Ultrasonic Speeds, Molar Excess Volumes and Adiabatic Compressibilities of the 1-Butanol + Glycerol System at 298.15 K

Abstract

Ultrasonic speeds in and densities of mixtures of 1-butanol with glycerol have been measured at 298.15 K. The excess values of the molar volume and molar adiabatic compressibility (as well as adiabatic compressibility coefficient) were estimated. Also deviations of the ultrasonic speeds from the values calculated for ideal mixtures were determined. All the excess quantities are expressed by the Redlich-Kister polynomials and disscused in terms of molecular interactions.

Some Physicochemical Properties of Binary Mixtures of Glycerol with Butanol Isomers in the Temperature Range 293.15–318.15 K and Ambient Pressure

“…Therefore, in the above systems, V E becomes more negative with increasing temperature. The same trend was observed in the results published by Zorebski, concerning the excess molar volume, V E , for the binary mixture (glycerol + 1-butanol) at 298.15 K. The estimated AAPDs = 22%. The deviations between the experimental and the literature data are caused by the differences of the used instruments and the operating process.…”

“…5 In this work, we report the densities, the viscosities, and their derived properties, the refractive indices, and infrared (IR) spectra of binary mixtures of glycerol with 1-butanol, 2butanol, iso-butanol, and tert-butanol at several temperatures and atmospheric pressure in order to interpret their molecular behavior, the degree of their deviation from ideality, the composition and temperature dependences, and the effects of structure and position of the OH group. A survey of the open literature reveals that excess molar volumes for glycerol with 1-butanol have been previously reported but only at 298.15 K. 6 However, some common data regarding the binary mixture glycerol + tert-butanol at certain temperatures, later published by Egorov and Makarov. 7 and by Aniya et al, 8 were used as a comparison.…”

Thermodynamic and transport properties of (1-Butanol+1,4-Butanediol) at temperatures from (298.15 to 318.15)K

“…The Dc and c D differ in magnitude and sign: the first one is negative and the second one positive over the whole concentration range. Similar results were also observed for previous investigated binary mixtures of 1-alkanol with polyols [2,16,49,50]. It is also interesting to note that for the system under test the positive c D curves are accompanied by negative K E S curves.…”

Thermodynamic and transport properties of (1,2-ethanediol+1-nonanol) at temperatures from (298.15 to 313.15)K

“…Simultaneously, for the system under test the absolute values of c D are very small in comparison with those for Dc and c DNB . Similar results (for c D and Dc) were observed also for the earlier investigated binary mixtures with highly associated polyols [28,39,40]. It is also interesting to note, that in these mixtures positive c D curves are always accompanied by negative K E S ones.…”
