The solubility of ammonia in ethylene glycol is measured by an isothermal solubility equilibrium method at temperatures of(303.2,308.2,313.2,318.2 and 323.2)K and total pressures of(0.030,0.040,0.050,0.060,0.070,0.080,0.090 and 0.101)MPa.The molality of ammonia in ethylene glycol ranges from 1.925 mol·kg?1 to8.265 mol·kg?1.The experimental results are used to determine Henry’s law constant of ammonia in ethylene glycol.Furthermore,experimental data are correlated by applying the thermodynamic model on the basis of extended Raoult’s law,extended Henry’s law,corresponding-states correlations and Pitzer’s molality scale based equation.The overall average relative deviation between the calculated data and the experimental data of Henry’s law constant and ammonia solubility are 2.029%and 2.164%respectively. The solubility of ammonia in ethylene glycol is measured by an isothermal solubility equilibrium method at temperatures of (303.2,308.2,313.2,318.2 and 323.2) K and total pressures of (0.030,0.040,0.050,0.060,0.070,0.080,0.090 and 0.101 ) MPa. The molality of ammonia in ethylene glycol ranges from 1.925 mol · kg -1 to 8.265 mol · kg -1 1. The experimental results are used to determine Henry’s law constant of ammonia in ethylene glycol. Futurerther, experimental data are correlated by applied the thermodynamic model on the basis of extended Raoult’s law, extended Henry’s law, corresponding-states correlations and Pitzer’s molality scale based on the overall average relative deviation between the calculated data and the experimental data of Henry’s law constant and ammonia solubility are 2.029% and 2.164% respectively.
