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,经冷却、结晶获得纯度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。
Purification of crude phenanthrine is dealed with 50% potassiu hydroxide solution activated bentonite 90% sulfuric acid solution and recrystallization at different temperatures in the chlorobenzene. The purity of product is 99.2% . The average yield is more than 83 %. The recovered solvent and mother solution can be circulative used.
