons. Thus, dehydrogenation of the byproduct Cn saturated cyclic hydrocarbons should take place at least in part separately from dehydrogenation of the C2n cycloalkylaromatic compounds.
