“…A departure from linearity in the ultrasonic velocity versus composition behavior in liquid mixtures is an indication of the existence of interaction between different species 13 . Various theories which were originally proposed for binary mixtures 14 Ramasamy and Anbananthan 15 carried out the ultrasonic investigations on some binary and ternary liquid mixtures and correlated the experimental findings of ultrasonic velocity with the theoretical relations suggested by Nomoto 16 and Van Deal and Van Geel 17,18 and interpreted the results in terms of molecular interactions.…”

Ultrasonic velocities and densities of the binary liquid mixtures of benzene with 1-propanol, 2-propanol, 1-butanol, 2-butanol and 3-butanol at 303.15 to 318.15 K, over the entire composition range were measured. The theoretical values of ultrasonic velocity were evaluated using the Nomoto's Relation (NR), Ideal Mixture Relation (IMR), Free Length Theory (FLT) and Collision Factor Theory (CFT). The validity of these relations and theories were tested by comparing the computed sound velocities with experimental values. Further, the molecular interaction parameter (α) was computed by using the experimental and the theoretical ultrasonic velocity values. The variation of this parameter with composition of the mixtures has been discussed in terms of molecular interaction in these mixtures.

Se informan en este trabajo las densidades (ρ) y las velocidades del sonido (u) de las mezclas líquidas binarias formadas por propanonitrilo + propanoato de metilo y propanonitrilo + propanoato de etilo, incluidas las de los líquidos puros, en un rango de temperatura de 278.15 K a 318.15 K a intervalos de 5 K. La densidad y la velocidad del sonido se midieron en todo el rango de composición a la presión atmosférica. Los datos experimentales se utilizaron para calcular el volumen molar V(x, T), el volumen molar de exceso VE(x, T), la desviación en la velocidad del sonido Δu(x, T), la compresibilidad isoentrópica Ks(x, T), la compresibilidad isoentrópica de exceso E KS (x, T), el coeficiente de expansión térmica α(x, T) y el coeficiente de expansión térmica de exceso αE(x, T). Cada conjunto de resultados de las propiedades de exceso se ajustó a una ecuación polinómial como la ecuación de Redlich-Kister [1], obteniéndose desviaciones del orden de error experimental. Los valores de exceso de las mezclas estudiadas fueron negativos para todo el rango de composición y para todas las temperaturas. Los resultados se discutieron en términos de las interacciones moleculares y los efectos estructurales. Se utilizaron los modelos propuestos por Nomoto [2,3], Van Dael [4] y Ernst et al. [5] para calcular la velocidad del sonido a 298.15 K.
