Excess Properties of (an N-Alkoxyethanol Plus an Organic-Solvent) .6. V(M)(E)(Xch3(CH2)V-1O(CH2)2O(CH2)2Oh+(1-X)C6H5Ch3) for V=1, 2, and 4 at the Temperature 298.15-K
The excess volumes V(E) at the temperature 298.15 K for three (alkoxyethanol + toluene) mixtures have been measured over the whole mole-fraction range from densities measured with a vibrating-tube densimeter. The alkoxyethanol was 2-(2-methoxyethoxy)ethanol or 2-(2-ethoxyethyoxy)ethanol or 2-(2-butoxyethoxy)ethanol. The excess volumes curves are sigmoid with a maximum in the rich region of toluene. The excess volumes increase as the alkyl chain length of the alkoxyethanol decrease.
