Using a continuous flow apparatus, the solubility of tridodecylamine (TDA) in supercritical CO2 (scCO2) 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 Bartle equation and the Mendez-Santiago and Teja model. The Mendez-Santiago and Teja model correlated the solubility data better than the Bartle equation. TDA may be considered as a highly soluble compound in scCO2.
