Estimation of Physicochemical Properties of Ionic Liquids 1-Alkyl-3-methylimidazolium Chloroaluminate

Abstract

The density and surface tension of ionic liquids [C(2)mim][AlCl(4)] (1-ethlyl-3-methyl imidazolium chloroaluminate) and [C(6)mim][AlCl(4)] (1-hexyl-3-methylimidazolium chloroaluminate) were measured in the temperature range from 283.15 to 338.15 +/- 0.05 K. In terms of these experimental results, the estimation of physicochemical properties of 1-alkyl-3-methylimidazolium chloroaluminate ([C(n)mim][AlCl(4)], n = 1-6) was carried out. With the use of the parachor, the values of surface tension of the ILs were predicted. In terms of Glasser's theory, the standard molar entropy, lattice energy, and surface properties of the ILs were estimated. With the use of Kabo's method and Rebelo's method, the molar enthalpy of vaporization of the ILs, Delta(l)(g)H(m)(0), was predicted. According to the interstice model, the values of the thermal expansion coefficient of the ILs were also estimated. Since the magnitude order of the thermal expansion coefficient estimated by the model is in good agreement with that measured experimentally, this result means that the interstice model is reasonable.

Study on thermodynamic properties of a new air and water stable ionic liquid based on metal rhenium

“…This will allow the design of new ILs with specific properties tailored for particular applications, without the need for time-consuming trial and error syntheses. As a continuation of our previous investigation [9,10], in this paper we discuss that (i) density and surface tension of the IL were measured over the temperature range of (293.15 to 343.15) K, (ii) in terms of the Glasser theory of IL [11] and parachor [12], the physico-chemical properties of homologous compounds of ionic liquids, [C n py][ReO 4 ] (n = 1, 2, 3, 4, 5, 6), were predicted, and (iii) using estimated values of molar volume and surface tension, the thermal expansion coefficients of the homologous compounds were predicted by interstice model [6].…”

“…In contrast, there have been relatively few studies on fundamental physicochemical properties of ILs, which are extremely important for their applications [3]. Recently, there is a developing trend in the literature towards estimation of physicochemical properties for ILs, which is to be commended because it provides valuable insight into the origins of the behaviour of materials [4][5][6][7][8][9]. The quantitative prediction of the physicochemical properties of unknown ILs remains an important goal in research.…”

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.…”

Prediction of the thermodynamic properties of 1-alkyl-3-methylimidazolium lactate ionic liquids [C n mim][Lact] (n = 2, 3, 4, 5, and 6) by parachor

“…In recent years, there has been a developing trend in the literature towards estimation of physicochemical properties for compounds by semi-empirical methods, in particular, for ionic liquids [1][2][3][4][5]. Although the estimated results cannot be regarded as accurate physicochemical data, they do provide valuable insight into the origins of the behavior of materials.…”
