摘要:
A new amino acid ionic liquid (AAIL) based on glutamic acid, 1-butyl-3-methylimidazolium glutamine (BMIGlu), was prepared by Fukumoto's method and characterized by H-1 NMR, differential scanning calorimetry (DSC), and Karl Fischer moisture titration techniques. The density and surface tension of BMIGlu were measured in the temperature range of (308.15 to 343.15) K by the standard addition method (SAM), and then the values of pure BMIGlu were obtained through the linear extrapolation. Furthermore, the volume and surface properties were also discussed.
