Abstract

TEJRAJ M. AMINABHAVI, SHRIKANT S. JOSHI, RAMACHANDRA H. BALUNDGI, and SHYAM S. SHUKLA. Can. J. Chem. 69, 1028 (1991).Densities and viscosities of ten binary and four ternary mixtures containing bromoform, bromobenzene, chlorobenzene, toluene, mesitylene, and dimethylformamide at 25°C have been measured over the whole range of mixture compositions. Excess molar volumes, apparent values of excess molar viscosities, and Gibbs energy of activation of flow have been calculated for these mixtures. The calculated results have been fitted to a linear regression equation to estimate the parameters and the standard deviation between the calculated and the experimental data.

Ultrasonic study on binary mixture containing dimethylformamide and methanol over the entire miscibility range (0<x<1) at temperatures 303–323K

“…This may be qualitatively interpreted in terms of closer approach of unlike molecules leading to reductions in compressibility and volume [40,42]. This type of interactions for the binary mixture DMF-toluene [47], DMF-water [48] has been already reported. The pronounced compressibility minimum at x = 0.2 may be attributed to strong molecular interaction which eventually results in complexation [48].…”

Volumetric, Viscometric and Excess Properties of Binary Mixtures of 1-Iodobutane with Benzene, Toluene, o-Xylene, m-Xylene, p-Xylene, and Mesitylene at Temperatures from 303.15 to 313.15 K

“…Negative values of Δ throughout the whole composition range and at all temperatures suggest that the intermolecular interaction becomes weaker on mixing of components, also indicating that the dispersion type [17] of forces is predominant in these mixtures. The negative Δ values support the positive values and account for dispersive forces in these binaries.…”

Densities and excess volumes of binary mixtures of N,N-dimethylformamide with aromatic hydrocarbon at different temperature

“…A series of systematic investigations have been carried out on the excess molar volume ðV E m Þ of different binary mixtures of DMF with single aromatic hydrocarbon by different scientists using different methods [1][2][3][4][5][6][7][8][9][10] at the range of temperature 298.15 K to 313.15 K. Results of these experiments are quite different from each other. Some authors only reported V E m , did not report the density q.…”
