N2 - Experimental vapor-liquid equilibria for the systems carbon dioxide. +. 1-butanol and carbon dioxide. +. 2-butanol were obtained from 313 to 363. K via a static-analytic set-up. A vibrating U-tube densitometer was coupled to this apparatus to perform simultaneous measurements of both saturated densities of the vapor and liquid phases. The suitability of this apparatus was checked by comparing the experimental vapor-liquid equilibrium and saturated density results with the literature data. The experimental vapor-liquid equilibrium data were correlated using the Peng-Robinson equation of state coupled to the Wong-Sandler mixing rules with good agreement; however densities using the same model were not satisfactorily represented.
