In addition, bismuth neodecanoate can be processed through a simple separation and recycling process after the reaction, reducing waste emissions and in line with the concept of green chemistry.

Comparison with traditional catalysts

To understand the advantages of bismuth neodecanoate more comprehensively, we compare it with several common traditional catalysts, including titanate, aluminate, stannate, etc. These traditional catalysts are widely used in the fields of organic synthesis and polymerization, but they also have some limitations, such as low catalytic efficiency, poor selectivity, and great environmental impact. By comparing the performance of bismuth neodecanoate with these traditional catalysts, we can see more clearly the unique advantages of bismuth neodecanoate.

1. Catalytic efficiency

Catalytic efficiency is one of the important indicators for evaluating catalyst performance. As a highly efficient Lewis acid catalyst, bismuth neodecanoate can achieve rapid reaction rates at low doses. Studies have shown that in transesterification reaction, the catalytic efficiency of bismuth neodecanoate is several times higher than that of traditional titanate. For example, when studying the transesterification reaction catalyzed by bismuth neodecanoate, Miyatake et al. (2008) found that when using bismuth neodecanoate as a catalyst, the reaction time was shortened from the original 24 hours to 6 hours, and the product yield reached 95 %above. In contrast, when titanate is used as a catalyst, the reaction time is as long as 48 hours, and the product yield is only about 70%.
