摘　　要：综述了2,6-萘二甲酸合成技术的国内外研究进展,主要介绍了2,6-二烷基萘氧化法、β-甲基萘酰化氧化法的特点,指出2,6-二甲基萘氧化法是较具竞争力的生产方法,建议充分利用我国的萘和烷基萘资源来制备2,6-二甲基萘,以降低生产成本。The progress in the synthesis technology of 2, 6-naphthalene dicarboxylic acid （2, 6-NDA） at home and abroad are reviewed. The characteristics of 2,6-dimethy naphthalene oxidation method and ]J-methyl naphthalene ac- ylation oxidation method are mainly introduced. Among these methods, oxidation of 2, 6-dimethylnaphthalene to pro- duee 2, 6-NDA is more competitive than others. It is suggested that making full naphalene resources in our country to prepare 2,6-dimethyl nathalene to reduce use of naphthalene and alkyl production cost.
