Uses | 2, 4-dichloro-5-nitrophenol is an intermediate of the herbicide oxalone. |
production method | its preparation method is to put 2,4-dichlorophenol and lye into a reaction kettle, start stirring, drop protective agent at an appropriate temperature, keep the temperature for several hours after dropping, cool and filter to obtain 2,4-dichlorophenyl alkoxy compound, and then add concentrated nitric acid and water in another reaction kettle, add sulfuric acid dropwise in the reaction kettle to generate mixed acid, add the above-mentioned phenylalkoxy compound and solvent in another reaction kettle, start stirring, cool, add mixed acid dropwise in the reaction liquid, and slowly heat up to a certain temperature after the dropwise addition, react for several hours, delaminate, dedissolve the organic layer, and cool to obtain a phenylalkoxy nitrate solid. Then the nitrate is transferred into the reaction kettle, lye is added for hydrolysis, dilute acid is added to obtain yellow precipitation after hydrolysis, and the product is filtered. |
