Study on the Properties of Amino Acid Ionic Liquid EMIGly

In terms of standard addition method, the density and surface tension of an amino acid ionic liquid EMIGly(1-ethyl-3-methylimidazolium aminoacetate) were measured under dry argon atmosphere in the temperature range of 288.15−343.15 K. The properties of volume and surface for pure EMIGly were discussed in terms of the interstice model and Glasser's theory. The thermal expansion coefficient α = 5.03 × 10-4 K-1 calculated using interstice model is in good agreement with α (experimental) = 5.20 × 10-4 K-1.
