of new synthesized ionic liquids based on 1-octyl-3-methylimidazolium
with glycinate, alaninate, serinate, prolinate, and asparaginate anions
were prepared. 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.
