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. %U https://ijcce.ac.ir/article_6687_a7e84ebe49c5618e54af1f2fe294fe00.pdf
