To predict the conditions for improving chemical reaction yield in a microreactor, the relationship between chemical reaction and molecular mixing was analyzed by Monte Carlo simulation. The targeted chemical reaction in the microreactor is the consecutive reaction, where k1 is the reaction-rate constant of the first stage, and k2 is the reaction-rate constant of the second stage. The non-dimensional Damkohler number Da is defined as the ratio of a chemical reaction time to a molecular mixing time. It was found that the reaction yield of main product was improved by using a microreactor when the ratio of the reaction rate constants is k1/k2>1. To validate the Monte Carlo simulation results described above, the validation experiments of four kinds of consecutive reactions were conducted using both the microreactor and the conventional batch method. It was found that the experimental results were good agreement with the predicted results by Monte Carlo simulation.
