The paper presents the results of experimental study of the solubility (VLE-properties) of crystalline tricosane in pure and modified supercritical carbon dioxide over the temperature range from (308.15 to 315.15) K and at the pressures from (8.00 to 20.32) MPa using the dynamic method. Modification of carbon dioxide fluid was performed by adding several organic solvents, such as dimethylsulfoxide, ethanol, acetone, and chloroform. It was found that using the fluid co-solvents at the concentration of 5 wt. % improves the tricosane solubility by a factor of two. The measurement results have been described by the Penga–Robinson equation of state.
