  • isothermal vapour liquid equilibrium data for the binary systems 2 propanone 2 butanol or Propanoic Acid
    Fluid Phase Equilibria, 2017
    Co-Authors: Jeremy Pillay, Samuel A. Iwarere, Paramespri Naidoo, David J Raal, Deresh Ramjugernath
    Abstract:

    Abstract Isothermal vapour-liquid equilibrium (VLE) data were measured for 2-propanone + 2-butanol at (333.15 and 353.15) K and 2-propanone + Propanoic Acid at (333.15, 353.15, and 373.15) K. For the sub-atmospheric pressure measurements, a dynamic recirculating VLE glass still operated isothermally was used, whilst a novel recirculating stainless steel of similar architecture, capable of operating at pressures up to 750 kPa was used for measurements above atmospheric pressures. The experimental VLE data for the 2-propanone + 2-butanol system at (333.15 and 353.15) K were correlated to the Wilson and NRTL models using the gamma-phi approach with the Hayden and O'Connell correlation employed for calculating the second virial coefficients. For the 2-propanone + Propanoic Acid system, the considerably more complex iterative procedure of Prausnitz et al. [J.M. Prausnitz, T.F. Anderson, E.A. Grens, C.A. Eckert, R. Hsieh, J.P. O'Connell, Computer Calculations for Multicomponent Vapour-Liquid and Liquid-Liquid Equilibrium, Prentice- Hall, New Jersey, 1980] was utilized to account for Acid dimerization in the vapour phase. In the computational procedure for finding liquid phase activity coefficients, true species vapour phase mole fractions (ηi) are solved for, with the equilibrium association constant, Ki emerging from the computations. The thermodynamic consistency of the data was verified through the point and direct test methods of Van Ness.

  • density speed of sound and refractive index measurements for the binary systems butanoic Acid Propanoic Acid or 2 methyl Propanoic Acid at t 293 15 to 313 15 k
    The Journal of Chemical Thermodynamics, 2013
    Co-Authors: Indra Bahadur, Paramespri Naidoo, Nirmala Deenadayalu, Deresh Ramjugernath
    Abstract:

    Abstract Density, speed of sound, and refractive index for the binary systems (butanoic Acid + Propanoic Acid, or 2-methyl-Propanoic Acid) were measured over the whole composition range and at T = (293.15, 298.15, 303.15, 308.15, and 313.15) K. The excess molar volumes, isentropic compressibilities, excess isentropic compressibilities, molar refractions, and deviation in refractive indices were also calculated by using the experimental densities, speed of sound, and refractive indices data, respectively. The Redlich–Kister smoothing polynomial equation was used to fit the excess molar volume, excess isentropic compressibility and deviation in refractive index data. The thermodynamic properties have been discussed in terms of intermolecular interactions between the components of the mixtures.
