The combination of mechanochemistry with continuous extrusion represents a promising approach.<\/strong><\/p>\n<p>The increasing problems with waste disposal in the chemical industry call for sustainable solutions. One particularly promising strategy is mechanochemistry, a process that has proven effective in a wide range of chemical applications. Mechanochemical reactions are environmentally friendly, as they often do not require solvents, achieve high yields, and enable short reaction times. Currently, mechanical energy is mostly supplied by ball milling, which is an established process but is limited to small production volumes. Scaling up to industrial levels has been a challenge so far. To overcome this bottleneck, continuous reactive extrusion is increasingly coming into focus. It offers the potential to transfer mechanochemical processes into industrial practice in an efficient, continuous, and resource-saving manner.<\/p>\n<p>Viviene Chantrain is conducting research on this topic as part of Prof. Dr. Borchardt's team at Ruhr University in Bochum: \u00abWe are convinced that mechanochemistry will make an important contribution to the further development of the chemical industry toward the sustainable use of resources and energy. However, since the production capacities of most ball mills are limited for safety reasons, the extruder offers an easily scalable and continuous method.\u00bb<\/p>\n<p>Using a Three-Tec ZE 12 extruder with an L\/D ratio of 40:1, Viviene Chantrain and her team developed the first direct mechanocatalytic reaction protocol for the Suzuki-Miyaura reaction* in an extruder. By coating the screws or cylinder of the extruder with a thin layer of palladium, they were able to carry out cross-coupling reactions continuously, without solvents and without the addition of molecular or powdered catalysts.<\/p>\n<p>The study highlights the delicate interplay of key process parameters such as temperature, mechanical energy input, residence time, rheology, and catalyst contact time. Targeted optimization of these parameters resulted in product yields of 36% % and 75% %, respectively, with longer reaction times. The extruder and the support provided by Three-Tec impressed Viviene Chantrain in her work: \u00abFor me, the Three-Tec extruder stands out in particular for its user-friendly and flexible design, as this allows us to use many different synthesis methods or run cascade reactions. When using it, you can clearly see how well thought-out the design of the extruder is, especially in the details. Three-Tec was always helpful when we had problems or questions. Even with our unusual special parts and very specific problems, we were always taken seriously and given competent and friendly advice.\u00bb<\/p>\n<p>The results of the research make a significant contribution to the further development of mechanocatalysis into a continuous, scalable process suitable for industrial use. With a view to the future, mechanochemistry is to be made more attractive for industrial production. In particular through further ball mill protocols that are adapted for the extruder based on the trends shown (e.g. amide bond formation, Buchwald-Hartwig coupling, Dakin reaction, Michael addition, Heck reaction or Friedel-Crafts reaction). At the same time, the geometric scale-up to larger extruders\/screws for the required reaction mixtures and their partly unfavorable rheology as well as the exact influences of the different kneading elements and their number should be further investigated.<\/p>\n<p><a href=\"https:\/\/www.three-tec.ch\/wp-content\/uploads\/2025\/11\/Viviene-Chantrain_SuzukiTSE.pdf\" target=\"_blank\" rel=\"noopener\">Here<\/a> You can find the complete paper \u00abContinuous Direct Mechanocatalytic Suzuki-Miyaura Coupling via Twin-Screw Extrusion.\u00bb.<\/p>\n\t\t\t\t<p>Viviene Chantrain wrote her master's thesis on \u00abMechanochemical synthesis by extrusion.\u00bb She is currently a doctoral student at Ruhr University in Bochum, where she continues to conduct research on \u00abScalability and sustainability of mechanochemical processes.\u00bb.<\/p>\n\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.three-tec.ch\/wp-content\/uploads\/2025\/11\/MC.jpg\" alt=\"MC\" itemprop=\"image\" height=\"333\" width=\"500\" srcset=\"https:\/\/www.three-tec.ch\/wp-content\/uploads\/2025\/11\/MC.jpg 500w, https:\/\/www.three-tec.ch\/wp-content\/uploads\/2025\/11\/MC-300x200.jpg 300w, https:\/\/www.three-tec.ch\/wp-content\/uploads\/2025\/11\/MC-18x12.jpg 18w\" sizes=\"(max-width: 500px) 100vw, 500px\" title=\"MC\" onerror=\"this.style.display='none'\"  \/>\n\t\t\t\t<p>* The Suzuki-Miyaura reaction is a chemical reaction that allows two organic molecules to be linked together by a C-C bond. The reaction connects a molecule containing a boron atom to another molecule containing a halogen atom such as bromine or iodine. A palladium catalyst is necessary for this coupling to proceed efficiently. It accelerates the reaction and enables the connection under mild conditions. In addition, a base is added, which is necessary for the catalysis cycle. The result is a new, often more complex molecule in which two carbon groups are directly linked to each other. The Suzuki-Miyaura reaction is one of the most important methods in modern organic chemistry due to its reliability and versatility. It is frequently used in pharmaceutical research, in the manufacture of active ingredients, and in materials science.