“…The relative permittivity ε r is the crucial parameter in the molecular solvent system and it usually can be used to measure the polarity of molecular solvents. In this work, the values of refractive index, n D , molar volume, V m , and Δ l g H m o (298) were collected from the literature, − and according to eqs – δ μ of some molecular solvents were obtained. These are listed in Table , and the corresponding relative permittivity ε r for these molecular solvents were collected − and also listed in Table .…”

Ionic liquids (ILs) have attracted remarkable attention as a new class of novel reaction medium and soft functional materials in the framework of Green Chemistry, and the polarity of ionic liquids is one of the primary concerns in the scientific community. Here, we introduce a new and simple scale of polarity, δ μ , for ILs. Initially, two kinds of representative ionic liquids, {1-alkyl-3-methyllimidazolium acetate}) are prepared and confirmed by 1 H NMR spectroscopy and 13 C NMR spectroscopy, respectively. Furthermore, a spectroscopic method based on solvatochromic probes is used to obtain the polarity of room temperature ILs (RTILs). In this work we mainly introduce that the scale of solvent polarity, E T (30) values, is determined by means of Reichardt's dye (30), and π* values are determined by N,N-diethyl-4-nitroaniline. Simultaneously, in terms of the values of enthalpy of vaporization, δ μ values of these ILs are predicted. Moreover, the trend of δ μ values of the ionic liquids with the different alkyl chains are the same as the E T (30) and π* values. In addition, the new scale of polarities δ μ of some molecular liquids are also predicted, and the results are in good agreement with relative permittivity, ε r .

“…Excess molar volumes for ternary mixtures of {2-chlorobutane (1) + butylacetate (2) + isobutanol (3)} at T = 298.15 K were calculated using equation (1) and the results were listed in table 5 and graphically shown in figure 4. The excess molar volumes for the ternary system were correlated using the Cibulka equation [20]:…”

Densities, ρ, and viscosities, η, of four binary systems: N,N-dimethyl formamide (DMF) + 1-propanol, DMF + 2-propanol, DMF + butanol and DMF + 1-pentanol have been measured at five different temperatures ranging form 303.15K to 323.15K at an interval of 5K. Excess molar volumes were found to be negative over the entire concentration ranges. The negative excess molar volume decreases with the increase of chain length of alcohol, the magnitude follows the order DMF+ 1-propanol >, + 2-propanol >, + butanol >, + 1-pentanol. The change of viscosity has been found to be sensitive to the chain length of alcohols. Excess viscosities and Grunberg-Nissan interaction parameters have been found to be positive for DMF + 1-propanol and DMF + 2-propanol systems, and negative for other two systems DMF + butanol and DMF + 1-pentanol. The thermodynamic energy of activation; such as, positive ΔG #E each also compatible with the observation.
