“…The efficacy of equations of state in predicting solubility near the critical point helps to select an appropriate equation for determining solubility. In addition to cubic equations of state, the Virial equation of state (Harvey, 1997;Schultz et al, 2010) and the SAFT equation of state (Yang and Zhong, 2005;Anvari and Pazuki, 2014) are also used to calculate solid solubility in supercritical fluids.…”

Due to the importance of supercritical fluid technology (SFT) in different industries, it has been the subject of intense research in recent decades. Solubility is a key concept in SFT. In fact, obtaining knowledge about the theoretical concepts of solubility and related experimental measurement methods can be useful in developing and improving the quality of research in this field. This study reviews the fundamental knowledge of solubility in supercritical fluids and investigates the significant topics in this field, including high-pressure phase behavior, experimental measurement methods, modeling, and molecular simulation of solubility.

“…[23][24][25][26][27][28][29] Among the models used, different classical equations of state such as the Peng-Robinson equation of state (PR-EoS), 23,26 the Soave-Redlich-Kwong equation of state (SRK-EoS), 25 the group contribution associating equation of state (GCA-EoS) 25,28 and the statistical associating fluid theory equation of state (SAFT-EoS) 29 can be found. A recent and broad revision on the different models used to predict solubility of phenolic compounds in supercritical CO 2 is available in the literature.…”

In this work, the aqueous solubilities of two hydroxybenzoic acids (gallic and salicylic acid) and three phenylpropenoic acids (trans-cinnamic, ferulic, and caffeic acids) are addressed. Measurements were performed, as a function of temperature, between 288.15 and 323.15 K, using the shake-flask method for generating the saturated aqueous solutions, followed by compositional analysis by spectrophotometric and gravimetric methods.The pH values of the saturated aqueous solutions were measured by potentiometry. Additional thermodynamic properties, which are fundamental for a better understanding of the solubilization process, as well as necessary for the modeling studies, such as melting temperatures and fusion enthalpies were determined by differential scanning calorimetry (DSC). Apparent acid dissociation constants (K a ) were obtained by potentiometry titration. The measured data were modeled with the cubic-plus-association (CPA) equation of state (EoS). This EoS is applied, for the first time, for multifunctional associating molecules, and the results indicate that it can adequately be used to represent the measured and other literature data with satisfactory accuracy.

“…Many other different types of models based on thermodynamic, molecular simulation, and solution approach have been presented by several researchers in the interest of correlating the solubilities of hazardous substances in supercritical conditions, for example, Lennard-Jones chain (PLJC) equation of state [63], solution model approach [64], simplified cluster solvation model [65], SAFT equation of state [66], Monte Carlo simulation [67][68][69][70], wavelet neural network [71] and theory of dilute solution [72].…”
