The deep processing and utilization of wash oil in my country is still backward in industrial technology, with serious pollution during processing and low yield. In order to increase the yield of fluorene, make full use of domestic fluorene resources to meet the growing demand for fluorene. Based on experiments and actual industrial production operations, it was discovered that to improve the quality and yield of industrial fluorene products, it must start with the raw materials, and carry out strict process control on the selection of solvents, the ratio of solvents and materials, and crystallization operations. Can effectively increase product output and product yield. The increase in the output and quality of industrial fluorene has certain economic and social benefits.
