Experimental Study on the Solubility of Fluorene in Different Solvents

Abstract

The solubilities of fluorene in Exxsol D30, Exxsol D40, and crude dimethyl ethylbenzene (DME) from 299.25 to 356.85 K were investigated using the gas chromatography (GC) observation technique. Solubility curves were obtained based on the results and correlated with the modified Apelblat and λh equations to provide a valid model to predict the dissolution thermodynamic properties of fluorene at different temperatures, which is important in separating fluorene by crystallization.
