Microreactors are small-scale chemical reactors designed to conduct chemical reactions in a controlled and efficient manner. They typically have a high surface area-to-volume ratio, which allows for better heat and mass transfer. This makes them ideal for applications in pharmaceuticals, materials science, and energy production, where precise control over reaction conditions is essential. These devices can operate continuously and are often made from materials like glass or silicon. Microreactors enable safer handling of hazardous materials and can reduce waste by optimizing reaction pathways. Their compact size also allows for easier integration into existing processes or systems, promoting innovation in chemical engineering.
