What is the preparation method of 2,5-dichlorobenzene-1,4-dicarboxylic acid?
2% 2C5-difluorobenzene-1% 2C4-dicarboxylic acid, the preparation method is as follows:
Take an appropriate amount of p-xylene, place it in a reactor, and use an appropriate amount of fluorine-containing reagents, such as hydrogen fluoride, under specific temperature and pressure conditions, the p-xylene is fluorinated, and fluorine atoms are introduced at the 2nd and 5th positions of the benzene ring to obtain 2% 2C5-difluoro p-xylene. This reaction requires strict temperature control. If the temperature is too high, side reactions will easily occur, and if it is too low, the reaction rate will be slow.
Then, the obtained 2% 2C5-difluoro-p-xylene is heated and refluxed in a suitable solvent environment, such as an alkaline aqueous solution, with a strong oxidant, such as potassium permanganate. This step aims to oxidize two methyl groups of p-xylene to carboxyl groups to obtain 2% 2C5-difluorobenzene-1% 2C4-dicarboxylic acid. During the reaction process, it is necessary to pay attention to observe the color change and temperature change of the reaction to ensure that the reaction is fully carried out. After the reaction is completed, through cooling, filtration, washing, drying and other post-processing steps, a pure 2% 2C5-difluorobenzene-1% 2C4-dicarboxylic acid product can be obtained.
Another method is to use 2% 2C5-difluorobenzaldehyde as the starting material, first oxidize it with a suitable oxidant, such as Jones reagent, to 2% 2C5-difluorobenzoic acid, and then through a specific carboxylation reaction, the carboxyl group is introduced into the 4 position of the benzene ring to obtain the target product. In this way, the precise control of the reaction conditions at each step is crucial. Factors such as the pH, temperature, and time of the reaction have a significant impact on the yield and purity of the product. During the operation, relevant safety procedures must also be followed, and various chemical reagents must be properly handled to ensure the safety and efficiency of the preparation process.
