摘　　要：本文综述了2,6-萘二甲酸(NDA)的合成方法。烷基萘氧化法制得的NDA粗品收率80%～90%,Henkel羧基转移法收率60%～80%,2-甲基-6-乙酰基萘氧化法两步总收率62%。认为采用煤焦油产品为原料合成2,6-萘二甲酸以及新材料PEN是国内煤化工企业的一条重要出路。Synthesis methods of 2,6-naphthalenedicarboxylic acid （NDA） were reviewed. The yield of crude NDA prepared by alkyl naphthalene oxidation was 80% - 90%, the yield of Henkel earboxyl transfer was 60%- 80% Total yield of 2-methyl-6-acetylnaphthalene oxidation was 62%. It was considered that synthesizing NDA and PEN from coal tar was an important outlet for coal chemical industry.
