Densities and excess molar volumes of the solvent (ethane-1,2-diol + 2-methoxyethanol + water) fromT=263.15 K toT=353.15 K

Densities and derived thermodynamic properties of (2-methoxyethanol+1-propanol, or 2-propanol, or 1,2-propandiol) at temperatures from T=(293.15 to 343.15)K

“…This behaviour may be explained by the relative energetically favourable rotameric conformers[10,25] (anti and gauche). The observed V E m values suggest a stronger interaction in the system 2-methoxyethanol with 2-propanol than in that containing 1-propanol.…”

Refractive indices of binary mixtures of (1,2-dichloroethane + 2-chloroethanol) at various temperatures

“…In fact, the excess molar volume V E m > 0 at all experimental conditions, (17) while the excess refractive index (figure 2) is negative. By combining these opposite behaviours into the R E property, we observe a predominance of the V E m contribution at low temperatures, an offset of the two effects around T = 323 K, and an obvious predominance of the n D contribution at high temperatures.…”

“…where ρ is the liquid density, (17) ε 0 is the relative permittivity of vacuum, and ε and ε ∞ are the static (taken from reference 7) and high-frequency permittivities of the mixtures, respectively. For the latter the value ε ∞ ≈ 1.1·n 2 D was used, according to literature suggestions.…”

“…where ρ is the density, (17) n is the refractive index, and x i and M i represent the mole fraction and the molar mass of component i, respectively. The calculated R values are in the range 17.668 (pure CE at T = 273.15 K) ≤ R/(cm 3 · mol −1 ) ≤ 21.144 (pure DCE at T = 343.15 K), and are plotted in figure 3 as a function of the CE mole fraction x 2 at T = 273.15 and T = 343.15 K. An inspection of figure 3 shows that the electronic polarization of the mixtures decreases monotonously with CE composition.…”
