Enhancement of Solubility of Troeger's Base in Supercritical Carbon Dioxide by Methanol

摘要

The solubility of Troeger’s base （TB） in SC-C2/CH3OH was measured at 308K in the pressure range of 8 to 13 MPa. and methanol concentration ranges from 0 to 20 mol%. The solubility increases dramatically with methanol concentration. Comparison of solubility in supercritical CO2 with and without 10 mol% CH3,OH in the prcssure of 8 MPa at 308K implies that both curves are steep in the lower pressure range but become smooth as the pressure increases.
