For the reactor developed in this work, given its ID and the flow rates used, the space time, also equal to mean residence time, is estimated to be 0.34 s. The reactor' Re number is approximately 2,857. For the composition of the reaction mixture and the conditions used in this study the theoretical limit of the micromixing time is 0.4 s. This is calculated using the engulfment mixing model and the estimated energy dissipation rate (0.0032 W kg -1 ) . Thus, we operate the reactor at residence time close to the micromixing time. This is significantly faster than a cylindrical flask with a magnetic stir bar (~9.3 s) and is responsible for attaining smaller particles with narrow particle size distributions. Further dilution of the product mixture in the large volume of the aging vessel should reduce growth of primary particles and limit their aggregation.
