| Abstract：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%. |
| Key words：2; 6-dihydroxybenzoic acid; the synthesis method in solvent; synthesis |
