SBA-Pr-SO3H was proved to be an efficient heterogeneous nanoporous solid acid catalyst (pore size 6 nm), which could be easily handled and removed from the reaction mixture by simple filtration, and also recovered and reused without loss of reactivity.}, keywords = {Nanoporous solid acid catalyst,Sulfonic acid functionalized SBA-15,polyhydroquinolines,Solvent free conditions,dimedone}, url = {https://ijcce.ac.ir/article_6687.html}, eprint = {https://ijcce.ac.ir/article_6687_a7e84ebe49c5618e54af1f2fe294fe00.pdf} }
