Using a continuous flow apparatus, the solubility of trioctylamine (TOA) in supercritical CO2 (scCO2), have been measured at temperatures of 308.15, 313.15, 318.15, 328.15, and 338.15 K in the pressure range of 80–400 bar and flow rate of 120 ± 10 mL min−1. At 308.15 and 313.15 K, the solubility increases with pressure up to 125 bar where it reaches a plateau. At 318.15 K the solubility increases with pressure up to 250 bar and then a plateau is observed, but solubility of TOA in scCO2 at 328.15 and 338.15 K increased with pressure almost linearly until 400 bar and no plateau is observed. The solubility data were correlated using Bartle, Chrastil, and Mendez-Santiago and Teja equations. TOA may be considered as a highly soluble compound in scCO2.
