The invention discloses a method for preparing o-chlorobenzaldehyde by continuously oxidizing o-chlorotoluene and belongs to the technical field of an organic synthesis technology. The method is a process technology which takes an o-chlorotoluene compound as a raw material, one or more metal ion complexes of cobalt, molybdenum and bromine as a catalyst, hydrogen peroxide as an oxidant and acetic acid as a solvent, and is used for preparing o-chlorobenzaldehyde by continuously oxidizing o-chlorotoluene in a tubular reactor. The method disclosed by the invention has the advantages of moderate conditions, short reaction time and high raw material utilization rate; effective control in a reaction process can be realized; the method is safe and stable, is continuously operated and has high production efficiency.
