1.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.
芴纯度主要不是依赖苊、氧芴去除,而是其它杂质分离。
2.The binary solid-liquid equilibrium phase diagram for fluorene and 2-methyl-diphenylene oxide is analyzed according to the experimental results.
