Excess molar enthalpies of 1,3-dioxolane,or 1,4-dioxane with isomeric butanols

Gascon I, Artigas H, Martin S, Cea P, Lafuente C

Using a flow-mixing calorimeter, excess molar enthalpies of 1,3-dioxolane, or 1,4-dioxane, with isomeric butanols were determined at the temperatures of 298.15 K and 313.15 K. All the studied systems show positive excess molar enthalpies. The results are compared with calculated values from the UNIFAC model.
