Volumetric and ultrasonic study of mixtures of 2-phenylethanol with 1-butanol, 2-butanol, and 2-methyl-1-butanol at TÂ =Â (298.15-323.15) K and atmospheric pressure: Measurement and prediction

► The density and speed of sound of some mixtures of alcohols are measured. ► The values of excess volumes over the entire composition range are negative. ► All systems under study showed non-ideal behavior. ► The TM EOS has been used to model the volumetric properties of considered mixtures. ► The agreement between the experiment and theoretical model is acceptable.
