Your Mendeley pairing has expired. In this work, a conductor-like screening model for realistic solvation was used to predict the activity coeffs. using Clausius-Clapeyron equation. In addn., the enthalpies of soln. data of a series of important gases such as CO2, SO2, CO, N2, O2, and H2 are exhaustively collected over a wide temp. Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. Henry’s law constants are determined from that solubility pressure data within an uncertainty of about ±1.5%. use. of carbon dioxide in room temp. New experimental results for the solubility of carbon dioxide in the ionic liquid [hmim][Tf 2 N] are presented for temperatures from about (293 to 413) K and pressures up to about 10 MPa. (ILs) based sepns. Among various dialkylimidazolium dialkylphosphates tested, 1-ethyl-3-methylimidazolium diethylphosphate ([EMIM][Et2PO4]) and 1-butyl-3-methylimidazolium dibutylphosphate ([BMIM][Bu2PO4]) exhibited the comparable or better capability of dissolving CO2 in comparison with that of [BMIM][BF4], but their absorption capacities were still lower than that of 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([BMIM][Tf2N]). equipped with a variable-vol. data of mixed gases in ILs are also scarce, which can provide fundamental knowledge for developing the actual processes because one gas soly. chem. This property is paramount for assisting in the development and testing of accurate mol. Find more information about Crossref citation counts. Henry's Law consts. The chemical symbol remains the same as gaseous carbon dioxide (CO₂). Han Miao, Ina Stephan, Thomas Dimke, Vincenzo Alessandro Cataldo, Markus Antonietti.
