文摘

Densities and viscosities for binary mixtures of 4-methylbenzene-1,3-diamine and 2-methylbenzene-1,3-diamine in solvents of water, ethanol, propan-1-ol, and butan-1-ol were measured at T = (293.15, 303.15, 313.15, 323.15, and 333.15) K under atmospheric pressure. The measured densities and viscosities of the studied systems were correlated by the Guimar茫es鈥檚 equation and the extended Jones-Dole equation, respectively. Apparent molar volumes (V_蠁) and the activation energies of viscous flow (E_a) were calculated by experimental results, and V_蠁 was correlated by a linear equation to obtain the limiting apparent molar volumes at infinite dilutions (V_蠁⁰) and experimental slope (S_V). The V_蠁, V_蠁⁰, and S_V values have been qualitatively used to interpret the solute鈥搒olvent and solute鈥搒olute interactions via hydrogen bond and hydrophobic hydration interactions between component molecules, which origins from the structural factors.
