Their thermophysical properties (density, viscosity, surface tension, and heat capacity) were measured at various temperatures and atmospheric pressures. Physicochemical properties such as thermal expansion coefficient values, molecular volume, standard molar entropy, and lattice energy standard were also determined using empirical methods. The effects of anions on the studied properties were further analyzed. 2015-06-11 00:00:00 Ionic Liquids molar entropy Physicochemical Properties thermophysical properties asparaginate anions surface tension heat capacity expansion coefficient values lattice energy Physicochemical properties
