Mixing Properties for Binary Liquid Mixtures of Methyl <i>tert</i>-Butyl Ether with Propylamine and Dipropylamine at Temperatures from (288.15 to 308.15) K

Abstract

Densities and sound velocity have been measured over the whole composition range for the binary liquid mixtures of methyl tert-butyl ether with propylamine and dipropylamine using an Anton Paar DSA 5000 density and sound analyzer at temperatures of (288.15, 293.15, 298.15, 303.15, and 308.15) K and atmospheric pressure. From these densities and speeds of sound, excess molar volumes and excess isentropic compressibility were calculated. All of the properties were fitted to Redlich−Kister equation. The variation of these properties with composition and temperature of the mixture is discussed in terms of molecular interactions.
