摘要

Vapor-liquid equilibrium (VLE) data of the binary mixtures carbon dioxide (CO2) + acetone and CO2 + pentanones (i.e. all C5-ketones, which are 3-methyl-2-butanone, 2-pentanone, and 3-pentanone) are measured at 313.15 K, 333.15 K, and 353.15 K up to a pressure of 11.8 MPa using a high pressure view cell technique based on the synthetic method. The VLE measurement results of CO2 + acetone are compared to the available experimental data from the literature in order to validate the employed experimental apparatus. In case of binary CO2 + pentanone mixtures, only for CO2 + 3-methyl-2-butanone and CO2 + 2-pentanone at 313.15 K experimental data are available in the literature. The present measurements thus complete the literature database for binary VLE of CO2 + pentanones. All present data are compared to the results from the Peng-Robinson equation of state (PR EOS) with the van der Waals one-fluid mixing rule and from the combination of the PR EOS with the UNIQUAC model through the Huron-Vidal mixing rule.
