The Invention
UW-Madison researchers have developed a novel esterification catalyst comprising bismuth and titanium. Conventional industrial esterification reactions leverage tin or antimony-containing catalysts. While efficient, both tin and antimony can be toxic, and alternative catalysts (e.g., titanates/zirconates (TYZORS)) are known for being unstable in water (a byproduct of esterification reactions). These bismuth and titanium catalysts address these limitations, providing an alternative for esterification reactions while avoiding toxicity and stability issues.
