Excess parameter studies on the binary mixtures of toluene with ketones at different temperatures

Determination of thermodynamic properties for protonation equilibrium between isomeric cresols and N,N-dimethylaniline in n-hexane medium

“…From the measured values of ultrasonic velocity (u), density (ρ) and viscosity (η), various acoustical and excess thermo acoustical parameters were computed using the following standard formulae [23][24][25]. Isentropic compressibility (κ s ) value can be calculated using Eq.…”

Temperature dependence of isentropic compressibilities for the ternary mixture Acetone + Methanol + n-Hexane

“…nº 20,860-4 or 20,858-2, respectively) to remove trace amounts of water. The ultrasonic velocity measured experimentally for each component was compared with literature values in Table 1 [20][21][22][23][24][25][26][27][28][29][30]. Precautions were taken, such as cooling chemicals to reduce vapour pressure, before the samples preparation.…”
