Study on the Properties of Amino Acid Ionic Liquid EMIGly

Abstract

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 alpha = 5.03 x 10(-4) K(-1) calculated using interstice model is in good agreement with alpha (experimental) = 5.20 x 10(-4) K(-1).

The estimation of physico-chemical properties of ionic liquid N-propylpyridine rheniumate

“…In searching others efficient catalyzers, the rheniumate ionic liquid come into our sight. As a continuation of our previous investigations [3,[8][9][10][11], in this paper, we synthesized a new, air-and water-stable IL TPReO 4 (N-propylpyridine rheniumate) which contains rare metal Rhenium; measured density and surface tension of the IL in the temperature range of 293. 15 were distilled and then stored over molecular sieves in tightly sealed glass bottles, respectively.…”

“…There is a widespread interest in room temperature ionic liquids (ILs) as new, non-volatile solvents in both academia and industry in research areas as diverse as electrochemistry, synthesis, catalysis, materials, separations, and biotechnology [1][2][3][4][5][6][7]. But the accurate values for many fundamental physical-chemical properties of the ILs were either scarce or even absent, which were very important for the academic study and industrial process.…”

Synthesis and Thermophysical Properties of Hydrogensulfate Based Acidic Ionic Liquids

“…As the equation does not require further structural information, it can be used to calculate the standard entropy S 0 of both amorphous solids and ILs. From the molecular volumes (V m ) calculated previously, the standard entropy of the present ILs were calculated using the following equation [27,28].…”

“…The standard entropies calculated within the range of 283.7-409.6 JÁmol -1 ÁK -1 are presented in Table 6 [13,24,27]. The lattice energy of a salt is associated with the potency of interactions of its ions and predicts their relative stabilities.…”

Study On The Structures And Interactions Binary System Composed By The Ionic Liquids [Bmim][Ala] and Water /Methanol Using The Vibrational Spectra

“…A set of theoretical methods have now been used to study ILs. Traditional molecular dynamics simulations, first-principles molecular dynamics simulations and electronic structure methods have been applied to ILs to obtain useful information on ILs [19,20].…”
