“…For 1,4-dioxane (2) + carbon tetrachloride (3) the maximum is -250 J mol -1 at x 2 ) 0.5098, and for butylamine (1) + carbon tetrachloride (3) it is -4616 J mol -1 at x 1 ) 0.7762. These large values of H E in this system indicate specific interactions, which is corroborated by the negative values of excess molar volumes (Acevedo et al, 1988). This implies a possible complex formation between both chemical species.…”

The excess molar enthalpies of butylamine + diethyl ether, +dipropyl ether, +bis(1-methylethyl) ether, +dibutyl ether, +1,1-dimethylethyl methyl ether, +1,1-dimethylpropyl methyl ether, +tetrahydrofuran, +tetrahydropyran, and +1,4-dioxane have been measured over the whole composition range at 298.15 K in order to investigate interactions between butylamine and the three classes of ethers, namely straight chain, branched chain, and cyclic. All the mixtures show endothermic behavior. The results reported here are compared to results for related systems involving dibutylamine published recently by our group. The experimental results have been correlated using the NRTL and UNIQUAC equations.

“…[1][2][3][4][5] A few studies involving binary amine/alcohol systems have been carried out by some other authors. [6][7][8] As part of our program of research on thermodynamic, acoustic, and transport properties of binary mixtures containing branched ethers, we have recently reported excess molar volumes, viscosities, and speed of sound measurements of binary mixtures of branched ethers with water and alcohols.…”

Excess Molar Volumes and Viscosities for Binary Mixtures of 2-Propoxyethanol and of 2-Isopropoxyethanol with Propylamine and Dipropylamine at (298.15, 308.15, and 318.15) K

Excess molar volumes V m E and viscosities η have been measured as a function of composition for the binary mixtures of 2-propoxyethanol and of 2-isopropoxyethanol with propylamine and dipropylamine at (298.15, 308.15, and 318.15) K. From the experimental data, the deviation in the viscosity η from ∑x i ln η i has been calculated at various temperatures. The excess molar volumes are negative whereas the deviation in the viscosities is positive for all investigated systems over the whole composition range. These results suggest that the stronger hydrogen bonds between unlike molecules reduce the volume of the solution and make the solution high viscosity. A Redlich-Kister type equation was applied to fit the excess volumes and viscosity deviations, and McAllister's three-body and four-body interaction models were also used to correlate the kinematic viscosities.
