description The invention belongs to the technical field of photocatalytic organic chemical synthesis, and relates to a method for continuously preparing isobutylphenylpropionic acid by using a microchannel module reaction device. The preparation method comprises the following steps: dissolving isobutylbenzene and methyl 2-bromopropionate in a solvent to obtain a solution A; dissolving a photocatalyst and alkali in a solvent to obtain a solution B; respectively and simultaneously pumping the solution A and the solution B into a first micro-structure reactor of a micro-channel module reaction device for photoreaction to obtain a first reaction solution; respectively and simultaneously pumping the obtained first reaction solution and an acidic aqueous solution into a second microstructure reactor of the microchannel module reaction device for hydrolysis reaction to obtain a second reaction solution; washing, extracting, separating and purifying the second reaction liquid to obtain the isobutylphenylpropionic acid.
