A first object of the present invention is to provide an oxidation treatment apparatus and an oxidation treatment method for toluene, which are excellent in reaction efficiency and secondly and easily realized. In the oxidation treatment apparatus 2 and the oxidation treatment method, a microreactor 1 is used and has a micro flow path 3, a photocatalyst 4, and an ultraviolet irradiation means 5. The photocatalyst 4 exhibits oxidizing power when irradiated with ultraviolet rays. In the microchannel 3, first, the injected toluenes are oxidized to benzyl cations, and then the benzyl cations move to the water injected in the middle and react with water to form benzyl alcohol, and then benzyl Alcohols are oxidized to benzaldehydes. The oxidation reaction is performed by molecular diffusion at the interface 17 between the laminar flow toluene layer 14 and the photocatalyst 4 and at the interface 18 between the laminar water layer 15 and the photocatalyst 4. Further, the transfer to water and the reaction with water are carried out by molecular diffusion at the interface 16 between the toluene layer 14 and the water layer 15. [Selection] Figure 1 |
