Phase Equilibrium and Critical Properties of the System [xH2О + (1 – x)C7H16], x = 0.355

Phase Equilibrium and Critical Properties of the System [xH2О + (1 – x)C7H16], x = 0.355 An automated, experimental setup based on a high-temperature, adiabatic calorimeter-piezometer was used to study the temperature dependence of the isochoric-heat capacity of a double stratified system of n-heptane–water with a water content of x = 0.355 (mole fraction) in a density range of 149.9–399.8 kg/m3 at temperatures of 397.15–550.15 K. This includes the phase-transition regions and the critical region. The critical system parameters and the parameters of azeotrope formation are determined. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png High Temperature Springer Journals

Abstract

An automated, experimental setup based on a high-temperature, adiabatic calorimeter-piezometer was used to study the temperature dependence of the isochoric-heat capacity of a double stratified system of n-heptane–water with a water content of x = 0.355 (mole fraction) in a density range of 149.9–399.8 kg/m3 at temperatures of 397.15–550.15 K. This includes the phase-transition regions and the critical region. The critical system parameters and the parameters of azeotrope formation are determined.
