文摘
- •
Densities, ultrasonic speeds and refractive indices of phenetole + NMP, DMF and THF binary mixtures were evaluated.
- •
Excess molar volumes, isentropic compressibilities, refractive indices and ultrasonic speed deviation of these mixtures were calculated.
- •
The ultrasonic speeds were analyzed in term of CFT, FLT, NR and IMR.
- •
Excess and deviation properties were fitted to Redlich-Kister least square method.
- •
The results were interpreted on possible molecular interactions between components as well as the effect of polarity.
