Isothermal (vapour + liquid) equilibria for (nitromethane or nitroethane + 1,4-dichlorobutane) binary systems at temperatures between (343.15 and 363.15) K

Isothermal (vapor + liquid) equilibrium data are reported for the binary mixtures containing (nitromethane or nitroethane) + 1,4-dichlorobutane) at three temperatures, (343.15, 353.15, 363.15) K. The measurements were performed by means of an ebulliometer which allows sampling from both phases in equilibrium. The experimental data were correlated using the Redlich-Kister, Wilson, NRTL and UNIQUAC excess Gibbs energy models by means of maximum likelihood

Isothermal Vapor-Liquid Equilibria for Nitromethane and Nitroethane + 1,3-Dichloropropane Binary Systems at Temperatures between (343.15 and 363.15) K

Isothermal vaporliquid equilibrium (VLE) data are reported at three temperatures, (343.15, 353.15, and 363.15) K, for the binary mixtures containing nitromethane or nitroethane with 1,3-dichloropropane. For the measurements an all-glass ebulliometer was used, which allows sampling from both phases in equilibrium. The experimental data were correlated using the nonrandom two-liquid (NRTL) and universal quasichemical activity coefficient (UNIQUAC)

Vapour-liquid equilibria for the binary mixtures of methyl ethyl ketone(2-butanone)+ some chloroalkanes at temperatures from 298.15 to 318.15 K. Comparison with disquac model prediction

The vapour pressures of binary mixtures of methyl ethyl ketone (2-butanone) + chloroalkanes (1-chloropentane, + 1,1,1-trichloroethane, + 1,1,2,2-tetrachloroethane) were measured by a static total pressure method, at temperatures between 298.15 K and 318.15 K. The vapour pressures vs. liquid phase composition data have been used to calculate the activity coefficients of the two components, and the excess molar Gibbs energies GE for the mixtures, using

Isothermal vapour-liquid equilibria in cyclohexanone + dichloroalkane binary mixtures at temperatures from 298.15 to 318.15 K

The vapour pressures of binary mixtures of cyclohexanone + dichloroalkane (1,3-dichloropropane and 1,4-dichlorobutane) were measured at temperatures between 298.15 and 318.15 K. The vapour pressures vs. liquid phase composition data were used to calculate the activity coefficients of the two components and the excess molar Gibbs energies GE for the mixtures, using the Barker method and the Redlich–Kister, Wilson, NRTL and UNIQUAC equations, taking

Isothermal vapour-liquid equilibria for 1,2-dichloroethane + nitromethane and + nitroethane binary systems at temperatures between 333.15 – 353.15 K

Isothermal vapour–liquid equilibrium (VLE) data are reported at three temperatures, 333.15, 343.15 and 353.15 K, for binary mixtures containing 1,2-dichloroethane with nitromethane or nitroethane. Use has been made of an ebulliometer which allows sampling from both phases in equilibrium. The experimental data were correlated using the Redlich–Kister, Wilson, NRTL and UNIQUAC excess Gibbs energy models by means of the maximum likelihood method,

Densities and Excess Molar Volumes of the Binary Mixtures of Cyclopentanone with Chloroalkanes at Temperatures between (288.15 and 318.15) K

The experimental densities of binary mixtures of cyclopentanone with 1,1,2,2-tetrachloroethane, 1,1,1-trichloroethane, trichloromethane, 1,2-dichloroethane, 1,3-dichloropropane, 1,4-dichlorobutane, and 1-chlorobutane have been measured at T = (288.15, 298.15, 308.15, and 318.15) K and atmospheric pressure, over the whole composition range. From these results, excess molar volumes, VE, have been calculated and fitted to the Redlich−Kister polynomial

Measurement and theoretical analysis of excess molar volumes of binary mixtures of some chloroalkanes + cyclic ketones between (288.15 – 318.15) K

Excess molar volumes (VE) have been measured for binary liquid mixtures of cyclohexanone or cyclopentanone with 1,1,2,2-tetrachloroethane, 1,1,1-trichloroethane, trichloromethane, 1,2-dichloroethane, 1,3-dichloropropane, 1,4-dichlorobutane and 1-chlorobutane at T = (288.15, 298.15, 308.15, and 318.15) K and atmospheric pressure. The VE data were analysed with the Flory and Prigogine-Flory-Patterson (PFP) statistical theories of solutions. The obtained

(Vapour + liquid) equilibria and excess Gibbs energies of (cyclohexanone + 1-chlorobutane and + 1,1,1-trichloroethane) binary mixtures at temperatures from (298.15 K to 318.15) K

The vapour pressures of binary (cyclohexanone + 1-chlorobutane, + 1,1,1-trichloroethane) mixtures were measured at the temperatures of(298.15, 308.15, and 318.15) K. The vapour pressures vs. liquid phase composition data have been used to calculate the excess molar Gibbs free energies GE of the investigated systems, using Barker’s method.
