摘要：

Excess molar volumes of mixtures of n-heptane + 2,5-dioxahexane and n-heptane + 2,5,8-trioxanonane were determined from density measurements at 5, 15, 25 and 35 degrees C. These results allowed the following mixing quantities to be reported in all range of concentrations: alpha, (delta v(E)/delta T)(p) and (delta h(E)/delta P)(T), at 25 degrees C. The obtained values were then compared with the calculated values by using the Flory theory and the Nitta-Chao theory of liquid mixtures. The results are discussed in terms of order or disorder creation.
