Isobaric Vapor−Liquid Equilibrium for Ethanol + Water + Strontium Nitrate
Journal of Chemical & Engineering Data, 1996Co-Authors: Ernesto Vercher, And M. Pilar Peña, Antoni Martínez-andreuAbstract:Isobaric vapor−liquid Equilibrium for ethanol (1) + water (2) + potassium nitrate (3) at various concentrations of salt and with ethanol mole fractions from 0 to 0.642 has been measured at 100.0 kPa. The results were correlated by assuming that the salt was in ionic form and it was associated only with the water.

Pilar Pena, Ernesto Vercher, Antoni Martínez-andreuAbstract:Isobaric Vapor-Liquid Equilibrium for ethanol (1)+ water (2)+ strontium chloride (3) at different mole fractions of strontium chloride has been measured at 100.0 kPa.

Isobaric Vapor-Liquid Equilibrium data for the ethanol-water-potassium acetate and ethanol-water-(potassium acetate/sodium acetate) systems
Journal of Chemical & Engineering Data, 1991Co-Authors: Ernesto Vercher, R. Munoz, Antoni Martínez-andreuAbstract:Isobaric experimental data of Vapor-Liquid Equilibrium for the ethanol-water-potassium acetate system at different mole fractions of potassium acetate (0.060, 0.080, and 0.100) are presented. Also, the Vapor-Liquid Equilibrium for the ethanol-water-(potassium acetate/sodium acetate) (2:1) system at different mole fractions of salt (0.040 and 0.060) is studied. For each system, both the activity coefficient and relative volatility were calculated. The effect of the salt mixture on the Vapor-Liquid Equilibrium is the same as the effect of potassium acetate being alone

Vapor-Liquid Equilibrium calculation of the system water-hydrogen chloride
Fluid Phase Equilibria, 1994Co-Authors: Stefano Brandani, Vincenzo Brandani, Gabriele Di GiacomoAbstract:Abstract Brandani, S., Brandani, V. and Di Giacomo, G., 1994. Vapor-Liquid Equilibrium calculation of the system water-hydrogen chloride. Fluid Phase Equilibria, 92: 67-74. The Vapor-Liquid Equilibrium of the system water-hydrogen chloride has been described. The activity coefficients in the liquid phase are evaluated by an extended Pitzer model, where the reference state for hydrogen chloride is defined according to Henry's law. The results have been compared with those obtained using a modified Engels and Bosen model.

Vapor—liquid Equilibrium of water—trioxane—formaldehyde mixture
Fluid Phase Equilibria, 1991Co-Authors: Stefano Brandani, Vincenzo Brandani, Gabriele Di GiacomoAbstract:Abstract Recently, we have developed a new model for describing vapor—liquid Equilibrium of the water—formaldehyde and methanol—formaldehyde systems. This model superimposes a physical theory onto the chemical theory for describing liquid-phase behavior of formaldehyde in active solvents. Maurer recently reported vapor—liquid Equilibrium data for the water—trioxane—formaldehyde system. The characteristic of this system is the contemporaneous presence of an active (water) and an inert (trioxane) solvent together with formaldehyde. To test our model, we have fitted the experimental data of Maurer using only three adjustable parameters: the zero pressure Henry's constant of formaldehyde in trioxane and, in the expressions for the activity coefficients which account for interactions between water and trioxane and trioxane and formaldehyde, two physical parameters. The results are satisfactory and the thermodynamic model proposed can be used with confidence to describe vapor—liquid Equilibrium of formaldehyde in the presence of an active and of an inert solvent.

Vapor−Liquid Equilibrium of Formaldehyde Mixtures Containing Methanol
Industrial & Engineering Chemistry Research, 1998Co-Authors: Stefano Brandani, Vincenzo Brandani, Ida TarquiniAbstract:A new description of the vapor phase of formaldehyde solutions containing methanol is presented. In contrast with all previous models for these mixtures, it is recognized that the dimer resulting from the formaldehyde−methanol reaction has a relatively high volatility and should be considered present in the vapor phase. The new model is matched to the experimental vapor−liquid Equilibrium data for binary and ternary mixtures containing formaldehyde, methanol, and water. The proposed model represents well vapor−liquid Equilibrium of these reacting mixtures and does not reveal systematic deviations for the ternary system as observed with previous models.
