Recently, China's organosilicon industry has made significant progress in the research and development of functional silanes. A research team has achieved key results in the synthesis of "aminoalkyl silane coupling agents," providing a new technological path for the localization and high-end development of high-performance composite materials, coatings, adhesives, and fiber treatment agents.

Aminoalkyl silane coupling agents are important functional monomers widely used in glass fiber reinforcement materials, mineral filler modification, and polymer surface treatment. Their amino groups exhibit strong reactivity with inorganic materials, while the alkyl silane ends can form stable bonds with organic resins, thus playing an irreplaceable role in the interface modification of composite materials. However, traditional synthesis routes suffer from low purity, difficulty in control, and numerous side reactions, which to some extent limit the promotion of high-end products.

In this study, the research team successfully developed a novel, mild reaction system by improving the ammonolysis and alcoholysis processes of chlorosilanes, effectively reducing by-product formation and increasing the yield of the target product by more than 10%. Researchers stated that the optimized process achieves innovations in catalytic systems, solvent selection, and temperature gradient control, enabling the high-purity synthesis of aminosilanes (such as KH-550 and KH-792) under more stable and environmentally friendly conditions.

Currently, this technology has achieved stable verification on a pilot production line, demonstrating advantages such as strong controllability, high equipment adaptability, and significantly reduced costs. Industry experts believe that this achievement will further promote the expansion of domestic aminosilane coupling agents in electronic packaging, building materials, automotive lightweighting, and high-performance composite materials.

In the future, the research team plans to continue studying green synthesis pathways for more active aminosilane structures and multifunctional silanes, providing continuous impetus for the innovative upgrading of organosilicon functional materials.
