The isochoric heat capacity of n-heptane–water mixtures

The isochoric heat capacity of mixtures of n-heptane+water with compositions of 3.0 wt.% and 11.50 wt.% of water is investigated in liquid–liquid–vapor, liquid–vapor and homogeneous states using high-temperature adiabatic calorimeter. The density of the azeotropic state was determined from the CV measurements.
