Mixing Properties of the Binary Mixtures of Acetone, Methanol, Ethanol, and 2-Butanone at 298.15 K

Excess molar volumes, and changes of isentropic compressibilities of ternary { acetone+ methanol +( 2-methyl-1-propanol, or 3-methyl-1-butanol)} at T= 298.15 K

“…Additional information about the experimental technique was provided in a previous work. (3) Accuracy in the calculation of mole fractions, excess molar volumes, and changes of isentropic compressibilities on mixing were estimated to better than ±10 −4 , ±9 · 10 −3 cm 3 · mol −1 , and ±1 TPa −1 , respectively. (6) 1187.6 NA 3-Methyl-1-butanol 0.8060 0.8070 (6) 1233.9 NA…”

“…A good agreement between the measured, and theoretical values was obtained with these methods. (3,4) …”

“…In this paper, we report experimental data on the densities and speeds of sound of ternary {acetone + methanol + (2-methyl-1-propanol, or 3-methyl-1-butanol)} at the temperature 298.15 K, and atmospheric pressure, over the whole range of the ternary composition. In previous works, the mixing properties for the binaries {(acetone + methanol), (3) (acetone + 2-methyl-1-propanol), (methanol + 2-methyl-1-propanol), (acetone + 3-methyl-1-butanol), and (methanol + 3-methyl-1-butanol)} (4) were presented. The isentropic compressibilities of solutions were calculated by using the Laplace equation, employing the experimental data.…”

Thermodynamics of (anisole + benzene, or toluene, orn-hexane, or cyclohexane, or 1-butanol, or 1-pentanol) atT= 298.15 K

“…One of the research activities of our group is the identification and study of alternative separation agents in modified rectification processes. (1)(2)(3)(4) In this way, the first step is the thermodynamic characterization of the mixtures involved into the separation problem. In this paper, we present speeds of sound, densities, and refractive indices at T = 298.15 K of (anisole + benzene, or toluene, or n-hexane, or cyclohexane, or 1-butanol, or 1-pentanol) as well as the corresponding derived magnitudes (changes of isentropic compressibilities on mixing, excess molar volumes, and changes of refractive indices on mixing).…”

Thermodynamic properties of the system (acetone + methanol+n -heptane) atT= 298.15 K

“…The present paper presents experimental densities, refractive indices on mixing, isentropic compressibilities, and derived properties of the ternary mixture (acetone + methanol + n-heptane), which have been measured as a function of the mole fraction at T = 298.15 K and atmospheric pressure. The corresponding binary mixtures were studied previously (3,4) by means of the computed Nagata fitting parameters, (5) the ternary partial excess molar volumes were calculated, the corresponding limiting pure component excess volumes being evaluated and commented upon. In the last few years, a a To whom correspondence should be addressed.…”
