摘要：
Vapor-liquid equilibria (VLE) and critical point for the (n-pentane + 1-propanol) and (n-pentane + 2-methyl-1-propanol) at temperature of (468.15, 483.15, 498.15, and 513.15) K were measured with a circulation-type apparatus with a visual method. Critical points were identified by critical opalescence and compared with the published results for (n-pentane + alkanols). The results were correlated with the Peng-Robinson-Stryjek-Vera (PRSV) equation of state with Wong-Sandler mixing rule. This model correlates the experimental data with a good accuracy.
