Temperature dependence of the volumetric properties of some alkoxypropanols+n-alkanol mixtures

Volumetric and Acoustic Properties for Binary Mixtures of Dipropylene Glycol Monopropyl Ether with Alkylamines at Temperatures Between 288.15 K and 308.15 K

“…6, evaluated by using the method of least squares with all points weighted equally along with the standard deviations, σ (F(x))are listed in Table 3. Experimental results for V E are plotted against x i and Table 2 continued with the behavior of positive V E results for dipropylene glycol monomethyl ether or dipropylene glycol monobutyl ether + tributylamine [9,10] but is consistent with that of the negative V E values for butylamine, or DBA and dipropylene glycol monomethyl ether, dipropylene glycol monobutyl ether or dipropylene glycol tert-butyl ether + n-alkanol [14][15][16]29]. Moreover, their behavior may be compared with the V E results for mixtures of DPGMME or DPGMBE with alkylamines [9,10] as shown in Fig.…”

“…As a part of our ongoing program of research on thermodynamic and acoustic properties of binary liquid mixtures containing alkoxyethanols or alkoxypropanols, we have recently reported measurements of excess molar volumes, viscosities, and speeds of sound of binary mixtures of alkoxyalkanols with n-alkylamines [7][8][9][10], 1-alkanols [11][12][13][14][15][16], or amides [17]. As a part of this continuing work, the experimental results for the densities, ρ, and speeds of sound, u, are reported in this article for the binary systems of dipropylene glycol monopropyl ether (DPGMPE) with n-butylamine, dibutylamine, and tributylamine over the complete composition range and those of the pure liquid components at atmospheric pressure and temperatures of (288.…”

Excess Molar Volumes and Viscosities for Binary Mixtures of 1‐Alkoxypropan‐2‐ols with 1‐Butanol, and 2‐Butanol at 298.15 K and Atmospheric Pressure

“…The purities of the solvents were further ascertained by comparing their densities and viscosities at 298.15 K with the values reported in the literatures [10][11][12][13][14][15][16] as shown in Table 1. The densities of pure liquids were measured using a single stem pycnometer having a total volume of 8 cm 3 and an internal capillary diameter of about 0.1 cm. The uncertainty in density measurements was 5×10 -3 kg•m -3 .…”

“…So density ρ and viscosity η for binary mixtures are important from both the practical and theoretical viewpoints. Systematic studies of thermodynamic, transport, and acoustic properties of mixtures containing alkoxypropanols with alkylamines, 1,2 or linear alkanols [3][4][5][6][7][8][9] have been carried out in our laboratory with the aim of a better understanding of molecular interactions of the amine or alcohol and the ether at 298.15 K. In our present investigation, we report new experimental data for excess molar volumes E m V and dynamic viscosities η of binary solvent mixtures containing 1-butanol, or 2-butanol with propylene glycol monomethyl ether (1-methoxy-2-propanol), MeOCH 2 CH(OH)Me, propylene glycol monoethyl ether (1-ethoxy-2-propanol), EtOCH 2 CH(OH)Me, propylene glycol monopropyl ether (1-propoxy-2-propanol), PrOCH 2 CH(OH)Me, propylene glycol monobutyl ether (1-butoxy-2-propanol), BuOCH 2 CH(OH)Me, and propylene glycol tert-butyl ether (1-tert-butoxy-2-propanol), t-BuOCH 2 CH(OH)Me over the entire range of composition at 298.15 K and atmospheric pressure. The present study was undertaken to assess whether the thermo-physical properties of the propylene glycol tert-butyl ether＋1-butanol system resemble those of the propylene glycol monobutyl ether＋1-butanol system.…”

Molar Refraction, Thermal Expansivity and Polarizabilities of Aqueous 1-1 Electrolyte Solutions

“…This approach has been recently employed [11][12][13] for binary liquid mixtures. Lorentz-Lorenz (L-L) 4,5 and Eykman (Eyk) 14 mixing rules for refractive index were employed to obtain α using the following equation;…”
