| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| Biological activity | 2,6-Dimethoxybenzoic acid is a polyphenol compound found in plant-derived foods. |
| use | 2,6-dimethoxybenzoic acid is an intermediate of acaricide benzoite. Used as a pharmaceutical intermediate Organic synthesis. Pharmaceutical intermediates. |
| Production method | 2, 6-dimethoxybenzoic acid can be synthesized by a three-step reaction. The first step: using N,N-dimethylformamide (DMF) as solvent, resorcinol: potassium carbonate: carbon dioxide = 1.0: 0.5: 1.5, reaction at 1.3MPa,135~137 ℃ for 16.5h, and acidification to prepare 2,6-dihydroxybenzoic acid. Step 2: Make 2, 6-dihydroxybenzoic acid: dimethyl sulfate = 1:3, and react under alkaline conditions to obtain 2, 6-dihydroxybenzoate. Step 3: The product of the previous step is hydrolyzed and acidified by alkali catalysis to prepare 2, 6-dimethoxybenzoic acid. |
