Abstract:
1. A reaction method comprising flowing fluids through a microreactor, coaxially laminating the fluids and causing the fluids to flow as laminar flows whose sections orthogonal to the co-axis are annular, and reacting the fluids by diffusing the fluids in a normal direction of contact interfaces of the fluids, wherein the microreactor has a plurality of fluid supply routes in communication with one reaction channel as a multicylindrical structure having a co-axis and causes a plurality of fluids to flow together in the reaction channel via the respective fluid supply routes, wherein among said plurality of laminated fluids, at least one fluid is a fluid not participating in the reaction of other fluids and wherein the cross-sectional thickness of said fluids participating in the reaction is varied by increasing or decreasing the flow rate of said fluid not participating in the reaction.
