摘　　要：煤焦油中存在一定酚类物质,如果不经处理直接排放,造成的环境污染等将非常严重,因此,在当前的煤化工领域,煤焦油中的粗酚提取已经成为关注的重点问题。基于此,重点探析了煤焦油中粗酚的提取工艺,有效实现了粗酚的回收与利用。There are certain phenolic substances in coal tar,if not directly discharged after treatment,the environmental pollution caused will be very serious,therefore,in the current field of coal chemical industry,the extraction of crude phenol in coal tar has become a focus of attention.Based on this,the extraction technology of crude phenol in coal tar was studied in this paper,and the recovery and utilization of crude phenol were realized effectively.
