Density, sound velocity and refractive index in the water + 1,2-dimethoxyethane system

Density, sound velocity and refractive index of binary mixtures of water + 1,2-dimethoxyethane mixtures were measured over the whole composition range and at the temperature interval from 293.15 to 323.15 K. Obtained density data for the pure components agree, within experimental error, with publish...
