The improvement of the purity of fluorene is not dependent on the removal of acenaphthene and dibenzofuran, but dependent on the separation of other impurities.

纯度提高主要不是依赖苊、去除,而是其它杂质离。

The binary solid-liquid equilibrium phase diagram for fluorene and 2-methyl-diphenylene oxide is analyzed according to the experimental results.

同时根据实验结果，2-甲基两元物系固液平衡相图进行了推测析。
