Abstract: The molar execess enthalpies of C_1 to C_5 normal alcohols with 1,4-dioxane have been measured with a Picker flow microcalorimeter. From our measurements we can come to the following results. Mixing n-alcohols with 1,4-dioxane are all endothermic processes. The maximum values of H~E are situated near 0.49 mole fraction of n-alcohols. H~E of these systems increase with increasing chain length of the alcohols, whereas the increments for two neighbour-alcohols decrease with increasing the number of carbon.
