摘要
用精馏、结晶法可以从苊油中提取纯度≥97%的精芴,讨论了精馏、结晶和洗涤的工艺条件对芴的纯度和收率的影响,原料中的芴含量越高,回收率越高。
Refined fluorine with purity of 97% can be extracted from acenaphthylene oil by rectification and crystallization process. The influence of the process conditions of rectification, crystallization and scrubbing on fluorine purity and recovery yield is discussed, the higher the fluorine content in feedstock, the higher the recovery yield.
