Solubility of Bisphenol A in Supercritical Carbon Dioxide

Abstract

The solubility of solid bisphenol A (4,4 0 -(propane-2,2-diyl)diphenol) in supercritical carbon dioxide (SC-CO 2 ) has been measured at temperatures of T = 313 K, T = 333 K, and T = 353 K and in the pressure range 12 MPa < P < 20 MPa, using a variable-volume view cell according to the synthetic method. The solubility increases with increasing pressure and temperature, ranging from 1.8 3 10 À5 (mole fraction) at T = 313 K and P = 16.4 MPa to 7.7 3 10 À5 (mole fraction) at T = 353 K and P = 14.6 MPa. The solubility data obtained have been correlated using the PengÀRobinson equation of state with quadratic mixing rules. The results obtained are useful for the design of processes for the synthesis or recycling of polycarbonate in supercritical CO 2 .

Solubility of Solids in Sub- and Supercritical Fluids: A Review 2010–2017

“…It has been established that BPA causes neurological and behavioral effects at early stages of development and may affect the human reproductive system. 93,94 The solubility of bisphenol A in SC CO 2 was experimentally determined by Jin et al and Marti ́n et al 95,96 The experimental solubility data and the correlation model can provide fundamental knowledge for the separation process of bisphenol A using supercritical fluid technologies.…”

Production of Bisphenol A (BPA) By Green Technology

“…It can be defined as the amount of solute that dissolves in a given amount of solvent at a definite temperature to yield a solution that is saturated in nature. However, solubility is affected by several factors such as pressure, temperature, and nature of solute and solvent [13]. Many studies on solubility in supercritical fluids have grown drastically in recent years.…”

“…The fact that the properties of supercritical fluid can be varied from gas-like to liquid-like values by changing the pressure makes it very interesting and useful. In addition, solubility is the most important criterion affecting the efficacy of most of the supercritical fluid processes [13]. It has a direct impact on the rate, yield, design, and economy of the process, depending on the process of interest, high solubility or low solubility may be desired, for instance, high solubility is required to manufacture particle.…”

“…It has a direct impact on the rate, yield, design, and economy of the process, depending on the process of interest, high solubility or low solubility may be desired, for instance, high solubility is required to manufacture particle. In the case of BPA synthesis, solubility of reagents in supercritical carbon dioxide is important to accelerate the rate of reaction and enhance the reaction between acetone and phenol, thus elimination of undesired products will be achieved [13].…”
