Rutile solubility in supercritical NaAlSi3O8–H2O fluids

Solubility of Tridodecylamine in Supercritical Carbon Dioxide

Using a continuous flow apparatus, the solubility of tridodecylamine (TDA) in supercritical CO2 (scCO2), have been measured at temperatures of 308, 318, and 328 K in the pressure range of (8-40) MPa and a flow rate of 150 ± 10 mL min. At 308 and 318 K the solubility increases with pressure up to 15 MPa where it reaches a plateau. At 328 K the solubility increases with pressure up to 35 MPa and ...

Frenkel line and solubility maximum in supercritical fluids.

A new dynamic line, the Frenkel line, has recently been proposed to separate the supercritical state into rigid-liquid and nonrigid gaslike fluid. The location of the Frenkel line on the phase diagram is unknown for real fluids. Here we map the Frenkel line for three important systems: CO(2), H(2)O, and CH(4). This provides an important demarcation on the phase diagram of these systems, the dem...

Solubility Parameter of Fluids from Molecular Thermodynamic Model

The modified square well Potential is combined with perturbed-hard-trimer-chain (PHTC) EOS to predict the solubility parameter of several fluids including alkanes, refrigerants and molten polymers. The performance of the proposed model has been evaluated by predicting the solubility parameter of 12 hydrocarbons,3 refrigerants, and 12 polymers. From the 263 data points for hydrocarbons and refri...

Measurement and Modeling of Acridine Solubility in Supercritical Carbon Dioxide

Supercritical carbon dioxide has gained increasing attention in food and pharmaceutical processing owing to the fact that it is environmentally inexpensive, not flammable, essentially non-toxic, and it has a convenient critical point. Also, it has been attracting much attention in many fields, such as extraction of sensitive materials and pharmaceutical processing and polymerization processes. ...
