摘要
利用一种简易的液固相平衡测定装置，测定了蒽在二甲基甲酸胺（ＤＭＦ）、Ｎ－甲基吡咯烷酮（ＮＭＰ）、环己酮（ＣＨＮ）、二甲苯和二氯乙烷中的溶解度，并作出溶解度曲线，为粗葱加工提供了数据．实验发现ＤＭＦ中加入另一种含胺基化合物后降低蒽的溶解度，对粗蒽精制效果更好．
Using a phase equilibrium apparatus, the solubilities of anthracene in dimethyformamide (DMF ), N--methylpyrrolidinone (NMP ), cyclohexanone (CHN ), xylene and dicloroethane were determined and solubility curves were drawn,providing useful data for crude anthracene processing. It was found that addition of an amine compound in DMF can reduce the anthracene solubility in DMF and favour the refining of crude anthracene.
