ABSTRACT

Density at 298.15 to 313.15 K and speed of sound (u) at 303.15 and 313.15 K have been measured for the binary mixtures of benzyl alcohol with chloro and nitro toluenes over the entire composition range. Experimental density and speed of sound data were used to compute excess molar volume, excess speed of sound, isentropic compressibility and excess isentropic compressibility. Further, excess properties were fitted with Redlich-Kister and Hwang equations. Finally, speed of sound data were analyzed in terms of theoretical models, Schaaff's collision factor theory (CFT) and Jacobson's free length theory (FLT).
