摘要
芴是重要的有机化工原料,多从煤焦油的洗油馏份中提出,也可从蒽油中提出。芴的提取精制过程是先间歇蒸馏洗油馏份或蒽油馏份切取芴主馏份,再采用冷却结晶法或溶剂结晶法精制芴主馏份得到芴。
Fluorene is an important material in organic chemical industry. It is usually extracted from the washing oil or anthracene oil distillate of coal tar. The extraction and refining process includes distillating washing oil or anthracene oil to get fluorene distillate, then crystallizing the fluorene distillate to get fltiorene using cooling or solvent.
