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，对芴与2-甲基氧芴两元物系的固液平了推测分析。

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.

芴纯度的提高主要不是依赖苊、氧芴的去除,而是其它杂质的分离。
