Speed of sound of some aliphatic amines with 2-methoxyethanol mixtures at 298.15 K

Abstract

The speed of sound of binary mixtures of 2-methoxyethanol with diethylamine, triethylamine, propylamine, dipropylamine, sec-butylamine and tert-butylamine has been measured as a function of composition at 298.15 K. From the experimental data, values of deviations in the speed of sound (Áu) and isentropic (Á) compressibility from ideality have been calculated. The results for Áu and Á are discussed on the basis of intermolecular interactions between the components of the analysed mixtures.

Studies of Mixing Properties of Binary Systems of 2-Butoxy Ethanol with Amines at 298.15, 303.15, and 308.15 K

“…Literature survey reveals that the selected systems have not been studied yet. However, similar work has been reported by many researchers. − Kinart et al , measured the speed of sound for binary mixtures of 2-methoxy ethanol with amines and the density and relative permittivity for binary mixtures of pyridine with 2-alkoxy ethanols at 298.15 K. Strong intermolecular interactions were confirmed in these liquid mixtures by calculating the excess and deviation properties. Subha et al studied the volumetric and transport behavior of binary mixtures of ethoxy ethanol with amines, namely, n -butylamine, sec -butylamine, tert -butylamine, n -hexylamine, n -octylamine, and cyclohexylamine, at 308.15 K. They calculated and correlated the negative values of the excess molar volume and positive values of deviation in viscosity in terms of intermolecular interactions.…”

Excess molar volumes and deviations of the relative permittivity of the binary mixtures of 2-propoxyethanol with diethylene, triethylene, and tetraethylene glycols at various temperatures

“…We have studied previously the nature and type of intermolecular interactions in binary liquid mixtures containing alkoxyalcohols or polyethylene glycols in terms of the mixing parameters such as excess molar volume, excess molar refractivity, deviations in relative permittivity, deviations in viscosity, and deviations in isentropic compressibility [1][2][3][4][5][6]. The 2-propoxyethanol (PE), diethylene glycol (DEG), triethylene glycol (TEG), and tetraethylene glycol (TET-RAEG) have been used in the present studies.…”

Thermodynamic and physicochemical properties of binary mixtures of nitromethane with {2-methoxyethanol+2-butoxyethanol} systems at T=(293.15, 298.15, 303.15, 308.15, and 313.15)K

“…Therefore, they are necessary for the interpretation of data obtained from thermochemical, electrochemical, biochemical, and kinetic studies. This paper is a part of an ongoing research effort to measure and to characterize the properties of binary mixtures containing 2-alkoxyethanol and aprotic solvent [1][2][3][4][5][6]. Mixtures containing hydroxyethers are very important from a theoretical point of view, not only because of their self-association, but also due to the strong intramolecular effects produced by the presence of -O-and -OH groups in the same molecule [7][8][9][10].…”
