اندازه گيري و مدل سازي حلاليت كربن دي اكسيد در مخلوط دو تايي از چهار حلال

In this research the solubility of carbon dioxide in the mixtures of organic solvents in the temperature range of 10-25ʹC and atmospheric pressure was measured. The effect of temperature and solvent mixture concentrations on solubility was studied and an empirical relationship was presented. /I A.() the Henryʹs constant for carbon dioxide in the mixture of organic solvents base on the Henryʹs constant in pure solvents was obtained. In addition, the theoretical solubility of carbon dioxide was calculated by using of thermodynamic models such as regular solution model, Margulus and Wilson moldeL The regular solution model for prediction of carbon dioxide solubility was also expanded.
