摘要：

Excess molar volumes were determined over the whole composition range for (dimethyl carbonate, or diethyl carbonate + n-heptane) at the temperatures (278.15, 288.15, 298.15, and 308.15) K, and at atmospheric pressure with a vibrating-tube densimeter. In addition, a differential scanning calorimeter was used to obtain excess isobaric molar heat capacities for the same mixtures at the temperatures (288.15, 298.15, and 308.15) K, and at atmospheric pressure. The influence of the upper critical solution temperature on the measured properties is also discussed. (C) 1999 Academic Press.
