Vapor-liquid (VLE) and vapor-liquid-liquid equilibria (VLLE) data for the carbon dioxide + pentan-1-ol (n-pentanol) system at (293.15, 303.15, 316.65, and 333.15) K up to 10.67 MPa are reported. The experimental method used in this work was a static analytical method with liquid and vapor phase sampling. The new experimental results are discussed and compared with available literature data. Measured data and literature data for the carbon dioxide + n-pentanol system were modeled with the Soave-Redlich-Kwong (SRK) and Peng-Robinson (PR) equation of state (EoS) using classical van der Waals (two-parameter conventional mixing rule, 2PCMR) mixing rules. A single set of interaction parameters was used to predict the complex phase behavior of the binary mixture carbon dioxide + n-pentanol. Both models predict correctly the phase behavior and a good account of the majority of the data available in the literature.
