摘　　要：本文重点描述分析、比较了水相法、溶剂法合成2,6-二羟基苯甲酸的反应机理、反应条件及后处理方法,并由此得出结论:在溶剂中溶剂法合成2,6-二羟基苯甲酸从各个方面优于以水做溶剂合成水相法。而且在生产上切实可行,产品纯度可达99%以上。The reaction mechanism, conditions and post-treatment method of synthesis of 2,6-dihydroxybenaoic acid were reviewed in this paper. The conclusion was obtained that synthesis of 2,6-dihydroxybenzoic acid in solvent was better than in water, suggesting that it should be a feasible method for synthesis of 2,6-dihydroxybenaoic acid with the purity of over 99%.
