PC-SAFT model and experimental explicating interaction of binary and ternary systems of 2-ethoxyethanol, methylcyclohexane and N-methylcyclohexylamine

In this project upon measurements of density rho, speed of sound u, and refractive index nD, the excess molar volumes VEm, deviations in isentropic compressibility Delta Ks, and in refractive index Delta nD, were calculated for the whole range of composition and temperatures of T = (298.15-308.15-318.15)K for binary and ternary systems of 2-ethoxyethanol, methylcyclohexane, and N-methylcyclohexylamine. Results correlated with the Redlich-Kister and Cibulka equations. The Perturbed-Chain Statistical Associating Fluid Theory (PC-SAFT) equation of state was used to predict density and there was a good agreement between calculated and experimental density. Inter-molecular interactions between like and unlike molecules were discussed for the systems. It seems that study provides useful insights into the properties and behavior of these mixtures, which could have potential appli-cations in various fields such as chemistry and materials science.
