Experimental data are reported at 298.15 K of excess molar volumes V E and excess molar enthalpies H E for two ternary mixtures of 1-butanol + (butyl vinyl ether or isobutyl vinyl ether) + heptane. The results are explained in terms of the influence of the n-alkane on cross-association between an alkanol and an ether. A vibrating-tube densitometer was used to determine V E. H E was measured using a quasi-isothermal flow calorimeter. The experimental results are used to test the applicability of the ERAS model for describing thermodynamic excess properties of ternary mixtures containing an alkanol, an ether, and an alkane.
