Critical liquidgas-type phenomena in n-hexane in the presence of liquid phase of water

The isochoric heat capacity of n-hexane water system is studied using the adiabatic calorimeter in the range of water mole fraction between 0.256 and 0.935 at 300600 K in a wide range of densities. The obtained experimental critical curves of liquid vapor phase equilibrium are described by an equation that corresponds to the theory of critical phenomena.

Key words: isochoric heat capacity, adiabatic calorimeter, phase transition, watern-hexane system
