【Task】 The subject of this invention is providing the simple manufacturing method which can obtain aromatic monomers, such as vanillin and vanillic acid which can be utilized as raw materials, such as a phenol resin and an epoxy resin, using wood as a raw material with a high yield. [Solution] In the step of digesting wood with soda, oxygen is added, quinone compound is added in an amount of 0.001 to 10% by mass per absolute dry weight of wood, and the method includes a step of digesting soda with a liquid ratio of 5.0 or more. Group monomers are produced. [Selection figure] None |
