N2 - A new experimental apparatus for performing simultaneous determination of high-pressure vapor-liquid equilibria (VLE) and saturated densities was developed in this work. The experimental methodology was verified by measuring these properties for the carbon dioxide. +. 1-propanol and carbon dioxide. +. 2-propanol systems from 313 to 363. K. The apparatus is based on the static-analytic method for VLE determinations and was slightly modified by coupling a vibrating U-tube densitometer to obtain saturated densities for both vapor and liquid phases. VLE measurements agreed with previous literature data and were correlated with the Peng-Robinson equation of state coupled to the Wong-Sandler mixing rules. Saturation densities at temperatures above 313. K have not been published up to now.
