Numerical analyses were conducted for competitive-consecutive reactions in laminar flow to clarify the mechanism responsible for improvements to product yield with microreactors. The conservation equations of species were non-dimensionalized to derive the dimensionless numbers that governed the flow and reaction in microchannels. Three dimensionless numbers were derived: Peclet number <I>Pe</I>, i.e., the ratio of the diffusion time to the convection time, mixing-reaction number <I>φ</I>, i.e., the ratio of the diffusion time to the reaction time, and <I>K</I>, i.e., the ratio of the secondary reaction rate constant to the primary reaction rate constant. As a result of the numerical analyses of the competitive-consecutive reactions for multilayer laminar flow in microchannels, under conditions where convection was more dominant than diffusion <I>Pe</I> > 10, the product yield of the primary reaction depended on <I>φ</I> and <I>K</I>. A diagram to evaluate product yield was prepared using <I>φ</I> and <I>K</I>. The product yield increased with decreasing <I>φ</I> and <I>K</I>.
