Abstract
AbstractIn the context of achieving continuous synthesis of acyl peroxides using microreactors, continuous preparation of alkaline hydrogen peroxide (AHP) solution is required. However, two key issues, Na2O2 precipitation and H2O2 decomposition, need to be considered or addressed. For the precipitation of Na2O2 during NaOH and H2O2 mixing, experiments revealed that precipitation could be avoided by appropriate selection of operation window. For the risk of violent H2O2 decomposition when NaOH and H2O2 solutions are one‐step mixed, theoretical approaches were adopted. Simulation‐derived mixing time is combined with decomposition kinetics to find a direct relationship between operation‐structure parameters and percentage of decomposed H2O2. This percentage is estimated to be in the order of 10−4 for micromixing devices, which indicates that micromixing devices can be used to one‐step mix NaOH and H2O2 solution without causing violent H2O2 decomposition. This work provides insights into the preparation of AHP solution and facilitates its continuous preparation.
