Solubility of dimethyl ether in pentaerythritol tetrabutyrate and in pentaerythritol tetrapentanoate. Comparison with other pentaerythritol tetraalkyl esters
The solubilities of dimethyl ether (DME) in pentaerythritol tetrabutyrate (PEC4) and in pentaerythritol tetrapentanoate (PEC5) between T = (283.15 and 353.15) K have been measured by isochoric saturation method. The experimental solubility data were correlated by the Peng Robinson equation of state with HVOS mixing rule in which the excess Gibbs free energy at infinite pressure was represented by the NRTL equation. In addition, an analysis of the influence of the molar mass on the solubility of DME in PECs over a wide range of temperature and pressure was performed.
