On the basis of efficient and recyclable criteria for catalytic conversion of CO2 into cyclic carbonates, functionalized polymeric ionic liquids grafted onto the silica (PIL@SiO2) are explored by the polymeric method herein. Among all the prepared PIL@SiO2, the PIL@SiO2 loaded with a high mass fraction (50%) of PIL is the best in catalytic activity, achieving 91% PO conversion, nearly 50% saved than...
The hyper-cross-linked porous poly(2-naphthol) fabricated by the Friedel–Crafts alkylation of 2-naphthol has been functionalized with sulfonic acid to obtain a solid acid catalyst. The catalyst is applied for the protection of phenol, alcohols, thiols, amines and aldehydes with acetic anhydride at room temperature. The catalytic protection using the new solid acid is featured by achieving high yield...
