2,6-二甲基萘制备技术研究进展

摘要

This paper reviews extraction and synthesis processes of 2,6-Dimethylnaphthalene(2,6-DMN),which include direct extraction from petroleum coke,coal tar,and chemical synthesis process with naphthalene and methyl naphthalene,toluene and xylene as raw material.The o-xylene / butadiene alkylation route is proved to be suitable for mass production thanks to available feedstock with broad prospects for development.%文章综述了2,6-二甲基萘的提取和合成技术,包括从石油焦油、煤焦油直接提取技术和以萘、甲基萘、甲苯和二甲苯为原料的化学合成工艺,同时阐明邻二甲苯/丁二烯烷基化路线因为原料易得,适合大规模生产,开发前景广阔.
