摘要
研究了从粗蒽中提取菲的方法 ,即用乙二醇对原料进行共沸 ,以四氯化碳为溶剂并用硫酸处理 ,最后用无水乙醇重结晶 ,制定出最佳的工艺路线 .
A new method on extraction of phenanthrene from crude anthracene is given,which includes azeotropic dissolution with ethylene glycol,extraction of carbon tetrachloride,treatment of sulfuric acid and ethyl alcohol recrystallization,in the end,the best process is obtained.
