摘要
New experimental results are presented for the total pressure above liquid mixtures of carbon dioxide and the ionic liquid 1-hexyl-3-methylimidazolium, bis(trifluoromethylsulfonyl)imide ([hmim][Tf2N]). The series of experiments were performed at preset temperature and liquid phase composition by means of a very precise high-pressure view-cell technique based on the synthetic method. A temperature range from (293.15 to 413.2) K was investigated where the maximum pressure reached approximately 10 MPa. Gas molalities in [hmim][Tf2N] ranged up to about 4.7 mol center dot kg(-1). The (extended) Henry's law is successfully applied to correlate the solubility pressures. (c) 2006 Elsevier Ltd. All rights reserved.
