The invention discloses a method for preparing azithromycin by using a microchannel reactor. The method uses erythromycin as a starting material and prepares azithromycin through oximation, rearrangement, reduction and methylation reactions. During the oximation reaction, the contact time of the feed liquid in the microchannel reactor is very short, which greatly reduces the safety risk of the oximation reaction. The reduction reaction is carried out in the microchannel reactor, and neither explosive sodium (potassium) borohydride nor a high-pressure reactor is used, which reduces the safety risk. A tray layer of palladium carbon is laid on the reaction bed to achieve the hydrogenation target, while greatly improving the utilization efficiency of palladium carbon. In the rearrangement reaction, a milder leaving group, sodium 2-naphthalenesulfonate, is used to replace the existing leaving group. Water is used as a solvent and the reaction is carried out at room temperature. The method is green, safe, and has a high yield, and is suitable for industrial production.
