摘　　要：The refining process of fluorene by melt crystallization was experimentally studied.The effects of the cooling rate,final temperature in the crystallization process,heating rate and final temperature in the sweating process on the purity and yield of the product were investigated.The optimum conditions of the refining process of fluorene by melt crystallization were determined and a product with purity of 97.4% was obtained.The binary solid-liquid equilibrium phase diagram for fluorene and 2-methyl-diphenylene oxide is analyzed according to the experimental results.The refining process of fluorene by melt crystallization was experimentally studied.
