Thermodynamic properties of n-alkoxyethanols+organic solvent mixtures: XVIII. Excess volumes at 298.15 K for 2-(2-alkoxyethoxy)ethanol+n-polyether

Excess molar volumes, VE at 298.15 K and atmospheric pressure for 2-(2-methoxyethoxy)ethanol or 2-(2-butoxyethoxy)ethanol+2,5-dioxahexane, +2,5,8-trioxanonane, +3,6,9-trioxaundecane, +5,8,11-trioxapentadecane, and +2,5,8,11,14-pentaoxapentadecane, or for 2-(2-ethoxyethoxy)ethanol+2,5,8-trioxanonane, +3,6,9-trioxaundecane, and +5,8,11-pentaoxapentadecane have been obtained from densities measured with and Anton-Paar DMA 602 vibrating-tube densimeter. The VE values are usually negative indicating that interactions between unlike molecules are predominant over other effects. The investigated mixtures behave similar to those with 2-methoxyethanol, 2-ethoxyethanol or 2-butoxyethanol and the same oxaalkanes.
