Sažetak
Company research departments and institutes have just begun to adopt technologies of Additive Manufacturing (AM), such as 3D-printing to make prototypes and produce individual components. One of the examples how AM can be used in flow chemistry is producing special types of reactors for continuous production. In this paper, an approach for producing millireactor with prismatic static mixers through Fused Filament Fabrication (FFF) AM technology is presented. Base catalysed aldol condensation was chosen for case study because reagents are non-toxic and safe to use which is in accordance with green chemistry. Process intensification is shown in terms of retention time, τ of 5 min. In the traditional batch synthesis of dibenzalacetone it takes from 30 min to one and a half hour to produce pale yellow crystals with melting point in a range of 110 °C, corresponding to the literature data for trans, trans dibenzylideneacetone.
