Abstract:
1. A microreactor for mixing and discharging two raw material liquids, the microreactor obtained by laminating a base plate, a raw material introducing plate and a mixing fluid channel plate, the base plate having a first raw material introducing fluid channel formed therein for introducing one of the two raw material liquids, the raw material introducing plate having a second raw material introducing fluid channel formed therein for introducing the other of the two raw material liquids, the mixing fluid channel plate being arranged between the base plate and the raw material introducing plate, and the mixing fluid channel plate having a mixing fluid channel formed therein for mixing the two raw material liquids, the microreactor comprising: a mixing fluid channel formed in the mixing fluid channel plate, such that in a downstream direction towards an outlet orifice, a cross-section of a portion of the mixing fluid channel becomes narrower in a width direction; and a mixing fluid channel formed in the base plate, such that in a downstream direction towards the outlet orifice, a cross-section of a portion of the mixing fluid channel becomes deeper in a depth direction; wherein the mixing fluid channel in the base plate communicates with the mixing fluid channel in the mixing fluid channel plate, and is connected to the outlet orifice to discharge the mixed raw material liquids; wherein each of the base plate and the raw material introducing plate include a plurality of alignment holes for setting a displacement amount forward or backward; and wherein a size of an opening through which one of the two raw material liquids flows from the first raw material introducing fluid channel into the mixing fluid channel in the mixing fluid channel plate, and a size of an opening through which the other of the two raw material liquids flows from the second raw material introducing fluid channel into the mixing fluid channel in the mixing fluid channel plate, are adjusted by selecting an alignment hole.
