摘　　要：文章以粗蒽为原料、DMF复配溶剂的最佳结晶条件是保温温度为90℃,保温时间50min,冷却结晶温度为25℃,保温时间50min,固液比1.8g/ml。结果表明:这一方法使溶剂得以循环利用,环境污染小,且成本低,精蒽的纯度可达96%以上,收率达到67%以上。In this paper,we take crude anthracene as raw material,and DMF as the solvent to prepare refined anthracene. The optimum crystallization condition for DMP are determined as below： dissolved temperature 90℃,crystal- keeping time 50 min,solvent ratio 1. 8g /ml,cooling crystallization temperature 25℃,cooling crystallization time 50 min. The results show that the process hardly has environmental pollution,the solvent is circularly utilized,the cost is lower,the purity of refined anthracene can reach to more than96%,the total recovery yield of refined anthracene is higher than 67%.
