Excess volumes of the ternary mixtures butylamine–cyclohexane–benzene and Tributylamine–cyclohexane–benzene
Journal of the Chemical Society Faraday Transactions, 1994Co-Authors: S. L. Oswal, S.g. PatelAbstract:Excess volumes of the ternary mixtures butylamine–cyclohexane–benzene and Tributylamine–cyclohexane–benzene at 298.15, 303.15 and 313.15 K have been investigated from density measurements using a vibrating densitometer. A number of empirical equations predicting ternary mixture properties from the composite binary parameters have been examined. Furthermore, the Prigogine–Flory–Patterson theory has been extended for ternary mixtures and is applied to the present ternary mixtures.

excess volumes of binary mixtures of triethylamine and Tributylamine with alkanes and alkylamines at 298 15 303 15 and 313 15 k
Journal of the Chemical Society Faraday Transactions, 1992Co-Authors: S.g. Patel, S. L. OswalAbstract:Excess volumes (VE) and their temperature dependence (dVE/dT) have been investigated from density measurements, using a vibrating densitometer DMA 60/602, for binary mixtures of triethylamine and Tributylamine with hexane, octane, iso-octane (2,2,4-trimethylpentane), propylamine, butylamine, hexylamine and octylamine, and of Tributylamine with decylamine and dodecylamine. Thermal expansion coefficients α and excess thermal expansion coefficients αE were evaluated from the results. The Prigogine–Flory–Patterson theory has been applied to estimate interaction, free volume and internal pressure contributions to VE and to estimate dVE/dT for the mixtures.

density viscosity refractive index and speed of sound in the binary mixtures of 1 4 dioxane ethanediol hexane Tributylamine or triethylamine at 298 15 303 15 and 308 15 k
Journal of Chemical & Engineering Data, 2003Co-Authors: Jyoti N Nayak, Mrityunjaya I Aralaguppi, Tejraj M AminabhaviAbstract:Densities, viscosities, and refractive indices of the binary mixtures of 1,4-dioxane with ethanediol, hexane, Tributylamine, and triethylamine have been measured at (298.15, 303.15, and 308.15) K, while the speed of sound data are measured at 298.15 K. From these results, excess molar volume and deviations in viscosity, molar refraction, speed of sound, and isentropic compressibility have been calculated. These results are fitted to the polynomial equation to derive the binary coefficients. Standard errors have been calculated between the fitted results and the calculated data. These data have been used to discuss the mixing behavior of the components.

Russian Journal of Coordination Chemistry, 2003Co-Authors: O. A. Petrov, S. A. Lysova, B. D. Berezin, N. V. ChizhovaAbstract:Kinetics of complexation between magnesium acetylacetonate and tetraazaporphine in benzene–pyridine (2-methylpyridine) system is studied. The rate and activation parameters of the process were found to be determined by the addition of these bases. A possible mechanism of the Mg complex formation is discussed. No magnesium complex with tetraazaporphine was formed in benzene–morpholine (benzylamine, n -butyl-amine, diethylamine, triethylamine, Tributylamine) system.
