The solubility of Troeger's base (TB) in SC-CO₂/CH₃OH was measured at 308K in the pressure range of 8 to 13 MPa, and methanol concentration ranges from 0 to 20 mol%.The sohubility increases dranmatically with methanol concentration.Comparison of solubility in supcrcritical CO₂ with and without 10 mol% CH₃OH in the prcssure of 8 MPa at 308K implies that both curves are steep in the lowcr pressure range but become smooth as the pressure increases.
