The excess molar volumes, variations of the isentropic compressibility, the apparent molar volume, isentropic apparent molar compressibility, and thermal expansion coefficient were calculated from the experimental data. The excess molar volumes were negative throughout the whole composition range. Compressibility data in combination with low angle X-ray scattering and NMR measurements proved that the presence of micelles formed due to ion pair interaction above a critical concentration of the ionic liquid in the mixtures. The Peng–Robinson equation of state coupled with the Wong–Sandler mixing rule and COSMO–SAC model was used to predict densities and the calculated deviations were lower than 3%, for binary mixtures in all composition range.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-02-01T16:36:49Z No. of bitstreams: 1 plugin-download.php.pdf: 894112 bytes, checksum: 94854e9f65adb6adaf2ebcab4c0146df (MD5)Made available in DSpace on 2012-02-01T16:36:49Z (GMT).
