  • liquid liquid equilibrium for water 5 hydroxymethylfurfural 1 pentanol 1 hexanol 1 heptanol systems at 298 15 k
    The Journal of Chemical Thermodynamics, 2019
    Co-Authors: Kyriale V M Cavalcanti, Luz M Follegattiromero, Irede Dalmolin
    Abstract:

    Abstract Liquid-liquid equilibrium (LLE) data for {water + 5-hydroxymethylfurfural (HMF) + 1-pentanol/1-hexanol/1-Heptanol} ternary systems was measured at 298.15 K and 0.1 MPa. The solute selectivity and the capacity of alcohols were evaluated and the results showed that 1-pentanol has better performance than 1-hexanol and 1-Heptanol for HMF recovery from aqueous solutions. The NRTL and UNIQUAC models were used to correlate the liquid-liquid experimental values and the binary interaction parameters obtained were thermodynamically consistent. The root-mean-square deviations (RMSD) between the experimental data measured and the calculated by the NRTL and UNIQUAC models were less than 0.69% for all systems.

  • densities speeds of sound and isentropic compressibilities for binary mixtures of 2 ethyl 1 hexanol with 1 pentanol 1 heptanol or 1 nonanol at the temperature 298 15 k
    Journal of Chemical & Engineering Data, 2010
    Co-Authors: Edward Zorȩbski, Monika Geppertrybczynska, Beata Maciej
    Abstract:

    Densities and speeds of sound for binary mixtures of 2-ethyl-1-hexanol with 1-pentanol, 1-Heptanol, or 1-nonanol were measured over the entire composition range at the temperature 298.15 K by means of a vibrating tube densimeter and the pulse-echo-overlap method. Also, the densities for pure compounds in the temperature range from (288.15 to 318.15) K were measured. From experimental data, the excess molar volumes and excess molar isentropic compressibilities were calculated. The deviations of the speeds of sound were calculated as well. The Redlich−Kister polynomials were fitted to the results, and smooth representations of the results are presented. For the mixtures studied, the negative values of the excess molar isentropic compressibilities over the entire composition range are observed. The values of the excess molar volumes are negative over the entire composition range for mixtures of 2-ethyl-1-hexanol with 1-pentanol or 1-Heptanol. For the mixtures of 2-ethyl-1-hexanol with 1-nonanol, the excess m...
