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

同实验结果，对与2-甲基氧两元物系固液平衡相进行了推测分析。

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、氧除,而是其它杂质分离。
