Thermodynamics of Mixtures Containing Alkoxyethanols. Part XXVI. Densities, Excess Molar Volumes, Speeds of Sound at (293.15, 298.15, and 303.15) K, and Isentropic or Isothermal Compressibilities at 298.15 K for 2-Methoxyethanol + Alkoxyethanol or 2-Propoxyethanol + Dibutylether Systems

Abstract

Densities, ρ, and speeds of sound, u, for the systems 2-methoxyethanol (2ME) + 2-ethoxyethanol (2EE), or + 2-butoxyethanol (2BE), or + 2-(2-methoxyethoxy)ethanol (22MEE) and for the 2-propoxyethanol (2PE) + dibutylether (DBE) mixture 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 ρ and u values were used to calculate excess molar volumes, V E, at the mentioned temperatures, molar excess heat capacities at constant volume, C V E, at 298.15 K, and deviations from the ideal behavior at 298.15 K of the thermal expansion coefficient, Δα P , and of the isentropic and isothermal compressibilities, Δκ S and Δκ T , respectively. In DBE systems, H E(molar excess enthalpy) and V E decrease with the size of the 2-alkoxyethanol. In 2ME + alkoxyethanol mixtures, these magnitudes increase with the size of the second compound, although their values depend on the number of etheric atoms of this component.

Investigation of Solution Behaviour of an Ionic Liquid in Diverse Cellosolves by Physicochemical Contrivance

“…The purities of the alkoxy alcohols have been checked by measuring their densities and viscosities, which were in good accordance with the supplemented literature values [7][8][9][10][11][12][13] and are shown in Table 2. -3 ; viscosity u (η) = 0.01 mPa; temperature u (T) = 0.01 K; pressure u (P) = 0.01 MPa *Corresponding Author: mahendraroy2002@yahoo.co.in (Mahendra Nath Roy) https://doi.org/10.30799/jacs.180.18040104…”

“…Alkoxy-alkanols (or cellosolves) are very interesting solvents having the ability to form intra-and intermolecular hydrogen bonds with various electrolytes (viz., ILs) [6,7]. They are the most well-known solvents with protic and self-associated properties [8][9][10][11][12][13].…”

Thermophysical Property Measurements and Modeling of (Ether + Alkanol + Hydrocarbon) Mixtures: Binary and Ternary Mixtures (Dibutyl Ether + 1-Butanol + 1-Hexene or + Iso-octane) at 298.15 K

“…These chemicals are utilized without additional purification, with the exception of a precise degassing with an ultrasonication bath to avoid the creation of bubbles. Table shows the experimental (ρ), ( u ), and ( n D ) results for pure components DBE, 1-butanol, 1-hexene, and iso-octane, which are compared to the data presented in refs − and show a significant accord.…”
