Fluid phase equilibria of the reacting mixture in the dimethyl carbonate synthesis from supercritical CO2 [PDF]

, 2003
In order to investigate the dimethyl carbonate synthesis from methanol and supercritical CO2, the thermodynamic behaviour of the reacting mixture, i.e. the quaternary methanol/CO2/DMC/water mixture, has to be known.

Solubility of lumiracoxib in supercritical carbon dioxide

Scientific Reports
AbstractThis study aims to use a static-based solubility method for measuring the solubility of lumiracoxib at a temperature of 308–338 K and pressure of 120–400 bar for the first time. The obtained solubility data for lumiracoxib is between 4.74 × 10−5 and 3.46 × 10−4 (mole fraction) for the studied ranges of pressure and temperature.
