“…Thermodynamic and physico-chemical properties of binary liquid mixtures of 1,4-dioxane with water have been reported [2,3,11,37]. Therefore, the observed negative excess volumes [1-3, 9, 10, 38] are an indication of strong heteromolecular interactions in the liquid mixtures and, according to Fort et al [39], this can be attributed to specific interactions between dioxane and water molecules as investigated in some recent structural studies [14], 0.7870 [36] [1, 2, 7, 8], and non-specific interactions (dipole-dipole, dipole-induced-dipole, dispersion interactions) that depend on temperature [39].…”

“…This article is a continuation of earlier works that involve the study of 1,4-dioxane + water (D-W) binary liquid mixtures [1][2][3][4][5][6]. The 1,4-dioxane + water solvent mixture is interesting, and a great deal of good work has been reported by many researchers [7][8][9][10][11][12][13][14] with different experimental methods in order to understand the hydrogen bonding interactions and correlation length between unlike molecules in cluster formation.…”

“…So, in order to obtain the true activation energy E a (T ) as a function of temperature, we use the following equation: Fig. 1 Arrhenius activation energy E a of the pure liquid components versus the absolute temperature T as given in this work, previous works [2][3][4][5], and from the literature [12,13,[23][24][25][26][27][28][29][30][31][32][33][34][35][36]: (") water, (!) dioxane with the ln η(T ) values fitted by a least-squares optimization procedure to a fourth-order polynomial in the reciprocal of the absolute temperature (1/T ).…”

“…Consequently, the same behavior is also observed for the variation of the η ∞ values with temperature. In the same way, the Arrhenius activation energies can be closely related to the enthalpy of vaporization vap H of the pure component, and their viscosity can be predicted for both gases and liquids [1,2,6,42]. In fact, some authors use Eq.…”

The knowledge and prediction of physicochemical properties of binary liquid mixtures is of great importance for understanding intermolecular interactions. Viscosities (η) have been investigated by using density (ρ) and kinematic viscosity (ν) measurements for 1,4-dioxane + water (D-W) mixtures over the entire range of mole fractions under atmospheric pressure, at 311.15, 316.15 and 320.15 K, in order to increase the studied temperatures range available from the literature and to improve the investigations. The viscosity Arrhenius activation energy of 1,4-dioxane + water mixtures was calculated from the present experimental viscosity measurements, and those presented in a previous work at only four temperatures, and for three temperatures in the present work, over the entire range of composition in the temperatures range from 293.15 to 323.15 K. Based on the partial molar activation energy from the Arrhenius equation for viscosity, interactions between water and 1,4-dioxane molecules are discussed. Comparison between some reduced Redlich-Kister functions covering the composition domain shows the existence of two distinct behaviors.

“…Additionally, the study of derivative functions such as excess molar volume, partial molar volume and excess partial molar volumes of binary liquid mixtures is useful in understanding the nature and strength of intermolecular interactions between the component molecules (Ali et al, 2004;Besbes et al, 2009;Nain et al, 2008).…”

-The density of the pure component (n-hexadecane), pure pseudo-components (coconut biodiesel and diesel) and pseudo-binary mixtures of coconut biodiesel with n-hexadecane (or + diesel) were measured at temperatures 293.15, 313.15, 333.15, 353.15 and 373.15 K and atmospheric pressure, over the entire composition range (mole fractions from 0.1 to 0.9, with a step de 0.1). Densities were determined using an Anton Paar SVM 3000 viscodensimeter. Experimental density values decreased with the increase of the temperature. The excess molar volumes of the pseudo-binary mixtures were calculated by using the experimental values of density. Excess molar volumes were correlated with the Redlich-Kister polynomial expansions. Excess molar volumes show positive and negative values in the two systems studied. Excess partial volumes at infinite dilution were calculated for coconut biodiesel, n-hexadecane and diesel in the mixtures studied.

Spraying Characteristics of Alcohol‐Coal‐Water Slurries with Low Coal Content

et al. 2022

The results of spraying characteristics of alcohol‐coal‐water slurries are presented. It has been experimentally proved that the lowest viscosity value of the studied slurries varies from 54 to 329 mPa s. The density value of alcohol‐coal‐water slurries decreases to 1130 kg m−3 when the content of isopropyl alcohol in the fuel composition is 8 wt %. The largest value of jet spraying angle corresponds to alcohol‐coal‐water fuel with an isopropyl alcohol content of 8 wt %. The number of sufficiently large droplets decreases in comparison with a typical two‐component coal‐water fuel. The calorific value of alcohol‐coal‐water slurries rises when the third liquid fuel component is introduced into the composition of coal‐water fuel.
