Vapourx2013;liquid equilibria, azeotropic data, excess enthalpies, activity coefficients at infinite dilution and solidx2013;liquid equilibria for binary alcoholx2013;ketone systems
摘要
Isothermal vapourx2013;liquid equilibria (VLE), solidx2013;liquid equilibria and excess enthalpies have been measured for the systems cyclohexanone + cyclohexanol and 2-octanone + 1-hexanol. Additionally in this paper binary azeotropic data at different pressures for 1-pentanol + 2-heptanone and 1-hexanol + 2-octanone have been determined with the help of a wire band column. Furthermore activity coefficients at infinite dilution for methanol, ethanol, 1-butanol and 1-propanol in 2-octanone at different temperatures have been measured with the help of the dilutor technique. These data together with literature data for alcoholx2013;ketone systems were used to fit temperature-dependent group interaction parameters for the group contribution method modified UNIFAC (Dortmund) and the group contribution equation of state VTPR.
