The invention relates to a catalytic synthesis method of 3-methoxyl-4-hydroxybenzyl alcohol. The method takes guaiacol and formaldehyde as raw materials, adopts inorganic base or one or the mixture of a plurality of inorganic bases as a catalyst and takes aqueous solution or the mixture of water and organic solvent as a solvent, the reaction lasts for 30 minutes to 300 minutes, the reaction temperature is 5 DEG C to 60 DEG C and such side reactions as product polymerization, dismutation and the like caused by high temperature are avoided. The method not only has cheap raw materials which are easy to obtain, but also has simple technique, low energy consumption and fairly high industrial practicability and is environmentally friendly. |
