摘　　要：综述了从石油和煤焦油中分离、提纯2,6-二甲基萘(2,6-DMN)的工艺,即溶剂结晶法、共熔结晶法、吸附法、压力结晶法、乳化结晶法等。分别论述了不同工艺的优缺点,对2,6-DMN分离、提纯技术的发展提出建议,并指出共熔结晶法和溶剂结晶法相结合的工艺较易实现工业化,是以后的发展方向。In this paper, several kinds of separation way of producing 2,6-dimethylnaphthalene, such as solvent crystallization, eutectic crystallization, adsorptive separation, pressure crystallization and emulsion crystallization were reviewed. The trends of development and superiority of these methods are also elaborated. The paper also point out, the combination of solvent crystallization and eutectic crystallization are easy to industrialization, is the progress direction in the future.
