摘　　要：2,6-萘二甲酸二甲酯(DM-2,6-NDC)是一种重要的中间体,是合成功能聚合物聚萘二甲酸乙二醇酯(PEN)的重要原料,对于其合成技术的研究一直是国内外的研究热点。本文综述了2,6-萘二甲酸(2,6-NDC)的合成方法及2,6-萘二甲酸酯化制备2,6-萘二甲酸二甲酯的研究现状及存在的问题,并对2,6-萘二甲酸二甲酯的发展前景进行了展望。笔者认为,以煤化工副产物煤焦油为原料合成2,6-萘二甲酸二甲酯以及新材料PEN,是国内煤化工企业的一条重要出路。Dimethyl 2,6-naphthalenediformate(DM-2,6-NDC)was an important intermediate and raw material for the synthesis of functional polymer polyethylene naphthalate (PEN). The research had been the focus in China and abroad. In this paper, the research status and existing problems of the synthesis of 2, 6-naphthalene dicarboxylic acid( 2,6-NDA)and the esterification of 2,6-NDA to prepare DM-2,6-NDC were summarized, meanwhile the future development of DM-2,6-NDC was forecasted. The author believed that coal tar products was used as raw materials to synthesize DM-2,6-NDC and new materials PEN, was an important way for domestic coal chemical enterprises.
