● 2,4-dichloro-3,5-dimethylphenol is a phenol derivative with certain acidity, and is mainly used as an intermediate in organic synthesis and medicinal chemistry.
● In a three-necked flask equipped with a reflux condenser (open to air), add phenol and manganese sulfate catalyst to water, introduce gaseous hydrochloric acid and dissolve into an aqueous solution, immerse the flask in a preheated oil bath, and stir vigorously with a magnetic stirrer Stir, and slowly add H2O2 (30% concentration solution) dropwise with a syringe during the reaction, and let the mixture stand for 1.5 hours, so that the water and the organic layer in the reaction system can be separated into two phases. The organic phase was collected, dried with anhydrous sodium sulfate, and the obtained filtrate was filtered and concentrated under vacuum, and the target product 2,4-dichloro-3,5-di methyl phenol.
