Preparation method of O-nitrobenzaldehyde

The invention relates to a preparation method of o-nitrobenzaldehyde, which comprises the following steps: preparing 1,2-bis(o-nitrophenyl)ethylene by using required products nitrobenzaldehyde and nitrotoluene as raw materials, and carrying out high-efficiency oxidation by using ozone with proper concentration to obtain the final product nitrobenzaldehyde. The preparation method has the beneficialeffects that only a proper amount of alkali is used for catalysis in the condensation reaction, and the intermediate product 1,2-bis(o-nitrophenyl)ethylene can be efficiently obtained by using a conventional solvent to carry out a reaction with water; a gas-liquid reaction then is carried out by using a micro-channel reactor to finally obtain the required nitrobenzaldehyde. The method has the advantages of low use amount of raw materials, high reaction yield, few byproducts and impurities, simple and feasible purification operation and convenience for industrial production in workshops.
