Thermodynamic properties of the mixture [x1,3-dioxane+(1-x) 1,4-dioxane] at the temperature 298.15 K

Excess enthalpies, excess heat capacities, excess volumes and sound velocities of the mixture of dioxane isomers, 1,3-dioxane and 1,4-dioxane, were measured. One of the isomers, 1,4-dioxane is considered as non-polar liquid and the other as polar liquid. Excess enthalpies are positive and small, less than 55 J mol^-1. Excess heat capacities are also very small and the curve is W-shaped, and the values are from 0.03 to -0.08 J mol^-1 K^-1. Excess volumes and excess isentropic compressibilities are small and positive, and less than 0.03 cm³ mol^-1 and 0.8 TPa^-1.
