Abstract
The solubility of ethane in N-methylpyrrolidinone (NMP) has been measured at −10, 25, 40, 50, 70, 75, 100, and 120°C at pressures up to 7.1 MPa. The solubility data obtained are compared with those of ethane in other physical solvents. The results were correlated with the Peng-Robinson (1976) equation of state and the interaction parameters were obtained. Henry's constants were also determined.
On a mesuré la solubilité de l'éthane dans du N-méthylpyrrolidinone à des températures de −10, 25, 40, 50, 70, 75, 100 et 120°C et à des pressions allant jusqu'à 7,1 MPa. Les données de solubilité sont comparées avec la solubilité dans d'autres solvents physiques. Les données de solubilité ont été corrélées à l'aide de l'équation d'état de Peng-Robinson (1976) et les paramètres d'interactions ont été obtenus. On a aussi calculé les valeurs des constantes de la loi d'Henry.
