Abstract

In this work, two methods were developed to estimate the SOLUBILITY of Photochromic dye in supercritical CO2. First method used Soave-Redlish-Kowang (SRK) and Peng-Robinson (PR) equations of state with Huran-Vidal mixing rules while second method used semi-empirical models (recommended by Mendez and Chrastil). Since there were not any data for critical properties of Photochromic dye, a new method for evaluating of C2 (mixing rule parameter), as a function of temperature and pressure, was recommended. This function for C2 has never been reported in the literature. This method in comparison with others such as group contribution methods, predicts good result. The amounts of Average Absolute Relative Deviation (%AARD) were obtained 13.7% for SRK-EOS and 18.15% for PR-EOS. Also, a semi-empirical modified equation is used with variable coefficients which results %AARD 6.9% employing Chrastil modified model and 6.2% employing Mendez modified model.
