N2 - The critical temperatures (Tc) and critical pressures (pc) of five binary mixtures of n-butanol + n-alkane (C = 6, 7, 8, 9, 10) as well as two ternary mixtures (n-butanol + hexane + heptane and n-butanol + heptane + octane) were measured over the whole concentration range using a flow method apparatus. The Tc of binary mixtures which contain heptane, octane, and nonane display a significant nonideality. The pc of binary mixtures increase with the increasing mole fraction of n-butanol and pc-x1 curves rise up more obviously in richer n-butanol regions. The trends of the Tc-w1 curves of two ternary mixtures slightly change with the increasing mass fraction of corresponding n-alkane components in mixtures. By using the Redlich-Kister equations, average absolute deviations (AADs) of binary mixtures were less than 0.09% and 0.31% for Tc and pc, respectively. Tc and pc of ternary mixtures were correlated using Cibulka's equations and Singh-Sharma's equations.
