Summary:The invention belongs to the technical field of preparation of p-methylsulfonyl benzaldehyde, and particularly relates to a preparation method of p-methylsulfonyl benzaldehyde, which comprises the following steps: 1, preparing an intermediate product p-methylthio benzaldehyde, and 2, preparing a final product p-methylsulfonyl benzaldehyde by using the intermediate product p-methylthio benzaldehyde and hydrogen peroxide. In the second step, purified water is added into an oxidation reaction kettle, then concentrated sulfuric acid and an oxidation catalyst are sequentially added, and finally intermediate products p-methylthio benzaldehyde and hydrogen peroxide are dropwise added into the oxidation reaction kettle containing dilute sulfuric acid at the same time; compared with the prior art, the method has the beneficial effects that hydrogen peroxide is independently dropwise added into the oxidation reaction kettle, and compared with the traditional process that hydrogen peroxide is added into the oxidation re
