Internal pressure and cohesive energy density for binary non-electrolyte mixtures

Internal pressures and cohesive energy densities of binary liquid mixtures of n-pentane+dichloromethane, n-pentane+methylacetate, 2-propanol+methylacetate and n-bytylamine+1,4-dioxane at 25°C have been evaluated from molar volumes surface tensions and enthalpies. The data obtained provide information about interactions in the binary liquid mixtures which can be correlated with results from other thermodynamic properties.Presented at the VI Congreso Argentino de Fisicoquímica, Santiago del Estero, Argentina, 1989.
