Two-solution microreactor having sector-shaped grooves

摘要

A two-solution micro-chemical reactor using a micro reactor which can develop reaction with high efficiency and can increase a solution flow rate available for the reaction. A sector-shaped groove is formed in a flow-passage groove substrate used in the micro reactor to extend from a central portion to an outer peripheral portion of the substrate such that the sector-shaped groove has a substantially constant depth and has a flow passage width gradually decreasing to become smaller in proportion to a distance from a central portion of the flow-passage groove substrate. First branched inlet holes for introducing a first solution and second branched inlet holes for introducing a second solution are alternately arranged in an outer peripheral portion of the sector-shaped groove.
