High-Pressure Vapor-Liquid Equilibria,Liquid Densities,and Excess Molar Volumes for the Carbon Dioxide+2-Propanol System from(308.10 to 348.00)K

摘要

Vapor-liquid equilibrium data and volumetric properties(density and excess molar volumes)of the carbon dioxide(1)+2-propanol(2)system have been determined for seven molar compositions,z1,close to 0.15,0.20,0.42,0.60,0.80,0.95,and 0.97,using a vibrating tube densimeter,which takes advantage of a forced path mechanical calibration model.The Peng-Robinson equation of state including Panagiotopoulos and Reid mixing rules is used to correlate the data.Comparison of the new data with selected literature data and correlated results shows good consistency agreement,demonstrating the reliability of the data presented herein.
