Abstract
Densities and viscosities of naphthalen-1-ol, naphthalen-2-ol, and 1-aminonaphthalene in solvents of 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. Guimaraes's equation and the extended Jones–Dole equation were utilized to correlate the densities and viscosities of naphthalen-1-ol, naphthalen-2-ol, and 1-aminonaphthalene alcoholic solutions, respectively. The apparent molar volumes were calculated at T = (293.15, 303.15, 313.15, 323.15, and 333.15) K using experimental densities. Limiting apparent molar volumes were analyzed and discussed in terms of solute–solvent and solute–solute interactions. The dependence of the viscosity on temperature could be well-explained by the Arrhenius type equation involving viscous flow activation energies that always increase with solute concentration for a given solvent.
