The Equilibrium Constant for the Methylcyclohexane–Toluene System

The equilibrium constant for the methylcyclohexane–toluene system has been experimentally determined due to a lack of fit appearing in kinetic evaluations when using literature values for the equilibrium constant. The most recent literature value of Keq(T=650 K)=4.61±0.04×109 kPa3 due to J. Akyurtlu and W. E. Stewart (J. Catal.51, 101 (1978)) was redetermined to a value of Keq(T=650 K)=3.60±0.05×109 kPa3 with isothermal experiments using methylcyclohexane and toluene feeds separately.
