Measurement and correlation of solubility of Disperse Blue 14 in supercritical carbon dioxide

Solubility of caffeine from green tea in supercritical CO2: a theoretical and empirical approach

“…Computation of the solubility estimation is simpler using empirical correlations based on density models such as Chrastil, Gordillo, Yu, Jouyban and Mendez-Santiago-Teja as listed in 2.01 8.14 1.69 Table 2 (Chrastil 1982;Gordillo et al 2003;Jouyban et al 2002a;Mendez-Santiago and Teja 2000;Yu et al 1994). Coefficients for the empirical models along with respective AARD values are presented in Table 5.…”

Particles Formation Using Supercritical Fluids

“…For instance, in the facilities of University of Cádiz, the solubility of solid dyes like 1,4-dimethylaminoanthraquinone (Disperse Blue 14) in supercritical carbon dioxide has been determined in the pressure range of 100-350 bar and in the temperature range of 313-353 K and correlated with empirical and semi empirical equations based model and models based on thermodynamic aspects and the use of equations of state (Gordillo et al, 2003). The solubility of palmitic acid in supercritical carbon dioxide was determined experimentally in the pressure range, 100 to 350 bar, and the temperature range, 308 to 323 K. A cubic equation of state and an empirical equation were used to correlate the solubility of this fatty acid in supercritical carbon dioxide (Gordillo et al, 2004).…”

Solubilities in supercritical fluids

“…There are also severe numerical complexities in the neighborhood of mixture critical points and critical end points. All of these are areas of active research [158][159][160][161][162][163][164][165][166][167][168][169][170].…”
