In this work, self-condensation reaction of 2-methylfuran and its cross-condensation reactions with furfural and its hydrogenation products (2-pentanone, n-butanal, gamma-Valeractone, angelica lactone, levulinic acid, and furan) have been implemented to produce high carbon (C14-C16) transport fuel precursors. Sulfonic acid catalysts with and without alkyl chain linkers and sulfonic acid functionalized ionic liquids supported on fibrous nano-silica (KCC-1) were synthesized and investigated for these reactions. The activity and selectivity of the synthesized catalysts with respect to acidic amount, acidic strength, hydrophobicity, and surface properties were investigated. Among the synthesized catalyst, sulfonic acid-functionalized KCC-1 based catalysts showed higher conversion and selectivity due to its easy accesible acidic active site with appropriate acid strengh and hydrophobicity. The catalysts were recyclable for more than four cycles. |
