Technical development of separation and refinement anthracene phenanthrene and carbazole from crude anthracene

综述了从粗蒽中分离和精制蒽、菲、咔唑的技术进展,介绍了物理分离法、化学分离法和复合法,并对各种方法进行了评述。结果表明,复合法因其流程简单、投资低和无环境污染等,具有推广价值。

The technical development of separation and refinement anthracene, phenanthrene and carbazole from crud anthracene was summarized in this paper. The physical methods, the chemical methods and the combined process were introduced and the advantages and disadvantages of these methods are reviewed. The combined process is characterized by simple production process, low investment, no environmental pollution and so on, and it is worth to popularize the process.
