There are other possibilities to affect mixing and hence nucleation step in the hydrotalcite synthesis, apart from performing the reaction in flow. For example, synthesis was performed in batch under high sheer mixing, affording primary crystallite sizes of ∼ 14-30 nm depending on Al:Mg ratio, and resulting in the disk-like particles with a relatively narrow size distribution of the aggregates with the mean of ∼0.1 µm . In this work the rates of mixing were significantly enhanced due to high sheer in the colloidal mixer, but the operation was batch-wise with 60 s reaction time, followed by aging. Improvement in mixing time is a significant advance over conventional batch syntheses of HTs, but the broad residence time distribution of the batch reactor will favor, by its physical nature, broad distribution of compositions and hence of primary crystals and then the aggregates. High sheer mixer was later implemented as a continuous stirred tank reactor (CSTR) with a space time of 18 s . The residence time distribution in CSTR is still very broad, which necessarily results in a broad distribution of compositions.
