Abstract: Sets of isothermal vapour-liquid equilibrium data are presented for the system toluene-N-methylpyrrolidone at 40°C, 50°C, and 60°C, measured by a static method. The binary parameters of equations for the concentration dependence of the excess Gibbs energy (NRTL, Wilson, van Laar equations, and the Redlich-Kister 4th-order expansion) were evaluated using a simple objective function based on the maximum likelihood method.
