| Abstract: | 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%. |
