Thermodynamics of Mixtures Containing Alkoxyethanols. XXIV. Densities, Excess Molar Volumes, and Speeds of Sound at (293.15, 298.15, and 303.15) K and Isothermal Compressibilities at 298.15 K for 2-(2-Alkoxyethoxy)ethanol + 1-Butanol Systems

Abstract

Densities, F, and speeds of sound, u, of systems formed by 2-(2-methoxyethoxy)ethanol (22MEE), 2-(2ethoxyethoxy)ethanol (22EEE), or 2-(2-butoxyethoxy)ethanol (22BEE) and 1-butanol (1-BuOH) have been measured at (293.15, 298.15, and 303.15) K and atmospheric pressure using a vibrating-tube densimeter and sound analyzer (Anton Paar model DSA-5000). The F and u values were used to calculate excess molar volumes, V E , at the mentioned temperatures and deviations from the ideal behavior at 298.15 K of the thermal expansion coefficient, ∆R P , and of the isentropic and isothermal compressibilities, ∆κ S and ∆κ T , respectively.

Thermodynamics of (1-alkanol+linear monoether) systems

“…At this end, and as continuation of the previous experimental works (see, e.g. [31][32][33]), we provide here data on q and u and on related quantities such as V E , or Da p , or Dj S for (1-heptanol, or 1-octanol, or 1-decanol + dibutylether) systems.…”

“…In the previous works, we have determined volumetric, and ultrasonic data of mixtures formed by 2-methoxyethanol (2ME), 2-ethoxyethanol (2EE), 2-propoxyethanol (2PE), 2-butoxyethanol (2BE), 2-(2-methoxyethoxy)ethanol (22MEE); 2-(2-ethoxyethoxy)ethanol (22EEE) or 2-(2-butoxyethoxy)ethanol (22BEE), and dibutylether [33,96]. These hydroxyethers are homologous to the 1-alkanols considered here (from 1-butanol to 1-decanol).…”

Density, Viscosity, and Refractive Index for Water + 2-Butoxyethanol and + 2-(2-Butoxyethoxy)ethanol at Various Temperatures

“…A reasonable agreement was found among our experimental results and literature data. [21][22][23][24][25][26][27][28] The experimental results of densities, viscosities, and refractive indices for two binary systems: (1 -x) water + x C 4 E 1 and (1 -x) water + x C 4 E 2 as a function of mole fraction of C i E j , x, at temperatures ranging from (283.15 to 323.15) K are given in Tables 3 and 4, respectively. Note that the lower critical solution temperature (LCST) of the water + C 4 E 1 system is 322.15 K and that the system exhibits liquid-liquid coexistence when the system temperature is above its LCST.…”

Excess Molar Volume and Viscosity Deviation for the Binary Mixture of Diethylene Glycol Monobutyl Ether + Water from (293.15 to 333.15) K at Atmospheric Pressure

“…On the other hand, hydroxyethers are nonionic amphiphile molecules, very effective as surfactants with a large number of applications. 2 Short-chain polyethylene glycol monoalkylethers are used in various biotechnical and biomedical applications, constituting a simple model of biological systems. 3 Also, in the last years, some authors have proposed new organic working pairs containing ethylene glycol ethers as absorbent fluids for absorption heat pumps and chillers.…”
