摘　　要：实验研究了乳化结晶法制备精蒽的新工艺,考察了乳化剂用量、水/溶剂质量比以及助剂加入量等因素对精蒽质量的影响。实验结果表明,以苯乙酮作溶剂,采用十二烷基苯磺酸钠(SDBS)和Span20复合型乳化剂,经一次乳化结晶所得精蒽纯度大于95%,符合国家一级精蒽标准。A new technology of refined anthracene preparation by emulsion crystallization method is studied in laboratory where the factors affecting the quality of refined anthracene,such as amount of emulsifier,ratio of water to solvent（ w /w） and amounts of additives,etc. have been investigated. The result shows that the purity of pure anthracene can reach above 95% and meet national specification Gr. I after primary emulsification when a compound emulsifier（ SDBS ＋ Span20） is adopted and acetophenone is used as solvent.
