Abstract:	摘要： •The employed experimental apparatus is validated by measuring VLE of CO2+acetone.•VLE of binary CO2+pentanone (i.e. C5-ketones) mixtures are measured.•Binary VLE measurements are carried out at 313.15K, 333.15K, and 353.15K.•The Peng–Robinson equation of state is used to correlate the experimental data. 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 313.15K, 333.15K, and 353.15K up to a pressure of 11.8MPa 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 313.15K 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. 出版者： Elsevier B.V 出版日期： 2015-05-01 出處： The Journal of Supercritical Fluids, 2015-05, Vol.100, p.160-166 版權： 2015 Elsevier B.V. 識別號： ISSN: 0896-8446 識別號： EISSN: 1872-8162 識別號： DOI: 10.1016/j.supflu.2015.02.003
