We can compare performance of the reactor developed in this work and the obtained materials with the reported to-date precipitation syntheses of LDHs in flow in the open literature. There is a very small number of reports of continuous synthesis of LDHs in the open literature. Thus, a study of the effect of different mixing regimes attained in a microchannel reactor compared with a stirred tank baffled reactor on particle size distribution of hydrotalcites demonstrated that hydrotalcites particles of smaller mean size are obtained in flow with a lower power input, compared to the stirred tank . The particle sizes obtained were in the order of 10 µm, which are claimed to be non-agglomerated. This, however, was not supported by any structural characterization of the synthesized materials; particles of hydrotalcites in this range of sizes are certainly agglomerates. As we have shown above, the primary crystallites of hydrotalcites are in the order of 9-12 nm and any observed larger structures are aggregates.
