The main conclusion
Three expressions were developed to determine the thermodynamic equilibrium constants for xylene isomerization in the liquid phase between 250 and 550 K. A simple procedure was followed based on published thermodynamic functions at saturation pressure.
Personal evaluation of the paper with future thinking
there are very few references of thermodynamic equilibrium for xylene isomerization in the liquid phase in the literature. For instance, Cappellazzo et al.and Norman. et al. carried out experiments on xylene isomerization in the liquid phase; they used the equilibrium constants within the kinetic parameters; however, they did not show the actual values.
