To achieve strong chemical bonding of HPAs on silica surface, reduce HPA leaching in polar reaction media, achieve non-corrosivity and recycling facility, it is crucial to use silicas functionalized with organic bases or anion exchangers. The catalysts were evaluated in model acid (synthesis of ETBE and AcOEt) and oxidation reactions (oxidative cleavage of 2-hydroxycyclohexanone, epoxidation of cyclooctene and limonene).
