Critical «liquid—gas»-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 300—600 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, «water—n-hexane» system
