Densities, speeds of sound and viscosities of pure and the binary mixtures of [BMIM][CF 3 SO 3 ] ? ethyl acetate or 1-butanol have been measured over the entire range of mole fractions at T = (298.15-323.15) K and at 0.1 MPa pressure using an Anton Paar density and sound velocity meter DSA 5000M and a Lovis microviscometer 2000M. The excess molar volumes (V E ), viscosity deviations (Dg) and the isentropic compressibility deviations (Dj S ) have been calculated using the experimental data. The variations in V E , Dg and Dj S with changes in mole fraction and temperature have been interpreted in terms of ion-dipole interactions and structural effects on mixing of IL and solvents. The RedlichKister equation has been fitted to the V E , Dg and Dj S values using a multi-parametric nonlinear regression method. The PFP theory has been applied to correlate the excess molar volumes. The experimental and PFP correlated values of V E are found to be quite close to each other.

“…However, this unjustified shortcoming can lead to misleading results. In Figure 4b, the calculated values of β ex are reported together with the results of their fitting with Equation 6. In adopting Equation 6 as a model fitting we have to take into account that the parameter η, only affects the amplitude of the theoretical curve.…”

“…The investigation of the excess thermodynamic properties in liquid mixtures is a commonly adopted approach to infer information about the nature of the inter-specie interaction [1][2][3][4][5][6][7][8][9][10][11]. In particular, the concentration dependence of the compressibility of a binary mixture is a quantity whose deviations from ideality are assumed able to give direct indications about the attractive or repulsive nature of the inter-specie potential.…”

Résumé -Sur l'origine des quantités thermodynamiques en excès dans les mélanges de liquides -La nature des interactions entre les composants de mélanges liquides a été étudiée par diffusion Brillouin de la lumière. L'étude a porté sur plusieurs systèmes binaires capables de se mélanger sur toute la plage des concentrations. Les déviations de la compressibilité adiabatique par rapport au comportement idéal ont été observées dans chaque cas. Les résultats ont été interprétés dans le cadre d'un modèle théorique bien établi, à savoir le mélange par sphère dure non additive. En dépit du fait que des observations similaires ont été expliquées en termes d'une amélioration des interactions entre les molécules, l'analyse des fonctions thermodynamiques en excès indique que celles-ci sont dues principalement aux effets des volumes exclus et que les différences dans l'interaction intermoléculaire locale agissent en tant que contributions d'ordre plus élevé : cela peut être envisagé de manière générale pour les mélanges de liquides. La conclusion porte sur la réévaluation des données thermodynamiques en excès et sur leur capacité à fournir des informations directes sur les interactions intermoléculaires.

Density, viscosity, surface tension, and excess properties of DSO and gas condensate mixtures

et al. 2017

Disulfide oil (DSO) mostly burned or stored is known as a low-grade byproduct in gas refining industries. This material is highly perilous to environment. A common way to reduce the environmental impact of DSO is blending in a specific ratio with gas condensate stream in gas refinery. This would improve DSO quality and consequently strengthen its unique application. In this work, density, viscosity and surface tension of DSO and gas condensate mixtures were measured and modeled. Viscosity and density of DSO, gas condensate, and their mixtures were measured in temperature range of 283.15-318.15 K. In addition, surface tension was measured at 298.15 K at different volumetric fractions of DSO-gas condensate mixture. Excess molar volume (V E ), viscosity deviation (Dl), deviation of excess Gibbs free energy (DG E ), and excess surface tension (r E ) were determined based on measured properties. Results showed a positive and negative trend for excess molar volume and excess surface tension, respectively. While fluctuation was observed in viscosity deviation and deviation of excess Gibbs free energy and results showed positive and negative values in different mole fraction. In addition, RedlichKister equation is proposed to predict excess properties of DSO and gas condensate mixtures.Keywords DSO Á Gas condensate Á Excess property Á Viscosity Á Gibbs free energy Á Surface tension
