Experimental isothermal (vapour+liquid) equilibrium (VLE) data are reported for the binary mixture containing 1-butyl-3-methylimidazolium iodide ([bmim]I) + 1-butanol at three temperatures: (353.15, 363.15, and 373.15) K, in the range of 0-0.22 liquid mole fraction of [bmim]I. Additionally, refractive index measurements have been performed at three temperatures: (293.15, 298.15 and 308.15) K in the whole composition range. Densities, excess molar

Additionally, refractive index measurements have been performed at two temperatures, 298.15 and 308.15 K in the whole composition range. Densities, excess molar volumes,
Read moreExcess Gibbs energies, GE, for ten binary systems containing nitromethane or nitroethane + 1-chlorobutane, + 1-chloropentane, + 1,2-dichloroethane, +1,3-dichloropropane, and + 1,4-dichlorobutane are interpreted in terms of the DISQUAC group contribution model. The systems are characterized by three types of contact surface: nitro (NO2), chloro (Cl) and alkane. The interchange energy parameters of the alkane/NO2 and alkane/Cl contacts were determined

The derived excess molar volumes, VE, are positive for the nitromethane + 1,1,1-trichloroethane, +
Read moreThe vapour pressures of binary mixtures of cloroalkane (1-chlorobutane, 1-chloropentane) + nitromethane or nitroethane were measured 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 Barker’s method.
