Apparent Molar Volumes of Water in Methanol and Tetrahydrofuran at 298.15 K

The densities of water–methanol(MeOH) and water–tetrahydrofuran(THF) mixtures have been measured at 298.15 K. The apparent molar volumes of water, Vφ,w, have been derived as a function of concentration. The values of Vφ,w in MeOH increase monotonously with the concentration, while for THF solutions...

Summary:The densities of water–methanol(MeOH) and water–tetrahydrofuran(THF) mixtures have been measured at 298.15 K. The apparent molar volumes of water, Vφ,w, have been derived as a function of concentration. The values of Vφ,w in MeOH increase monotonously with the concentration, while for THF solutions the Vφ,w curve passes through a minimum at low mole fraction of water. These are interpreted in terms of the formation of water–organic solvent and water–water hydrogen bonding.
