Solubility of Polycyclic Aromatic Hydrocarbons in Supercritical Carbon Dioxide

Abstract

The equilibrium solubilities of three solid polycyclic aromatic hydrocarbons (acenaphthene, fluoranthene, and triphenylene) were determined at temperatures ranging from 308 K to 348 K and pressures from 121.6 to 354.6 bar in supercritical CO 2 . The data were obtained by using a simple static sampling apparatus which was tested by measuring the solubility of naphthalene in compressed CO 2 . The measured solubilities were correlated using a semiempirical model. The calculated results show satisfactory agreement with the experimental data.

Investigations on the solubilities of some disperse azo dyes in supercritical carbon dioxide

“…A detailed description of the construction and calibration of this method has been previously reported [7,8]. Briefly, a 1-ml high-pressure saturation cell was filled with a 10 mass% mixture of compound with clean glass beads to prevent channeling.…”

A New Simple Equation of State for Calculating Solubility of Solids in Supercritical Carbon Dioxide

“…In [10,[20][21][22][23][24][25][26][27][28]. To reproduce the solid solubility in supercritical carbon dioxide, the Peng Robinson equation of state (PR EOS) has been applied in combination with the van der Waals (vdW1) and Wong Sandler (WS) mixing rules.…”

Decontamination of hazardous substances from solid matrices and liquids using supercritical fluids extraction: A review

“…The solubility of solids and liquids in supercritical fluids needs careful consideration in the development of any supercritical extraction process. In the litera- [52] ture, solubility measurements for numerous hazardous solutes in a number of supercritical fluids have been reported [37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52]. The list of solubility studies for several hazardous compounds is condensed in Table 3.…”

“…(6), results physically from solvation of the solute by the supercritical fluid, is assumed to remain constant. This semi-empirical equation has been applied to predict the solubility of hazardous compounds in supercritical fluid by Yamini and Bahramifar [38], Yamini et al [39], and Miller et al [42].…”
