Thermodynamic investigations of ternary o-toluidine+tetrahydropyran+N,N-dimethylformamide mixture and its binaries at 298.15, 303.15 and 308.15K

Topological investigations of binary mixtures containing ionic liquid 1-ethyl-3-methylimidazolium tetrafluoroborate and pyridine or isomeric picolines

“…For the studied mixtures, it is reasonable to assume that v ij ffi v jj ¼ v = ij equation (13) can therefore be expressed by…”

“…1-Ethyl-3-methylimidazolium tetrafluoroborate is one of the latest investigated ionic liquid and thermodynamic data of mixtures relating to this ionic liquid is scarce [8][9][10][11]. In recent studies [12][13][14][15] Graph theory has been employed successfully to predict excess molar volumes, V E , excess molar enthalpies, H E , excess isentropic compressibilities, j E S and excess Gibb's free energy, G E data of the various binary as well as ternary mixtures comprising of organic solvents. It would be of interest to see how Graph theory describes the V E , H E , and j E S values of the investigated binary ionic liquid mixtures.…”

Thermodynamic and theoretical study on hydrogen bonded binary mixtures of isomeric butanols with o-toluidine at T=(303.15 to 318.15) K

“…The mass fraction purities were tested by gas chromatography and are given in Table 1. The purity of the solvents is ascertained by comparing the experimental values of density, viscosity and speed of sound with those reported in the literature at T = (303.15 to 318.15) K with the literature [20][21][22][23] (shown in Table 2). …”

Excess molar enthalpies of binary and ternary liquid mixtures

“…The uncertainties in the density and speed of sound measurements are ±0.5 kg m -3 and 0.1 m s -1 , respectively. Further, uncertainty in the temperature measurement is ±0.01 K. The q and u values for the purified liquids at 298.15 K are listed in Table 2 and are also compared with literature values [16,[20][21][22][23][24][25][26][27][28].…”
