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，与2-甲基氧两元物系的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.

纯度的提高主要赖苊、氧的去除,而其它杂质的分离。
