Microreactor, method for producing chemical product and manufacturing method of microreactor

摘要

PROBLEM TO BE SOLVED: To realize satisfactory mixing in the mixing of raw material in which a flow rate ratios (volume ratios) are different (different in flow rates).SOLUTION: Provided is a microreactor comprising: a high flow rate side flow passage 102 through which the raw material on the high flow rate side is circulated and a low flow rate side flow passage 103 through which the raw material on the low flow rate side circulates, of raw materials having different flow rates; branched flow passages 102a, 102b obtained by branching the high flow rate side flow passage; and a flow passage 104 for residence as a flow passage after the joining of the branched flow passages 102a, 102b and the low flow rate side flow passage 103, and the branched flow passage 102a and the branched flow passage 102b are joined so as to sandwich the low flow rate side flow passage 103.SELECTED DRAWING: Figure 1
