Vapor-Liquid Equilibria for Three Binary Mixtures of CO2 with Esters at Elevated Pressures
碩士 === 國立臺灣大學 === 化學工程學研究所 === 87 === A semi-flow type apparatus was used to measured the vapor-liquid equilibrium (VLE) data of CO2 + ethyl benzoate, CO2 + diethyl succinate and CO2 + isoamyl acetate binary mixtures at temperatures 308.15 K, 318.15 K and 328.15 K over the pressure range...

| Summary: | 碩士 === 國立臺灣大學 === 化學工程學研究所 === 87 === A semi-flow type apparatus was used to measured the vapor-liquid equilibrium (VLE) data of CO2 + ethyl benzoate, CO2 + diethyl succinate and CO2 + isoamyl acetate binary mixtures at temperatures 308.15 K, 318.15 K and 328.15 K over the pressure range from 1 MPa to 12 MPa. Total 82 new data were obtained for these three binary mixtures.
The KI equation was used to correlate the solubility of CO2 in esters and the Henry's constants were obtained. The Henry's constants increase with the increasing temperature.
Equation of state method was used to correlate the new vapor-liquid equilibrium data. It shows that the Soave equation of state with the two-parameter van der Waals one-fluid mixing rule yields the best results.
