The density and surface tension of these ionic liquids were measured from (293.15 to 343.15) K. Their values decreased with increasing temperature. The physical properties such as coefficient of thermal expansion, molecular volume, standard molar entropy, lattice energy, and molar enthalpy of vaporization were estimated using experimental data. The critical temperature of the ionic liquids was estimated using Eötvos equations. The values were then used to estimate the boiling temperature of the ionic liquids according to methods of Rebelo. The interstice model was used to predict the thermal expansion coefficient of the ionic liquids, α, and the result was in very good agreement with the experimental value. In addition, the parachor method was used to predict the physical properties of the ionic liquids H 2N-C nmimPF 6 (n = 4, 5, 6). © 2012 American Chemical Society. date: 2012 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84868681863&doi=10.1021%2fje300288a&partnerID=40&md5=1c63751a71512fbf008fd1e4f726e366 id_number: 10.1021/je300288a full_text_status: none publication: Journal of Chemical and Engineering Data volume: 57 number: 11 pagerange: 2923-2927 refereed: TRUE issn: 00219568 citation: Kurnia, K.A. and Mutalib, M.I.A. and Man, Z. and Bustam, M.A. (2012) Density and surface tension of ionic liquids H 2N-C 2mimPF 6 and H 2N-C 3mimPF 6.
