蒽和咔唑在若干有机溶剂中的液固相平衡研究

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

利用液固相平衡实验装置，测定了蒽和咔唑在二甲基甲酰胺（ＤＭＦ）、Ｎ－甲基吡咯烷酮（ＮＭＰ）、环己酮（ＣＨＮ）、二甲苯、二氯乙烷（ＤＣＥ）和四氯乙烯（ＴＣＥ）中的溶解度，并作出溶解度曲线，为粗蒽的分离和精制提供了有用数据。实验发现ＤＭＦ对粗蒽制取精蒽效果较好，四氯乙烯对粗咔唑的精制效果明显优于传统工艺。

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.
