Vapor pressures of six normal alkanes (heneicosane, tricosane, pentacosane, heptacosane, nonacosane, and triacontane) were measured from 0.5 Pa to 600 Pa using a static apparatus. The experimental data (P-T) were smoothed using the Antoine equation and compared with the available literature values. Pressures were then calculated by means of a modified Peng-Robinson equation of state and compared with experimental values. The model represents the experimental results quite well.
