Vapor-liquid equilibria for dichloromethane or chlorobutane+a linear mono-, or diether (diethyl ether, dipropyl ether, methyl butyl ether, 1,2-dimethoxyethane,) or an acetal (diethoxymethane), were determined at 25°C by head-space gas chromatographic analysis of the vapor phase directly withdrawn from an equilibration apparatus. Excess Gibbs energies, GE, activity coefficients at infinite dilution, fi o as well as free energy of solvation, ΔGo, were evaluated for all the systems. A tentative approach is presented based either on an additivity scheme of surface interactions and scaled particle theory to calculate group contribution to the free energy of solvation.

Abstract
Vapor-liquid equilibria for dichloromethane or chlorobutane+a linear mono-, or diether (diethyl ether, dipropyl ether, methyl butyl ether, 1,2-dimethoxyethane,) or an acetal (diethoxymethane), were determined at 25°C by head-space gas chromatographic analysis of the vapor phase directly withdrawn from an equilibration apparatus. Excess Gibbs energies, GE, activity coefficients at infinite dilution, fi o as well as free energy of solvation, ΔGo, were evaluated for all the systems. A tentative approach is presented based either on an additivity scheme of surface interactions and scaled particle theory to calculate group contribution to the free energy of solvation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
