Abstract
In this work densities of binary mixtures of {dichloromethane (DCM) +Â n-butylamine (n-BA), or +Â s-butylamine (s-BA), or +Â t-butylamine (t-BA), or diethylamine (DEA), or +Â triethylamine (TEA)}, have been determined under atmospheric pressure as a function of composition and temperature using a vibrating-tube densimeter. The temperatures studied were TÂ =Â 288.15, 293.15, 298.15 and 303.15Â K. The excess molar volumes (VmE), calculated from density data, are negative for the (DCM +Â t-BA, or +Â DEA, or +Â TEA) mixtures and present a sigmoid curve for the (dichloromethane +Â n-BA, or + s-BA) mixtures. The partial molar volumes at infinite dilution of each component (VÌ
iâ) have been determined using three different methods.
