AI Technical Summary
The existing methods for producing secondary alkyl (meth)acrylates through esterification of acrylic or methacrylic acids with olefins require high temperatures, long reaction times, and result in low yields with significant by-product formation, limiting efficiency and cost-effectiveness.
The use of fluorinated sulfonic acids as catalysts in the esterification reaction of acrylic or methacrylic acids with olefins allows for lower temperature and shorter reaction times, achieving high yields and reducing by-product formation by maintaining the reaction at equilibrium with excess reactants, which can be reclaimed and recycled.
This method provides high-purity secondary alkyl (meth)acrylates with increased yields and reduced by-product formation, offering a more economical and efficient process for producing these monomers, which are crucial for pressure-sensitive adhesive applications.
