Thermophysical properties of some amino acid-based ionic liquids

In this work some of the amino acid–based ionic
liquids (EmimGlu, EmimHis, EmimAsp) were synthesized
and characterized by NMR, elemental analysis. The
thermophysical properties such as density, viscosity
were measured in the temperature range of T= 293.15
to 353.15 K and refractive index in the temperature
range of T= 293.15 to 333.15 K. The thermal expansion
coefficient values were calculated from the experimental
density values. The thermal degradation behavior was
measured by thermogravimetric analysis (TGA).
