An automated static total pressure measurement apparatus was used to measure isothermal vaporliquid equilibria for five binary systems: trans-2-butene + methanol, + ethanol, + 2-propanol, + 2-butanol, and + 2-methyl-2-propanol at 332.3 K. Error analysis of the measured results has been presented. All systems exhibited positive deviation from Raoult’s law. The trans-2-butene + methanol and …
The equilibrium solubility of aspirin in supercritical CO2 has been determined using a dynamic method. Measurements were performed at pressures ranging from (10 to 25) MPa and temperatures from (308.15 to 328.15) K. The effect of a polar cosolvent, acetone, on the solubility of aspirin in supercritical carbon dioxide was also studied. The results show that the addition of acetone produces up…
