AI Technical Summary
The recovery of triflate metal salts is complex and has low yields. The existing methods have problems with the formation of by-product salts and heterometal inclusion compounds, resulting in low purity.
By reacting trifluoromethanesulfonic acid with metal alkoxides within a specific temperature range, high-purity triflate metal salts are prepared and used as esterification catalysts and transesterification catalysts for hydroxycarboxylic acid esters to achieve efficient catalysis reaction.
It simplifies the synthesis process, increases the yield, avoids the formation of by-product salts, significantly improves the purity of the product, and exhibits high activity and selectivity in esterification and transesterification reactions, reducing corrosion tendencies.
