acenaphthene

In the presence of acetic acid and polyethylene glycol, chromic anhydride and acenaphthene react under mild condition and acenaphthene can completely convert into acenaphthenone.

在醋酸、聚乙二醇存在下 ,铬酸酐苊在温件下反应 ,苊可完全转化为苊酮。

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.

芴纯度提高要不是依赖苊、氧芴去除,而是其它杂质分离。
