Abstract:Using a continuous flow apparatus, the solubility of tridodecylamine (TDA) in supercritical CO 2 (scCO 2 ) has been measured at temperatures of (308.1, 318.1, and 328.1) K in the pressure range of (8.0 to 40.0) MPa and a flow rate of (150 ( 10) mL • min -1 . At (308.1 and 318.1) K, the solubility increases with pressure up to 15.0 MPa where it reaches a plateau. At 328.1 K, the solubility increases with pressure up to 35.0 MPa, and then a plateau is observed. The solubility data were correlated using the Bartl… Show more
“…This phenomenon is called retrograde behavior, where the density plays a dominant role as compared to the vapor pressure. 36 In other words, the operating pressures seem to be lower than the cross over pressure. 37 This can be attributed to the low vapor pressures of the compounds in the given range of temperatures.…”
Solubilities of 10-undecen-1-ol and geranyl butyrate were determined and correlated based on new models by combinations of solution/association theories.
