Contributions of enthalpy and entropy factors to isomerization equilibrium of isopropyl- and cyclohexylbenzenes
Experimental and theoretical data on the liquid-phase equilibrium of the positional isomerization of isopropyl- and cyclohexylbenzenes are analyzed in detail. Contributions of the enthalpy and entropy factors to the equilibrium constants of the ortho-meta and para-meta transformations are estimated.

Liquid-Phase Catalytic Oxidation of 2,4-Dimethylbiphenyl
2,4-Dimethylbiphenyl synthesized by alkylalion of m-xylene with cyclohexanol and subsequent dehydrogenation was oxidized catalytically in the liquid phase to 2,4-biphenyldicarboxylic acid. The effects of temperature, the catalyst, and initial concentrations of reactants on the rate and efficiency of the process were studied.
