Density, viscosity and speed of sound of binary liquid mixtures of butyl propionate with tetrahydrofuran, 1,4-dioxane, anisole and butyl
vinyl ether were measured at ( 303.15,308.15 and 313.15 ) K and over the entire composition range. From the experimental data values
of excess volume V
E
, viscosity deviations ∆η, deviation in speeds of sound ∆u, isentropic compressibility Ks and deviation in isentropic
compressibility ∆KS, have been determined. The speeds of sound data have been analysed on the basis of Jouyban–Acree and Vandeal–
Vangeel models.
Key words: density, viscosity, speed of sound, binary mixture, n-butyl propionate
