Densities and Refractive Indices of Binary Mixtures of Benzene with Triethylamine and Tributylamine at Different Temperatures

Abstract

Experimental densities, ρ, and refractive indices, n D for binary liquid mixtures of benzene with triethylamine (TEA) and tributylamine (TBA) have been measured as a function of composition in the temperature range from 278.15 to 318.15 K. The excess molar volume, V E , and its temperature dependence, dV E /dT for the binary mixtures were calculated using the experimental data. The values of V E for the mixtures were also estimated by using the Flory statistical theory and refractive index.

Ultrasonic and viscometric study of molecular interactions in binary mixtures of aniline with 1-propanol, 2-propanol, 2-methyl-1-propanol, and 2-methyl-2-propanol at different temperatures

“…The ultrasonic speeds in pure liquids and in their binary mixtures were measured using a single-crystal variable-path multifrequency ultrasonic interferometer operating at 3 MHz by the method described elsewhere [4][5][6][7][8][9][10][11]. The ultrasonic speed data were reproducible within ±0.03%.…”

“…The derivative, (∂K E s /∂x 1 ) T,p in Eqs. (8) and (9) was obtained by differentiation of Eq. (6) on substituting K E s for Y E , which leads to the following equations forK m,1 andK m,2 : …”

“…In previous papers [4][5][6][7][8][9][10][11] we have reported the studies on volumetric, transport, and acoustic properties of binary mixtures containing alkanols. Here we report the results of our study on acoustic and transport properties of binary mixtures of aniline with 1-propanol, 2-propanol, 2-methyl-1-propanol and 2-methyl-2-propanol, over the entire composition range at different temperatures.…”

Molecular interactions in binary mixtures of formamide with 1-butanol, 2-butanol, 1,3-butanediol and 1,4-butanediol at different temperatures: An ultrasonic and viscometric study

“…Alkanols are of interest in their own right and serve as simple examples of biologically and industrially important amphiphilic materials [3]. In previous papers [4][5][6][7][8][9][10][11] we have studied the volumetric, acoustic and transport properties of non-aqueous binary mixtures containing alkanols. Here we report the results of our studies on acoustic and transport properties of binary mixtures of FA with 1-butanol, 2-butanol, 1,3-butanediol, and 1,4-butanediol, over the entire composition range at various temperatures.…”

Densities and Volumetric Properties of Binary Mixtures of Aniline with 1-Propanol, 2-Propanol, 2-Methyl-1-Propanol, and 2-Methyl-2-Propanol at Temperatures from 293.15 to 318.15 K

“…In previous articles [4][5][6][7][8][9][10][11] we have reported studies on volumetric, transport, and acoustic properties of binary mixtures containing alkanols. The present work deals with the volumetric behavior of binary mixtures of aniline with 1-propanol, 2-propanol, 2-methyl-1-propanol, and 2-methyl-2-propanol over the entire composition range at temperatures from 293.15 to 318.15 K. Aniline molecules are polar (µ = 1.51 D at 298.15 K) [12] and self-associated through hydrogen bonding of their amino groups [13], and alkanol molecules are polar and self-associated through hydrogen bonding of their hydroxyl groups [14].…”
