Study on the Liquid-solid Phase Equilibrium of Anthracene and Carbazole in Some Organic Solvents

Using a phase equilibrium apparatus, the solubilities of anthracene and carbazole in dimethyformamide(DMF), N methylpyrrolidinone(NMP), cyclohexanone(CHN), xylene, dichloroethane(CED) and tetrachloroethylene(TCE) were determined and solubility curves were drawn, providing useful data for crude anthracene processing. It was found that it was more efficient for refining crude anthracene with DMF and for refining crude carbazole with TCE.
