N2 - A static-analytical apparatus with visual sapphire windows and pneumatic capillary samplers has been used to obtain new vapor-liquid equilibrium data for the N 2 + C 10H 22 system over a wide temperature range from (344 to 563) K and at pressures up to 50 MPa. Equilibrium phase compositions and vapor-liquid equilibrium ratios are reported. The experimental data were modeled with the PR (Peng-Robinson) and PC-SAFT (perturbed-chain statistical association fluid theory) equations of state by using one-fluid mixing rules and a single temperature-independent interaction parameter. Results from the modeling effort showed that the PC-SAFT equation was superior to the PR equation in correlating the experimental data of the N 2 + C 10H 22 system over the whole temperature, pressure, and composition range studied.
