Solubility of Diflunisal in Supercritical Carbon Dioxide [PDF]

Journal of Chemical & Engineering Data, 2008
The solubility of diflunisal, a nonsteroidal anti-inflammatory drug (NSAID), in supercritical carbon dioxide (scCO2) was measured at (308.2, 318.2, and 328.2) K and in the pressure range from (9.0 up to 25.0) MPa. Results were obtained using a static analytical method. Experimental solubility was found to be between 0.54·10−6 and 8.07·10−6 (in terms of

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.
