Kind Code: A1 The same microreactor can cope with various reactions and condition changes, and a reaction channel is not clogged and clogged with aggregates and precipitates generated by the reaction. A plurality of supply paths 50, 52 and 54 communicating with one reaction flow path 56 are formed into a concentric multiple tube structure, and a plurality of fluids L1, L2 and L3 are supplied to the respective supply paths 50, 52 and 54. The fluids L1, L2, and L3 are stacked on a concentric axis, and the cross-section perpendicular to the concentric axis is circulated as an annular laminar flow, while allowing the fluids to contact each other at the contact interface. At the time of the reaction of the microreactor in which the reaction is performed by diffusing in the normal direction, at least one of the stacked fluids L1, L2, and L3 is composed of a fluid that does not participate in the reaction with other fluids. To do. [Selection] Figure 1 |
