In the realm of chemical synthesis, efficiency and sustainability are paramount. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to advancing these principles through the development of cutting-edge catalysts. Our hyperbranched DMAP catalysts, immobilized on nano-silica, stand out not only for their potent catalytic activity but also for their remarkable stability and recyclability, offering a significant advantage for industrial applications.

The challenge with many highly effective homogeneous catalysts, including DMAP, is their separation from reaction mixtures and their subsequent reuse. This often leads to product contamination, increased waste generation, and higher operational costs. Immobilizing DMAP onto a solid support, such as nano-silica, effectively transforms it into a heterogeneous catalyst, addressing these issues head-on. Our innovative approach involves creating a hyperbranched structure on the nano-silica using sorbitol, which enhances DMAP loading and catalytic performance.

The true testament to our catalyst's value lies in its longevity and reusability. In rigorous testing, our hyperbranched immobilized DMAP catalysts have demonstrated exceptional durability. After undergoing ten successive reaction cycles for acylation processes, the catalysts retained over 94.9% of their original catalytic activity. This remarkable stability means that the catalyst can be employed repeatedly without significant loss of performance, a critical factor for economic viability and environmental sustainability in large-scale chemical production.

This high degree of recyclability translates directly into reduced costs for manufacturers. By minimizing the need for fresh catalyst input and simplifying separation procedures, our immobilized DMAP catalysts offer a more cost-effective solution compared to traditional homogeneous DMAP. Furthermore, the reduction in catalyst waste contributes significantly to greener chemical processes, aligning with global initiatives for environmental protection and sustainable development.

The application of these stable and recyclable catalysts is broad, spanning pharmaceutical synthesis, fine chemical production, and the development of advanced materials. For instance, in the synthesis of Vitamin E succinate, the ability to reuse the catalyst efficiently streamlines the production process and lowers its environmental impact. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing catalytic solutions that not only enhance reaction efficiency but also promote sustainable manufacturing practices. Our hyperbranched immobilized DMAP catalysts represent a forward-thinking approach to catalysis, paving the way for cleaner, more economical, and highly effective chemical synthesis.
