FLOW TYPE FINE REACTION PASSAGE, REACTION APPARATUS AND REACTION METHOD

摘要

PROBLEM TO BE SOLVED: To improve the productivity of a desired material by efficiently mixing reaction fluids and securing the reaction time in a confluent part while suppressing the increase of pressure loss in a flow type fine reaction passage, a reaction apparatus and a reaction method. SOLUTION: In the fine flow type reaction passage 3 provided with a plurality of introducing flow passages 10A and 10B each having a fine cross-sectional surface area and a confluent passage 20 formed by joining the introducing flow passages 10A and 10B in the confluent part 15 and for joining and reacting the reaction fluids FA and FB flowing through each introducing flow passage 10A and 10b with each other in the confluent passage 20, the confluent passage 20 is structured to be provided with a throttle part 21 having a smaller cross-sectional surface area than the sum total of that of each introducing flow passages 10A and 10B formed in the confluent part 15 and an expanded part 22 provided in the downstream side of the throttle part 21 and having a larger cross-sectional surface area than that of the throttle part 21.
