density viscosity and refractive index data for a ternary system of wine congeners Ethyl Butyrate diEthyl succinate isobutanol in the temperature range from 288 15 to 323 15 k and at atmospheric pressure
Journal of Chemical & Engineering Data, 2017Co-Authors: Divna M Majstorovic, Emila M živkovic, Mirjana Lj. KijevčaninAbstract:Density, viscosity, and refractive index data for the ternary system Ethyl Butyrate + diEthyl succinate + isobutanol and binary system Ethyl Butyrate + diEthyl succinate have been measured in the temperature range 288.15–323.15 K, with temperature step of 5 K, and at atmospheric pressure. The measurements were performed on an Anton Paar DMA 5000 digital vibrating tube densimeter, Anton Paar SVM 3000 digital viscometer, and Anton Paar RXA 156 refractometer. Based on the corresponding binary data, as well as ternary data, presented in this work, excess molar volumes (VE), viscosity deviations (Δη), and refractive index deviations (ΔnD) were determined and fitted by the Redlich–Kister and Nagata–Tamura polynomial equations. The influence of mixture composition on values of excess molar volume, deviation functions, and the molecular interactions present in the mixtures was further discussed.

Journal of Chemical & Engineering Data, 2014Co-Authors: Divna M. Bajić, Emila M. Živković, Slobodan S. Šerbanović, Mirjana Lj. KijevčaninAbstract:The density, viscosity, and refractive index of binary mixtures consisting of Ethyl-Butyrate + 1-propanol, 2-mEthyl-1-propanol, 1-butanol, 3-mEthyl-1-butanol, or 1-hexanol have been measured at atmospheric pressure and over the temperature range from (288.15 to 323.15) K. Excess and deviation functions have been calculated from these data and fitted to the Redlich–Kister equation.

Journal of Chemical & Engineering Data, 2003Co-Authors: Mirjana Lj. Kijevčanin, Inês Ribeiro, And Abel G. M. Ferreira, Isabel FonsecaAbstract:The excess molar volumes, VE, viscosity deviations, Δη, and excess surface tensions were calculated from the measured density, viscosity, and surface tension values, σ, over the whole miscibility composition range for the ternary system water + Ethyl Butyrate + methanol and their constituent binaries, at 303.15 K and atmospheric pressure. The liquid interfacial tension was measured in the liquid−liquid equilibrium range at the same conditions of temperature and pressure. A Redlich−Kister type equation was used to correlate binary and ternary VE and Δη data. For the correlation of the surface tension of binary and ternary data, the Santos et al. equation was used. The interfacial tension was correlated with the Li and Fu equation.

density refractive index and speed of sound at 298 15 k and vapor liquid equilibria at 101 3 kpa for binary mixtures of methanol Ethyl Butyrate and vinyl acetate Ethyl Butyrate
Journal of Chemical & Engineering Data, 2002Co-Authors: José M. Resa, Cristina González, Salomé Ortiz De Landaluce, Juan LanzAbstract:Densities, refractive indices, and speeds of sounds at 298.15 K, and isobaric vapor−liquid equilibria data at 101.3 kPa were reported for the binary mixtures containing methanol + Ethyl Butyrate and vinyl acetate + Ethyl Butyrate. Excess molar volumes, refractive index deviations, and changes of speed sound on mixing were calculated from the measurement results and fitted with Redlich−Kister polynomials. VLE experimental data were satisfactorily tested for thermodynamic consistency by means of a modified Dechema test. The activity coefficients were correlated with the Margules, van Laar, UNIQUAC, NRTL, and Wilson equations. The ASOG model was also used for prediction.

Phase Equilibria for Three Ternary Systems (Water + n-Propanol + n-Butyl Acetate, Ethyl Butyrate or n-Pentyl Acetate) at T = (293.15, 303.15, 313.15) K
Journal of Solution Chemistry, 2021Co-Authors: Wenfeng Peng, Yao ChenAbstract:The experimental liquid phase compositions of the ternary systems (water + n-propanol + n-butyl acetate, Ethyl Butyrate or n-pentyl acetate) were measured at T = (293.15, 303.15 and 313.15) K under atmospheric pressure. The thermodynamic modified and extended UNIQUAC models were applied to correlate and analyze the experimental values. Ternary phase diagrams at the experimental temperatures were plotted and compared. The linear trend of the measured liquid–liquid equilibrium data was confirmed by using the Bachman equation. Distribution coefficients and separation factors were applied to evaluate extracting capability of n-butyl acetate, Ethyl Butyrate and n-pentyl acetate to separate n-propanol from (n-propanol + water) solutions.

The consistency of the experimental LLE data was further ascertained by applying Hand and Bachman equations. The extraction capability of Ethyl Butyrate and n-pentyl acetate was estimated by distribution coefficients and separation factors. The extraction efficiencies of Ethyl Butyrate and n-pentyl acetate were compared with those of other extraction agents such as isobutyl acetate, butyl acetate, butyl propionate and sec-butyl acetate. And extraction performance of Ethyl Butyrate and n-pentyl acetate in the extraction of 2-propanol from 2-propanol-water solutions was confirmed.
