Preparation method of p-Methyl benzoyl chloride
2015
The invention belongs to technical field of organic synthesis and particularly relates to a preparation method of p-Methyl benzoyl chloride. The preparation method comprises the following steps that p-Toluylic acid and sulfoxide chloride react in an organic solvent under the effect of a catalyst, and normal-pressure and reduced-pressure distillation is performed to obtain the p-Methyl benzoyl chloride after reaction is completed. The preparation method is simple in process, high in reaction speed and low in energy consumption, exhaust gas is easy to treat, the used solvent and sulfoxide chloride can be recycled, the product obtained through distillation is high in purity, the yield is also high, and industrial production is easy to achieve.
