To continuously produce the objective synthetic substance simply by continuously flowing solvents containing a raw material dissolved therein.
An apparatus (1) for continuous synthesis is designed to use 2 kinds of solvents having different specific gravities and assuming compatibility/phase separation properties according to the temperature, react a first raw material (X) soluble in the lightweight solvent having a low specific gravity and a second raw material (Y) soluble in the heavy solvent having a large specific gravity in a compatible region and continuously produce the synthetic substance (Z) soluble only in either one of the lightweight solvent and the heavy solvent. The apparatus is equipped with a reaction tube (2) provided with a temperature controller for maintaining the upper stage and the lower stage at a phase separation temperature of each solvent and maintaining the middle stage at the compatible temperature of the solvents, a lightweight solvent feed system (5L) for feeding the first raw material (X) together with the lightweight solvent from the lower end thereof and a heavy solvent feed system (5H) for feeding the second raw material (Y) together with the heavy solvent from the top thereof. Furthermore, a synthetic substance recovering port (12L) for recovering the solvent in which the synthetic substance (Z) is dissolved therein is formed.