<\/p>\n<h1>\n\t\tPrecise dosing\n\t\tin the milligram range\n\t\t\t\t<\/h1>\t\n\t<p><strong>In a recent series of tests, the feeding performance of our devices was examined for very small target quantities. The goal was batch feeding of 60 mg of powder with a permissible tolerance of \u00b13 % for a future project.<\/strong><\/p>\n<p>The aim of the tests was to achieve a batch weight of 60 mg (0.06 g) with a maximum deviation of \u00b1 1.8 mg. The aim was to test the technical feasibility and process reliability for this small quantity for a future customer project. A fine-grained semolina with a grain size of less than 300 \u00b5m, which is comparable to the customer's original product, was used for the tests.<\/p>\n<p>We used the smallest feeding device in our portfolio, a ZD 5 FB flat-tray feeding device, which continuously weighed the discharged quantity using a high-resolution load cell and adjusted the screw speed accordingly. The tests were carried out in our test laboratory under stable environmental conditions in order to minimize external influences.<\/p>\n<p>The tests were successfully completed: the feeding values achieved were within the tolerance range of \u00b11.8 mg. This confirmed that the device also works precisely and repeatably in the low milligram range. The measurement results also showed that fine adjustment of the parameters can achieve stable feeding performance across multiple batches. Fluctuations in material flow or bulk density had only a minor effect on the result.<\/p>\n\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.three-tec.ch\/wp-content\/uploads\/2025\/11\/Diagramm.jpg\" alt=\"chart\" itemprop=\"image\" height=\"505\" width=\"800\" srcset=\"https:\/\/www.three-tec.ch\/wp-content\/uploads\/2025\/11\/Diagramm.jpg 800w, https:\/\/www.three-tec.ch\/wp-content\/uploads\/2025\/11\/Diagramm-300x189.jpg 300w, https:\/\/www.three-tec.ch\/wp-content\/uploads\/2025\/11\/Diagramm-768x485.jpg 768w, https:\/\/www.three-tec.ch\/wp-content\/uploads\/2025\/11\/Diagramm-18x12.jpg 18w\" sizes=\"(max-width: 800px) 100vw, 800px\" title=\"chart\" onerror=\"this.style.display='none'\"  \/>\n\t<p><em>Measurement results of the tests (weight\/time)<\/em><\/p>\n\t<p>Three of the high-precision feeding devices will be integrated into a customer's production line in the future.

This allows the material to be fed back to the screw after an extrusion process, and the process can be repeated as often as desired. This improves the homogenization of the melt, for example in the case of components that are difficult to melt or products that are difficult to mix. Once the desired degree of processing has been achieved, the operator can flip the lever and the material is extruded through the replaceable nozzle opening. With our solution, the barrel can be operated normally with a standard nozzle. In contrast to other systems, there is therefore no impairment due to complex outlet geometries when extrusion without recirculation is to be performed. The extrudate then does not have to be diverted or passed through the switch valve, which significantly improves extrudability and cleanability. This allows for more options without the disadvantages of an extrusion process without recirculation.<\/p>\n\t\t<h3>\n\t\t\tExtruder for research and development of chemical reactions\n\t\t<\/h3>\n<figure itemscope itemtype=\"https:\/\/schema.org\/ImageObject\">\n\t\t\t\t<img decoding=\"async\" src=\"https:\/\/www.three-tec.ch\/wp-content\/uploads\/2025\/11\/P3.jpg\" alt=\"P3\" height=\"694\" width=\"800\" title=\"P3\" onerror=\"this.style.display='none'\" loading=\"lazy\" \/>\n\t<\/figure>\n\t\t\t\t<p><strong>Devices:<br \/><\/strong>ZE 12 HMI extruder on trolley for use in a vertical fume hood, split barrel can be operated with or without counter bearing, ZD 9 FB flat-tray feeding device, gravimetric, micro gear pump, heatable, thermostat for deep-freezing the barrel in the final zones<\/p>\n<p><strong>Industry\/Use:<\/strong><br \/>Research and development of chemical reactions, polymer production, melt granulation, powderization in the barrel<\/p>\n<p><strong>Special feature:<br \/><\/strong>The material is melted and then rapidly cooled again in the final barrel zones to allow it to solidify and be pulverized.
