Abstract:
Experimental results on equilibrium pressure over KOH + NH3 + H2O solutions are reported. The temperature was varied between -6 and +30 °C, while the molalities of NH3 and KOH were varied in the range 1-12 and 1-10 mol·kg-1, respectively. An analytical equation of the equilibrium pressure as a function of temperature and concentrations was obtained. The partial molar enthalpy of solution of ammonia in the KOH + H2O mixtures and the Henry coefficients for ammonia were also calculated. For the ternary mixture the Setschenow relation was considered and validated in the range of measured concentrations.
