摘要：

The excess molar volume at 298.15 K and atmospheric pressure for three (alkoxyethanol + toluene) mixtures have been determined over the whole mole fraction range from densities measured with a vibrating-tube densimeter. The alkoxyethanols were 2-methoxyethanol, 2-ethoxyethanol and 2-butoxyethanol. The three excess volumes curves have a maximum in the toluene rich region and those with 2-ethoxyethanol and 2-butoxyethanol are sigmoidal. The excess molar volumes increase as the alkyl chain length of the alkoxyethanol decreases.
