Isothermal vapor-liquid equilibria data and mixture critical points data for the n-pentane + 1-propanol, 1-butanol, 2-butanol systems were measured. A circulation type equipment with the view cell was used and the critical pressures were determined from the critical opalescence of the mixtures. These mixtures show non-ideal behavior because of the hydrogen bond of alkanol. The measured data were correlated with the Peng-Robinson-Stryjek-Vera (PRSV) equation of state with Wong-Sandler mixing rule and Multi-Fluid Nonrandom Lattice Fluid with Hydrogen Bonding(MF-NLF-HB) equation of state.
