What is the preparation method of 2,5-dimethylbenzenesulfonic acid?

To prepare 2,5-dimethylbenzoic acid, you can follow the following method.
Take 2,5-dimethylbromobenzene first and use it as the starting material. In a clean reactor, add an appropriate amount of anhydrous ether as a solvent, and pass in high-purity nitrogen to remove the air in the kettle to create an oxygen-free environment. Then, slowly put the magnesium chips into the kettle, turn on the stirring device, so that the magnesium chips are evenly dispersed in the solvent. Under low temperature and dark conditions, slowly add the ether solution of 2,5-dimethylbromobenzene dropwise. This process requires close attention to the change of reaction temperature to ensure the smooth progress of the reaction. After the dropwise addition is completed, maintain the low temperature and stir for a period of time to allow the Grignard reagent to be fully formed.
The generated 2,5-dimethylphenylmagnesium bromide Grignard reagent is an extremely critical intermediate. Take another reaction vessel, inject an appropriate amount of dry ice (solid carbon dioxide), and slowly pour the prepared Grignard reagent into it. As the reaction progresses, the carbon dioxide reacts with the Grignard reagent gradually to generate the corresponding carboxylate. After the reaction, carefully add an appropriate amount of dilute sulfuric acid to the system to neutralize the reaction system and convert the carboxylate into 2,5-dimethylbenzoic acid. At this time, the solution will be stratified.
Separate the organic phase with a separation funnel, and then extract the aqueous phase with an organic solvent such as ether to combine the organic phases. The organic phase is washed successively with saturated sodium bicarbonate solution and distilled water to remove impurities. Subsequently, an appropriate amount of anhydrous sodium sulfate is added to dry the organic phase to remove the moisture.
Finally, the dried organic phase is transferred to a distillation device, first distilled under atmospheric pressure to remove most of the solvent, and then distilled under reduced pressure to collect the fraction within a specific temperature range, and pure 2,5-dimethylbenzoic acid can be obtained. After further purification by means of recrystallization, high-quality target products can be obtained. Although this preparation method is complicated, 2,5-dimethylbenzoic acid can be effectively prepared, and the product purity is high.
