摘 要: 以氯苯为溶剂 ,在不同温度下用 50 %的氢氧化钾溶液、活性白土、90 %的硫酸溶液处理工业菲 ,然后冷却、结晶获得了纯度 98 4 %~ 99 2 %的精菲 ,收率 83%以上 .母液可以循环使用 ,溶剂可以回收 . Crude phenanthrine was treated with 50% potassium hydroxide,activated bentenite and 90% sulfuric acid.After recrystallization with chlorobenzene,the refined product was obtained,whose purity was 98.4%~99.2% and yield was 83%.The solvent can be used repeatedly.
