As the applicability of MOFs progresses, the demand for production of large quantities in a safe and reproducible manner is constantly growing. UiO-66 is considered to be one of the most stable MOFs and for this reason it is attractive for a wide range of applications. This work describes the upscaled continuous synthesis of UiO-66 and its derivatives by implementation of a simple milli-structured reactor. High quality material can be produced within 8 min of reaction under unprecedented reproducibility and Space time yields up to 7162 kg m⁻³ d⁻¹. The optimization of the reaction was carried out in a smaller reactor where the effects of concentration, crystallization agent (HCl) and temperature were studied and the best conditions were applied in a bigger reactor capable of delivering up to 200 g d⁻¹ in just 40 mL of reactor volume. Finally, UiO-66 derivatives were also synthesized while the reactor and process stability were tested through a number of long runs.

改进的UiO-66连续合成，可实现出色的生产率

随着MOF的适用性发展，以安全且可复制的方式进行大量生产的需求不断增长。UiO-66被认为是最稳定的MOF之一，因此，它在广泛的应用中具有吸引力。这项工作描述了通过简单的毫结构反应器的实施规模化的连续合成UiO-66及其衍生物。可以在反应8分钟内以前所未有的可重复性生产出高质量的材料，时空产率高达7162 kg m ^-3 d ^-1。反应的优化是在较小的反应器中进行的，在该反应器中研究了浓度，结晶剂（HCl）和温度的影响，并在较大的反应器中应用了最佳条件，该反应器仅需40 mL即可输送高达200 gd ^-1反应器体积。最后，还合成了UiO-66衍生物，同时通过许多长期试验对反应器和工艺稳定性进行了测试。
