  • phase equilibria of water methanol Hexyl Acetate mixtures
    Fluid Phase Equilibria, 1997
    Co-Authors: Alberto Arce, Antonio Blanco, Ana Soto, Isabel Vidal
    Abstract:

    Abstract Liquid-liquid equilibrium data at 25, 35 and 45 °C, and isobaric vapour-liquid equilibrium data at 101.32 kPa, were determined for the ternary system water + methanol + Hexyl Acetate. The data were correlated using the Wilson, NRTL and UNIQUAC models and were predicted using the UNIFAC and ASOG methods.

  • excess volumes and refractions and liquid liquid equilibria of the ternary system water ethanol Hexyl Acetate
    Fluid Phase Equilibria, 1993
    Co-Authors: Alberto Arce, Antonio Blanco, Ana Soto, Pilar Souza, Isabel Vidal
    Abstract:

    Abstract Arce, A., Blanco, A., Soto, A., Souza, P. and Vidal, I., 1993. Excess volumes and refractions and liquid-liquid equilibria of the ternary system water + ethanol + Hexyl Acetate. Fluid Phase Equilibria , 87: 347-364. Densities, refractive indices, excess molar volumes and excess molar refractions at 25°C, and liquid-liquid equilibrium (LLE) data at 25, 35 and 45°C, are reported for the system water + ethanol + Hexyl Acetate. NRTL and UNIQUAC equations have been fitted to the experimental data, and the sensitivity of the correlation to changes in the composition of the phases in equilibrium has been analysed. The validity of the parameters obtained from the ternary system data for representation of the binary systems was also assessed.

  • isobaric vapor liquid equilibria of methanol Hexyl Acetate and ethanol Hexyl Acetate
    Journal of Chemical & Engineering Data, 1995
    Co-Authors: Alberto Arce, Antonio Blanco, Jose Martinezageitos, Ana Soto
    Abstract:

    Vapor-liquid equilibria of methanol + Hexyl Acetate and ethanol + Hexyl Acetate mixtures were determined at 101.32 kPa. The data were checked for thermodynamic consistency using Fredenslund's test, correlated using Wilson, NRTL, and UNIQUAC equations for the liquid phase activity coefficients, and compared with the predictions of the group contribution methods UNIFAC and ASOG.

  • densities refractive indexes and excess molar volumes of water methanol Hexyl Acetate and its binary sub mixtures at 298 15 k
    Journal of Chemical & Engineering Data, 1994
    Co-Authors: Alberto Arce, Antonio Blanco, Jose C Perez, Ana Soto
    Abstract:

    In spite of the potential of Hexyl Acetate as a solvent for recovery of methanol from aqueous dilute solutions, no measurements of this ternary mixture have appeared in the open literature. Densities and refractive indices were measured throughout the miscible region for water + methanol + Hexyl Acetate, water + methanol, and Hexyl Acetate + methanol at 298.15 K and atmospheric pressure. Derived excess volumes were correlated using Redlich-Kister polynomials.

  • Synthesis of Hexyl Acetate catalyzed by solid superacid S_2O_8~(2-)/TiO_2
    Shaanxi Chemical Industry, 2002
    Co-Authors: Wu Chang
    Abstract:

    Hexyl Acetate was synthesized by the new type solid superacid S 2O 2- 8 /TiO 2. The effects of preparation conditions of catalyst on catalytic activity and the effects of acid/alcohol molar ratio,amount of catalyst S 2O 2- 8 /TiO 2,and reaction time on the esterification conversion were studied.The optimum condition is :acid/alcohol molar ratio 0.20 ∶ 0.24 ,the amount of catalyst 0.6 g ,reaction time 2 h,the amount of dehydrater benzne 10 ml,reaction temperaure 100 ℃～110 ℃?The esterification conversion was over 96% under the optimum coditions
