Solubility of CO2 in aqueous solutions of methionine and in aqueous solutions of (K2CO3 and methionine) / Jacek Kumełan in Industrial & engineering chemistry research, Vol. 49 N° 8 (Avril 2010)  

Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 49 N° 8 (Avril 2010) . - pp. 3910–3918 Titre : Solubility of CO2 in aqueous solutions of methionine and in aqueous solutions of (K2CO3 and methionine) Type de document : texte imprimé Auteurs : Jacek Kumełan, Auteur ; Álvaro Pérez-Salado Kamps, Auteur ; Maurer, Gerd, Auteur Année de publication : 2010 Article en page(s) : pp. 3910–3918 Note générale : Industrial Chemistry Langues : Anglais (eng) Mots-clés : Aqueous Solutions Methionine Résumé : The influence of the amino acid d,l-methionine on the solubility of carbon dioxide in pure water and in aqueous solutions of potassium carbonate was investigated. The solubility was measured with a high-pressure view-cell technique operating on the synthetic method. Temperature and total pressure ranged from about 353 to 393 K and 1 to 10 MPa, respectively. The molality of methionine was between about 0.42 mol·(kg H2O)−1 and 0.83 mol·(kg H2O)−1. The molality of potassium carbonate was about 1.25 and 2.5 mol·(kg H2O)−1. The solubility of carbon dioxide in aqueous solutions of potassium carbonate and methionine is influenced by chemical reactions: On one side, dissolving carbon dioxide in an aqueous solution of potassium carbonate shifts the chemical reaction equilibrium from carbonate to bicarbonate and, on the other side, methionine is a zwitterionic substance. The new experimental results are correlated using an extension of a previously published thermodynamic model for the solubility of carbon dioxide in aqueous solutions of potassium carbonate.
