| Popis: | The 1-ethyl-3-methyl imidazolium alanine ionic liquid was synthesized and characterized by nuclear magnetic resonance (1H NMR) and differential scanning calorimetry (DSC). The TGA results showed the initial decomposition temperature of 1-ethyl-3-methyl imidazolium alanine ionic liquid was about 473.15 K, which indicated that the ionic liquid has relatively good thermal stability. The low-temperature heat capacity data of 1-ethyl-3-methyl imidazolium alanine ionic liquid were tested by a low-temperature adiabatic calorimeter at the temperature range from 80 to 400 K. The solid liquid phase polynomial equations of 1-ethyl-3-methyl imidazolium alanine ionic liquid were obtained by fitting experimental heat capacity data. And the thermodynamic functions of the compound in the experimental temperature range were also calculated. |
