外文摘要：Values of the density and viscosity of the pure ionic liquid n-butylammonium nitrate (N4NO(3)) and its binary mixtures with methanol, ethanol, 1-propanol, and 1-butanol were measured at temperature ranging from T = (293.15 to 313.15) K. The thermal expansion coefficient, molecular volume, standard entropy, and lattice energy of N4NO(3) were deduced from the experimental density results. The temperature dependence of the viscosity of N4NO(3) was fitted to the fluidity equation. Excess molar volumes V-E and viscosity deviations Delta eta for the binary mixtures were calculated and fitted to the Redlich-Kister equation with satisfactory results. Both excess molar volumes and viscosity deviations show negative deviations for (N4NO(3) + alcohol) mixtures. The effect of the temperature and the size of the alcohol on the excess molar volumes and viscosity deviations are discussed and analysed. Other derived properties, such as the apparent molar volume, partial molar volume, excess partial molar volume, thermal expansion coefficient, and excess thermal expansion coefficient of the above-mentioned systems were also calculated.
