The military continues to be interested in the development of Insensitive Munitions (IMs) while maintaining the effectiveness of the High Explosive (HE) composition. For example, 1-methyl-3,5-dinitro-1,2,4-triazole (MDNT) bridges the technical gap between Comp-B and IMX-104 through melt casting, while maintaining the performance and effectiveness of existing products. MDNT is currently being synthesized through Batch Chemistry (BC). However, synthesis through BC has shown problems in scalability, yield, and throughput, and generates large amounts of synthetic by-products, resulting in low economic efficiency and environmental problems. Accordingly, there is an urgent need for a more economical and environmentally friendly synthesis method that can replace BC. Flow Chemistry (FC) is emerging as a new way to replace BC because of its ease of scale-up, easy yield improvement, low synthetic by-products and the ability to perform the synthesis process very safely. The FC process is also attracting attention as a new alternative for developing new synthesis methods that were not possible in BC because of their excellent heat transfer capabilities. This study introduces the synthesis of molecular explosives using FC process. The FC process enabled the MDNT synthesis to be performed in a more environmentally friendly and cost-effective manner, increasing operator safety. Through efficient mixing process to increase the yield of the product, minimizing the waste solvent and synthetic by-products generated during the reaction process, the product was purified quickly and easily in a continuous process to increase the purity, and increased the safety of the operator.
