DCMX

2,4-dichloro-3,5-dimethylphenol(DCMX) Cas No.:133-53-9 is a phenol derivative with a certain acidity, mainly used as an intermediate in organic synthesis and medicinal chemistry In a three necked flask equipped with a reflux condenser (open to air), phenol and manganese sulfate catalyst are added to water. The production of 2,4-dichloro-3,5-dimethylphenol(DCMX) Cas No.:133-53-9 are as belows: Gaseous hydrochloric acid is introduced and dissolved into an aqueous solution. The flask is immersed in a preheated oil bath and vigorously stirred with a magnetic stirrer. During the reaction, H2O2 (30% concentration solution) is slowly added dropwise using an injector. The mixture is left to stand for 1.5 hours to separate the water and organic layers in the reaction system. Collect the organic phase, dry it with anhydrous sodium sulfate, filter and concentrate the filtrate under vacuum. The target product 2,4-dichloro-3,5-dimethylphenol is obtained by silica gel column chromatography (using pure petroleum ether as eluent).
