Solubility of carbon dioxide in aqueous solutions containing sodium acetate or ammonium acetate at temperatures from 313 to 433 K and pressures up to10 MPa

The solubility of carbon dioxide was measured in aqueous solutions containi ng the single salts sodium acetate and ammonium acetate corresponding to sa lt molalities in the Liquid phase of about 4 mol/kg and 6 mol/kg in the tem perature range from 313 K to 433 K at total pressures up to 10 MPa. Fitter' s semiempirical model for the excess Gibbs energy of aqueous electrolyte so lutions is used to correlate the new data. Experimental results are reporte d and compared to correlations.
