Densities, Viscosities, Sound Speeds, Refractive Indices, and Excess Properties of Binary Mixtures of Isoamyl Alcohol with Some Alkoxyethanols

Abstract

Densities and viscosities were measured for binary mixtures of isoamyl alcohol with 2-methoxyethanol, 2-ethoxyethanol, and 2-butoxyethanol over the entire range of composition at 303.15 K, 313.15 K, and 323.15 K and ultrasonic speeds and refractive indices at 303.15 K under atmospheric pressure. From the experimental values of density, viscosity, ultrasonic speed, and refractive index, the values of excess molar volume (V E ), viscosity deviations ( η), deviations in isentropic compressibility ( K S ), and excess molar refraction ( R) have been calculated. The excess or deviation properties were found to be either negative or positive, depending on the molecular interactions and the nature of liquid mixtures.

Ultrasonic Studies on Binary Liquid Mixtures of Methyl Acrylate With 2-Alkoxy Ethanols at 308.15 K.

“…Further the data suggests that the strength of complex formation between unlike molecules increase from 2-Methoxy Ethanol (2ME) to 2-Butoxy Ethanol (2BE). This conclusion is supported by Fort and Moore [15], Mahendranath Roy [16], Douhéreta [17] and Sastry et al [18].…”

Influence of Tetra Alkyl Ammonium Cation and Temperature on Molecular Interactions Involves in Binary Liquid Mixtures of Dioxane and DMF at Various Temperatures

“…In many chemical engineering areas such as process design, oil fraction characterization, and others, accurate estimation of thermodynamic, optical, and ultrasonic properties as a function of composition and temperature is particularly important [1]. In recent years, ultrasonic techniques has become a powerful tool in providing information regarding the molecular interactions of liquid mixtures owing to its ability of characterizing physiochemical behavior of the medium [2][3][4][5][6][7][8][9][10]. The experimental values of acoustical parameters allow us to establish a new predictive structural interaction that tells about the structural information of the liquid mixtures at various temperatures that are desirable for many chemical industries in a fast reliable and economical way [11][12][13][14][15].…”
