PROBLEM TO BE SOLVED: To provide a reaction method capable of preventing the production and accumulation of a polymerization product by carrying out the reaction in a reaction system containing a polymerizable substance, while the upper inner wall of a reaction vessel above the surface of a liquid is always covered and wet with the reaction liquid and the mists and splashes of the reaction liquid. SOLUTION: This reaction method comprises reacting in a reaction system containing a polymerizable substance as a raw material or its product, while the upper inner wall of the reaction vessel above the surface of a liquid is always covered and wet with the reaction liquid and the mists and splashes of the reaction liquid. When the reaction is e.g. a Diels Alder reaction, the reaction is carried out by reacting a dienophile such as maleic anhydride with a diene such as butadiene. The reaction method includes a method for stirring the reaction liquid with a stirring blade. The effect for preventing the production and accumulation of a polymerization product can be enhanced, for example, by attaching a device for upward jetting out a reaction liquid to a place above the surface of the liquid, jetting the reaction liquid, and further attaching a diffusion device 1 and a diffusion plate for enhancing the diffusion of the reaction liquid.
