摘要

Abstract

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·kg1 to 8.265 mol·kg1. 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.
