Excess Volumes, Speeds of Sound, and Viscosities for Mixtures of 1,2-Ethanediol and Alkoxy Alcohols with Water at 308.15 K

Abstract

Excess volume, speed of sound, and viscosity data of binary liquid mixtures of water+1,2-ethanediol,+ 2-methoxyethanol,+2-ethoxyethanol, and +2-butoxyethanol have been measured at 308.15 K. The results are used to derive densities and isentropic compressibilities. The excess volumes and deviations in the compressibility are negative while deviations in the viscosity are positive for all four systems. The results are discussed in terms of molecular interactions between like and unlike components
