Speed of sound, isentropic compressibility and acoustic impedance for long chain non-polar molecule with isomeric alcohols at T=288.15 to 318.15 K

Abstract

Theoretical results for sound speed, isentropic compressibility, and acoustic impedance for two binary systems, 1-Butanol + n-Dodecane and 2- Butanol + n-Dodecane, were derived from Peleteiro et al's measurements at temperatures of 288.15, 298.15, 308.15,318.15 K and atmospheric pressure over the entire composition range. The mixing properties and interactions of these liquids were explored using the Flory model, the Ramaswamy and Anbananthan (RS) model, and the Glinski model. The Redlich-Kister polynomial equation was used to fit deviations in the speed of sound (u). In addition, the McAllister multi- body interaction model is applied. The molecular interactions from these liquid state models were explored and connected with the features of the liquids. Finally, it was discovered that when compared to related models, the McAllister multibody interaction model (non- associated) produces good results, whereas the Flory model produces greater deviations.
