Volume of Mixing, Speed of Sound, and Viscosity of Butyl Acetate with Xylenes at 303.15 K

Abstract

The volume of mixing, speed of sound, and viscosity of binary liquid mixtures composed of butyl acetate + o-xylene, + m-xylene, and + p-xylene have been measured at 303.15 K. The excess volumes and deviations in isentropic compressibility and viscosity are discussed in terms of molecular interaction between like and unlike components.

Topological and thermodynamic investigations of molecular interactions in binary mixtures: Molar excess volumes and molar excess enthalpies

“…A number of experimental as well as theoretical studies on thermodynamic properties for alkyl ester with alkanes [1][2][3][4][5][6][7][8][9], aromatic hydrocarbons [8][9][10][11][12][13][14][15][16][17], alcohols [18,19], chloroalkane [20] and acetonitrile [16,21] have been reported in literature. Among them, systemic data for alkyl ester + aromatic polar solvent are relatively rare [10][11][12][13][14][15][16][17].…”

“…Among them, systemic data for alkyl ester + aromatic polar solvent are relatively rare [10][11][12][13][14][15][16][17]. Alkyl esters are characterized by dipole-dipole interactions in the pure state [1][2][3].…”

“…The additions of inert solvents like alkane generally break the orientation order of pure alkyl esters to give the positive value of excess thermodynamic functions like excess molar volume, V E , excess molar enthalpy, H E , and excess molar Gibb's free energy, G E [4,5]. However, these values become very less and even negative in the mixtures of alkyl esters + aromatic hydrocarbons [10,11,14,15]. Specific interactions of dipole-induce dipole type are postulated to account for such behavior [14,15].…”
