Abstract

A flow reactor can promote a reaction under appropriate temperature management, can precent reaction fluid or generated gas from being trapped in a heat transmission part, can be disassembled for easy cleaning, and to which a coating or lining can be applied. This flow reactor is provided with two flow paths, a reaction flow path and a second flow path, in a space formed between an inner cylinder and an outer cylinder that are concentric. A spiral heat transmission body is disposed between the inner cylinder and the outer cylinder, and the spiral heat transmission body has a substantially triangular cross-sectional shape in an axial cross-sectional view. The spiral heat transmission body partitions the space into the reaction flow path and the second flow path, and heat is exchanged via the spiral heat transmission body between a reaction fluid F1 flowing through the reaction flow path and a heat medium F2 flowing through the second flow path.
