Quasi-static measurement of equilibrium solubilities in SC fluids: a mass transfer criterion

Solubilities of cinnamic acid, phenoxyacetic acid and 4-methoxyphenylacetic acid in supercritical carbon dioxide

“…The experimental solubility data in supercritical CO 2 have been examined by applying a fluid-solid mass transfer model [9]. The detail procedures have been presented in our previous work [5].…”

Solubilities of N-phenylacetamide, 2-methyl-N-phenylacetamide and 4-methyl-N-phenylacetamide in supercritical carbon dioxide

“…A fluid-solid mass transfer model presented by Abaroudi et al [8] was solved in this study under our experimental conditions. The purpose of solving this model was to ensure that the mass transfer effects were insignificant to our measurements.…”

“…In this study, we therefore report novel data for further applications and modeling. A fluid-solid mass transfer model investigated by Abaroudi et al [8] was applied under our experimental conditions. It was used to examine whether the measured solid concentration in the fluid at the exit of the experimental cell approached the equilibrium solubility.…”

Solvent Screening for the Supercritical Hydrogenation of Polyunsaturated Hydrocarbons Using VLE Calculations

“…To measure the solubilities of the reactant (CDT) and the second intermediate (CDE) in supercritical CO 2 , quasi-static-equilibrium runs at very low CO 2 flow rates were carried out at pressures, temperatures, and flow rates of 200−250 bar, 380−423 K, and 0.1−0.3 L/min, respectively. This method has already provided good results in the cases of the binary and ternary systems toluene−CO 2 , benzene−CO 2 , and ethylbenzene−CO 2 9 and α-naphthol−CO 2 , β-naphthol−CO 2 , and β-naphthol−CO 2 −toluene. , For the runs, porous steel cylinders ( h = 0.8 cm, d = 0.8 cm) were impregnated overnight with either CDT or CDE and were then placed into a preheated steel extractor cell ( h = 5 cm, d = 2.1 cm). The temperature was monitored by J-type thermocouples.…”
