Dyson, Paul J. Laurenczy, Gábor <jats:p>The viscosities of the ionic liquids [bmim][PF<jats:sub>6</jats:sub>] and [bmim][TF<jats:sub>2</jats:sub>N] (bmim = 1-methyl-3- butylimidazolium, TF<jats:sub>2</jats:sub>N = bis(trifluoromethylsulfonyl)imide) have been determined under CO<jats:sub>2</jats:sub> pressure at 298 K. The viscosity decreases from 381 to 23 cP for [bmim][PF<jats:sub>6</jats:sub>] without CO<jats:sub>2</jats:sub> and for 2.17 molal CO<jats:sub>2</jats:sub> solutions (mole fraction X<jats:sub>CO</jats:sub>₂ = 0.381, 55 bar CO<jats:sub>2</jats:sub>), respectively. For [bmim][TF<jats:sub>2</jats:sub>N] the viscosity decreases from 54 cP for the ionic liquid to 21 cP for a 1.61 molal solution of CO<jats:sub>2</jats:sub> (mole fraction X<jats:sub>CO</jats:sub>₂ = 0.403, 55 bar CO<jats:sub>2</jats:sub>).</jats:p> application/pdf https://sonar.ch/global/documents/211323 eng info:eu-repo/semantics/altIdentifier/doi/10.1515/znb-2008-0614 info:eu-repo/semantics/altIdentifier/issn/1865-7117 info:eu-repo/semantics/openAccess Zeitschrift für Naturforschung B. - Walter de Gruyter GmbH. - 2008, vol. 63, no. 6, p. 681-684 General Chemistry Determination of the Viscosity of the Ionic Liquids [bmim][PF6] and [bmim][TF2N] Under High CO2 Gas Pressure Using Sapphire NMR Tubes http://purl.org/coar/resource_type/c_6501
