Who / What
A microreactor is a tiny device that facilitates chemical reactions within a confined space typically below 1 mm in lateral dimension. Most commonly, these devices comprise microchannels that enable continuous flow reactions, distinguishing them from traditional batch reactors.
Background & History
Microreactors emerged within the field of micro process engineering, alongside related devices such as micro heat exchangers that handle physical processes on a microscopic scale. Their development reflects a broader interest in scaling chemical reactions through confinement rather than increasing reactor size. Over time, the concept of microchannel confinement has become a standard in designing continuous flow reactors that offer precise control over reaction parameters.
Why Notable
By operating in micro‑confined spaces, microreactors provide superior heat and mass transfer, leading to higher reaction efficiencies and safety. They enable the scaling up of processes through numbering‑up strategies rather than scaling up, which is critical for industrial chemistry and research. Their continuous flow nature also facilitates integration with analytic techniques for real‑time monitoring and quality control.
