Abstrakty
The ultrasound velocities in and densities of mixtures of 3-methylpyrazol with cyclohexa and in the pure components were measured at temperaturę 293.15 K. The absorption of ultrasound was measured at 293.2 K in 11 mixtures of 3-methylpyrazol with cyclohexane within the k 3-methylpyrazol concentrations range. For the investigated solutions and pure components the quotient alfa/f2 is independent frequency within the tested frequency range (10 - 80 MHz). The dependencies of the mean vlues of alfa/f2 on mixture composition show maximum at low 3-methylpyrazol concentrations to (x1 almost equal to 0.13) while the ultrasound. velocity decreases monotonically with increasing mole fractions 3-methylpyrazol up to x1 almost equal to 0.3. The dependencies of ultrasound absorption and velocities on the mixture composition were compared and discussed in terms of the entropy effect connected w solvate destruction during dimerization and other factors affecting the specific self-association 3-methylpyrazol in cyclohexane.
