摘　　要：采用甲苯为溶剂溶解粗蒽,利用溶剂萃取、共沸和重结晶的方法制取精蒽,利用蒸馏和重结晶的方法制取精菲,利用混合溶剂和重结晶的方法制取精咔唑.考察了溶剂用量、水浴温度和共沸温度对产品纯度的影响,确定了最佳的溶剂用量、最佳的水浴温度和共沸温度.分离得到的蒽的纯度达到了97.882%,咔唑的纯度达到了91.722%,菲的纯度达到了75.704%.利用红外光谱表征了产物与标准品的结构,并进行了比较分析,利用气相色谱分析了产物中蒽、咔唑和菲的含量.The toluene was used as solvent to dissolve crude anthracene. The methods of sovlent extraction, azeotropic and recrystallization were used to prepare refined anthracene. The methods of dis- tillation and recrystallization were used to prepare refined phenanthrene. The methods of mixed solvent and recrystallization were used to prepare refined carbazole. The effect of solvent quality, water-bath temperature and azeotropic temperature on the product purity were ivestigated and the best solvent quality, water-bath temperature and azeotropic temperature were determined, in this condition the purity of anthracene, carbazole and phenanthrene from separation could reached 97. 882%,91. 722% and 75. 704%. The structure of production and standard were characterized by infrared spectra and the result was compared and analyzed. The content of anthracene, carbazole and phenanthrene in the product were analyzed by gas chromatography.
