Vapor-liquid equilibria for the aniline/naphthalene, toluene/aniline, and naphthalene/quinoline systems have been determined at 0-1500 kPa and 490-623 K by using a static equilibrium cell. The data can be accurately correlated with the modified Peng-Robinson equation of state by using density-dependent mixing rules. The binary interaction parameters and correction factors for the equation of state are reported at each isotherm. The presence of coal-derived solids in these binary systems did not influence any of the binary bubble pressures.
