spelling Alvarez, Víctor H.Silva, Silvana Mattedi eAznar, MartinAlvarez, Víctor H.Silva, Silvana Mattedi eAznar, Martin2012-02-08T17:07:44Z20110021-9614http://www.repositorio.ufba.br/ri/handle/ri/5337v. 43, n. 6.Acesso restrito: Texto completo. p. 895-900.This paper reports the density, refraction index, and (vapor + liquid) equilibria (VLE) for binary systems {aldehyde + 1-ethyl-3-methylimidazolium ethylsulfate ([emim][EtSO4])}: {propionaldehyde + [emim]- [EtSO4]} and {valeraldehyde + [emim][EtSO4]}. The uncertainties for the temperature, pressure, and compositions measurements for the phase equilibria are ±0.1 K, ±0.01 kPa and ±0.0004, respectively. A qualitative analysis of the variation of the properties with changes in solvent and temperature was per- formed. The Peng–Robinson equation of state (PR EoS), coupled with the Wong–Sandler mixing rule (WS), is used to describe the experimental data. To calculate activity coefficients we used three different models: NRTL, UNIQUAC, and COSMO-SAC. Since the predictive liquid activity coefficient model COSMO-SAC is used in the Wong–Sandler mixing rule, the resulting thermodynamic model is a completely predictive one. The prediction results for the density and for the (vapor + liquid) equilibria have a deviation lower than 2.3% and 1.6%, respectively. The (vapor + liquid) equilibria predictions show a good description for the propionaldehyde system and only a qualitative description for the valeraldehyde system.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-02-08T17:07:44Z No. of bitstreams: 1 __pdn.sciencedirect.com_....0-S0021961411000279-main.pdf: 261195 bytes, checksum: 586a9021a62ca8c0e413153746b5a003 (MD5)Made available in DSpace on 2012-02-08T17:07:44Z (GMT).
