Excess molar volumes of ternary mixtures {n-butylacetae + 1-butanol + 1, 2-butanediol} and {n-butylacetate + 1-butanol + 1, 3-butanediol} at T = 303.15 K

Excess molar volumes of the ternary systems formed by {n-butylacetate + 1-butanol + 1,2-butanediol } and {n-butylacetate + 1-butanol + 1,3-butanediol} were measured at 303.15 K for the whole composition range. The excess molar volumes, VmE, for binary mixtures of {n-butylacetate + 1-butanol, + 1,2-butanediol and + 1,3-butanediol} are positive and for the binary mixtures of {1-butanol + 1,2-butanediol and + 1,3-butanediol} are negative. Several empirical expressions are used to predict and correlate the ternary excess molar volumes from experimental results on the constituted binaries and analyzed to gain insight about liquid mixture interactions.
